Spoiler Alert: The Little Green Portable Carpet Cleaner is one of our favorite household cleaning supplies. Check out our other recommended products in Household Cleaning Essentials: Our 15 Top Picks.

Quick backstory: I previously owned the Bissell SpotBot Pet and ran it into the ground. The hose ripped, and apparently, replacement hoses aren’t a thing. (?!)

I went about a year without any deep-cleaning tool, which isn’t ideal when you have a few cats and a natural tendency to spill… absolutely everything. I finally decided on another Bissell powerhouse: Little Green.

The Little Green is a portable carpet cleaner designed to lift tough, embedded stains from upholstery and carpet. But does it live up to expectations?

This is my complete Little Green Machine review. Keep reading to learn how this machine works, its key features, what I like (and don’t), and why I recommend it!

Bissell Little Green Machine Sneak Peek

The Bissell Little Green cleaning machine is a little beast. Its wide stream and powerful suction make it highly effective against various stains and spills, from pet accidents to paint. A lightweight, compact, and easy-to-set-up cleaner, the Little Green is a must-have for keeping upholstery and carpets stain-free.

A Quick Look at the Bissell Little Green Machine

The Little Green is arguably the most recognizable member of the so-called “Little Green Family.” This super portable deep cleaner features a 48-ounce water tank, a built-in carrying handle, a long power cord/plug, and three specialized tools.

Though relatively compact at <10 pounds (4.5 kg), the Little Green is a deep-cleaning giant. Its wide stream, powerful suction, and tough bristles help lift stains from fabrics, carpet, and vehicle interiors. The Little Green works best against small messes and spills.

About the Brand

Bissell is a family-owned business launched in 1876 and is the leading manufacturer of floor care products. It currently holds 20% of the total market share and secured its peak revenue—$800 million—in 2022. They also donate a portion of their sales to the Bissell Pet Foundation, which aims to help homeless pets. 

Their line-up includes vacuums, purifiers, formulas, steam cleaners, and carpet cleaners. 

The Little Green is also far from the “first” deep cleaner we’ve seen from the brand. In 1979, they launched their first and, by the late ‘80s, developed a more innovative model that didn’t require a water connection.

What’s in the Box?

I bought the standard Little Green (model 1400B), which comes with:

  • Little Green
  • Flex hose clip
  • Flex hose storage bracket
  • 3″ tough stain tool
  • HydroRinse self-cleaning Hose tool
  • Spraying crevice tool
  • 8-ounce Spot + Stain with Febreze formula
  • 1 screw

Here’s a front view of the cleaner (and everything that comes with it):

Other Versions Available

The standard Little Green carpet cleaner (the one I own) comes with an 8-ounce trial-size bottle of Spot + Stain with Febreze formula. But you can also “upgrade” your purchase to include an extra 32-ounce bottle of a different formula.

Options include:

  • 32-ounce Pet Spot + Stain Formula
  • 32-ounce Pet Pro Oxy Spot + Stain Formula
  • 32-ounce Little Green Oxy Spot + Stain Formula
  • 32-ounce Pro Oxy Spot + Stain Formula

To really level up your cleaning game, there’s also a cordless model designed for on-the-go use (i.e., in your vehicle or outdoors). It features a 25V lithium-ion battery and 165-watt motor with ~20–35 minutes of run time on a single charge, depending on the mode.

The cordless Little Green comes with the Tough Stain tool, the HydroRinse tool, and an 8-ounce bottle of Bissell Pro Oxy Spot + Stain formula. It doesn’t come with a crevice tool, though you can buy one separately.

Like the standard model, you can also “upgrade” your package with additional formula:

  • 32-ounce Little Green Oxy Spot + Stain Formula
  • 32-ounce Pet Pro Oxy Spot + Stain Formula
  • 32-ounce Pro Oxy Spot + Stain Formula

Key Features

When it comes to the Little Green, there’s a lot more than meets the eye. So, let’s take a closer look at some of its key features.

Three Included Tools + Formula

This model comes with three tools—the 3-inch Tough Stain tool, the Spraying Crevice tool, and the HydroRinse Self-Cleaning Hose tool. It also includes a small bottle of formula.

Tough Stain Tool

The Tough Stain tool is the go-to attachment when using the Little Green. It measures 3 inches (7.6 cm) wide and tall and ~4 inches (10.2 cm) from the hose connection point to the tip. Pressing the spray trigger releases a wide stream of water about the width of the tool. 

It has three rows of ½-inch (1.27 cm) long red bristles. These bristles are rough but flexible enough to agitate set-in stains without causing damage—assuming you use a gentle touch. If you use too much force when scrubbing, these bristles will bend or flatten permanently (oops).

There’s also a clear cover on the top of the tool where you can actually see what you’re sucking up. This is how you’ll gauge your progress. When the liquid comes up clear, stop spraying, and go over the area a few more times to suck up any remaining liquid. 

Warning: This can be very satisfying. 

You can clean this tool in the sink to clear some of the collected grime. However, you’ll be in a never-ending battle with the dirt and hair caught in the sides, as the clear cover isn’t removable. Short of vacuuming the area well before using the Little Green, there’s not much you can do to avoid this.

You can see the flattened bristles and the trapped debris along the sides in these images: 

tough stain tool little green

It’s also worth mentioning that this tool can feel awkward in the hand. The “natural” grip is along the base of the hose where your finger can reach the trigger. However, if you’re scrubbing with some oomph, it may feel more comfortable to grip it closer toward the bristles. 

Take some time to play around with your hand placement to find a position that works for you and doesn’t damage the bristles. 

Spraying Crevice Tool

The Spraying Crevice tool was a nice “freebie”… if you can find a way to use it (more on that in a second). It measures ~9 inches (22.9 cm) long with a ¼-inch x ¾-inch (0.6 x 1.9 cm) narrow opening and sprays a thin but powerful stream of water.

crevice tool little green

This tool is for deep-cleaning cracks, tight spaces, and edges where the Tough Stain tool can’t reach. Now, it’s a great idea in theory and works decently well along baseboards and the edges of rooms. 

But that’s about it. 

For one, there’s no scrubbing mechanism, which is half the battle when lifting stains. I can’t fault the manufacturer for that since we’re working with tight spaces that are already hard to reach with a ¼-inch (0.6 cm) wide tool. There’s only so much you can do.

The attachment is also completely black. Unlike the Tough Stain tool and its clear cover, you won’t know if you’re sucking anything up and whether you’re almost done. 

Letting water soak into fabrics and carpet can lead to mold or mildew. So don’t use this tool to aimlessly shoot water between car seats or couch cushions and expect anything other than funky smells.

I won’t knock it too much because it’s more of a bonus. But I can’t imagine this free attachment will be a major selling point. 

HydroRinse Self-Cleaning Hose Tool

The HydroRinse Self-Cleaning Hose tool is—without a doubt—the most useful tool in the entire package. It measures ~1 ½ inches (3.8 cm) in diameter and about 3 inches (7.6 cm) long. It’s mostly clear with a lime green clip for storing it on the hose when it’s not in use.

Attaching it to the hose, holding it upright, and pressing the trigger forces a flow of fresh water. The water then bounces off the clear plastic piece at the end and sends it back through the hose, clearing any debris or residue lining the inside.

hydrorinse tool little green

Bissell recommends using this attachment after each use, and I agree. In fact, I’d say it’s the most important tool because every time I’ve put the machine away without using it, I’ve had issues next time. The stream would become a pathetic dribble until I used the HydroRinse tool. 

When the water shooting into the dirt tank runs clear, you can consider the hose “clean” and store your machine. 

Note: I’m not sure whether this is just my device or the attachment in general, but mine makes a strange kazoo-like noise from time to time. 

8-Ounce Bissell Spot + Stain With Febreze Formula

Every model of the Little Green comes with a trial-size bottle of formula. You also have the choice to upgrade to include a beefier 32-ounce bottle of one of five different Bissell cleaning solutions.

The Spot + Stain formula with Febreze smells fresh and clean. Filling the clean water tank to the “Formula” line will use ~2–2.5 ounces of formula, so the trial-size bottle should last 3–4 full tanks.

If you’re looking to deep-clean everything on day one, I recommend buying one of the upgraded versions with an extra 32-ouncer included. A 32-ounce bottle—based on my math—should give you ~12–16 tanks’ worth.

Always test the solution on a small, inconspicuous area of your carpet or upholstery to check for colorfastness. For upholstery, check the manufacturer’s care instructions; make sure it has the code W or WS.

They have portable and upright carpet cleaners and specific solutions for each. Make sure you’re buying the one designed for portable cleaners. The bottle should read, “Formula made for PORTABLE carpet cleaners.”

I honestly don’t know what the difference is between the two. But because using the wrong solution may void your warranty, I recommend sticking with the portable.

Two Large Tanks

If you’re facing the Little Green’s power button and logo, the water tank will be on your left, and the dirt tank will be on your right.

Clean Water Tank

Bissell says that this tank can hold 48 ounces of water/formula. My tests show it’s closer to ~45 ounces, but that’s likely because you have to flip the tank over when filling it, making it hard to know whether it’s “level.”

Before using the LGM, you’ll fill this tank with hot water and formula. The tank is simple to remove from the device with a slight upward tug. One thing to note is that the tank will almost always drip water when you install and remove it; I’ve yet to find a way to prevent that.

It has a twist cap to remove and a nozzle with an attached straw that you’ll pull out to fill the tank. 

The tank has two lines on the inner flat side—one for formula (toward the rounded edge) and another for water (closer to the cap). These lines and the wording are really hard to see unless you’re in bright lighting and know where to look. You can mark them out more clearly with a black marker to get around this.

Do not fill the tank beyond the formula or water lines. I imagine there’s a good reason they want you to leave some room for air.

Dirty Water Tank

The dirty water tank is where the Little Green collects dirty water. Out of curiosity, I filled this tank with plain water to see its capacity at the “Full” line. It holds ~40 ounces, though the exact amount will vary depending on what you suck up.

This tank is even easier to install and remove than the water tank. To remove it, flip the plastic latch at the top and lift the tank (there should be no resistance). You can then dump the tank into the sink, clean it with warm water, and reattach it.

Unlike the water tank, a clear white line and text indicate when the tank is “Full.” It’s also extremely satisfying to see how much water you suction up, and it’s easy to dump the tank.

However, this tank does tend to accumulate residue—especially on the white portion in the middle. This part doesn’t appear to be replaceable. So, beyond filling the tank with hot water to loosen this residue and gentle swirls to agitate them, this build-up is unavoidable

You can see this build-up in the image below:

little green dirt tank residue

This tank will begin to smell the longer you let the dirty water sit. Always dump the tank after each session or whenever you reach the Full line (whichever comes first).

This water may also contain clumps of hair or thick particles that can clog a drain, so be careful about which drain you pour it down! You can limit this build-up by vacuuming the area with a dry vac first.

Physical Construction

Let’s look deeper into the Little Green Machine’s physical build.

Size + Weight

The Little Green is rather compact and low-profile at ~19 inches (48.3 cm) long, 14 inches (10.2 cm) tall, and ~10 inches (25.4 cm) wide with the hose wrapped around it. You can easily store it in a small storage closet or cabinet. 

It features a thick, wide-grip handle that fits nicely in the hand and is easy to carry. At just 9.65 pounds (4.4 kg), the LGM is also relatively lightweight as far as portable carpet cleaners go. 

For comparison, here’s how it stacks up to the competitors:

  • Shark PX201 StainStriker: 8.5 pounds (3.9 kg)
  • Shark PX202BRN StainStriker: 8.51 pounds (3.9 kg)
  • Kenmore KW2001: 10.23 pounds (4.6 kg)
  • Dirt Devil Portable Spot Cleaner: 11.03 pounds (5 kg)
  • Hoover ONEPWR CleanSlate: 13.32 pounds (6 kg)

I weighed mine with both tanks attached (empty), the cord wrapped up, and the Tough Stain tool attached and found it weighed exactly 10 pounds (4.5 kg). I also filled the water and dirt tanks to maximum capacity to see how much it weighs when full… 15 pounds (6.8 kg).

The Hose, Attachments, + Cord

With a 4-foot (1.2 m) long hose and a 15-foot (4.6 m) electrical cord, the Little Green provides plenty of reach. The cord features a quick-release latch for immediate access and is easy to wrap up before storage.

The hose is green (to match the rest of the machine), ribbed, and rather flexible. It rotates at the base of the attachment for more flexible cleaning and limited hose bending. This is one of my favorite features after retiring my SpotBot due to a ripped hose. 

Though long for a cleaner, the 4-foot (1.2 m) hose may not be long enough for reaching higher furniture—like the tops of couches—without bending the hose. 


This little machine and its formula are generally safe for most upholstery and carpets. It’s compatible with stairs, vehicle interiors, carpets, area rugs, fabric, upholstery, soft surfaces, and mats. However, its tough bristles and solution may damage more delicate fabrics—especially those that shouldn’t get wet. 

For more stubborn stains, you can maximize your cleaning power with pre-treatment. All you have to do is spray the solution onto the stain and let it sit for 3–5 minutes. Then, scrub and suction as usual. 

(Limited) One Year Warranty

Like many products, the Little Green has a limited one-year warranty that you can view here. It states that the manufacturer may send you a new, refurbished, or used replacement machine (or parts) if any parts malfunction or are defective.

But—and this is very important—the warranty also requires you to use the device exactly as described in the user manual. If you “neglect” the machine, get an unauthorized repair, or use it in any other way (such as using a different cleaner), you void the warranty.

The one-year warranty is great to have in your back pocket if the worst happens. However, it also prevents you from “customizing” your cleaning experience—such as using different cleaners in the tank.

How To Use the Little Green Machine

The initial set-up will take ~5 minutes and requires a Phillips head screwdriver. Let’s quickly review how to install the hose clip and bracket, fill and dump the tanks, and use the included tools.

Assembling the Hose Clip + Bracket

how to install the fhe flex hose bracket on the little green

Before you do anything else, you’ll want to set up the hose clip and bracket. These plastic pieces let you secure the hose when not in use and preserve storage space.

Here’s how to assemble it:

  1. The smaller plastic piece is the flex hose clip. It’ll sit at the bottom of the front of your device and give the hose a clear path to warp around the LGM.
  2. Slide the hose clip into position until it snaps into place.
  3. The larger plastic piece is your flex hose storage bracket. This will go on the back of the machine to the left of the cord storage. 
  4. Line up the screw holes and secure the screw in place with a Phillips head screwdriver.
  5. Wrap the hose around the machine so it travels 1) through the hose clip and 2) up and into the bracket. 
  6. Turn the bracket latch to your right to lock the hose into place. 

Filling the Water Tank

how to fill tank in little green

Next, fill the tank with water and a Bissell cleaning solution. You can technically use a homemade mix or another brand’s products, but I’d advise against that for two reasons.

For one, using anything other than a recommended Bissell solution will void your machine’s warranty. Second, other products may clog up internal parts or impact their performance.

Here’s how to fill the tank:

  1. Gently remove the tank by lifting it. The tank has a nozzle at the bottom that clicks into place. If you’re looking at the machine’s logo and power button, it’ll be the one on your left.
  2. Unscrew the nozzle cap.
  3. Fill the tank to the “Formula” line with cleaning solution. This line is on the flat side of the tank opposite the nozzle. 
  4. Fill the tank to the tank’s “Water” line with hot water—but not so hot that it’s boiling. Hot water (~140 °F) typically dissolves dirt and grime more effectively.
  5. Put the cap back on and give the tank a little shake.
  6. Replace the tank. Make sure it slides securely into place.

Using the Tough Stain Tool

how to use little green tough stain tool

The 3” Tough Stain tool works best against stubborn stains. Pressing the trigger on the hose handle releases a wide spray.

This tool also has three rows of tough bristles for scrubbing and a clear cover so that you can see what you’re sucking up. It works on upholstery, stairs, rugs, carpets, and fabrics.

Here’s how to use it:

  1. Attach the Tough Stain tool to the end of those hose so that the two protrusions (the spray line) line up and connect. It should click into place.
  2. Hold the tool close to the stain—about an inch (2.5 cm) above it.
  3. Press the trigger to spray the stain.
  4. Release the trigger and scrub the area with the bristles. Gently work it into the fabric with back-and-forth motions.
  5. Using downward pressure on the stain, slowly pull the tool toward you.
  6. Continue step #5 until no more dirt comes up.

Using the Spraying Crevice Tool

how to use little green crevice tool

The Spraying Crevice tool is your standard vacuum crevice tool cranked up a notch. Pressing the hose trigger releases a narrow and powerful stream of water.

This tool is designed for narrow or tight spaces where the Tough Stain tool doesn’t reach. You can use it along edges, between cushions, in the crevices of furniture, or along baseboards. 

Here’s how to use it:

  1. Attach the Crevice tool to the end of the hose. Line up the two protrusions (the spray line) and click it into place.
  2. Position the tool about an inch (2.5 cm) above the area you want to clean.
  3. Press the trigger to saturate the area.
  4. Release the trigger and pass the tool over the area to suck up the water.
  5. Continue step #4 until no more dirt comes up.

Emptying the Dirt Tank

how to empty the dirt tank on little green machine

The dirt tank is one of the most satisfying parts of the LGM. Emptying it is necessary to maintain suction, avoid overflowing, and prevent the build-up of odors, bacteria, and residue.

Empty this tank once it reaches the “Full” line or after each session—whichever comes first. The longer you let it fester, the more likely it’ll begin to smell and coat the inside of the tank with a gross residue.

Here’s how to dump this tank:

  1. Turn off the device and unplug it from the wall. 
  2. Lift the latch on top of the dirt tank and pull it from the unit. It should slide out rather easily. If you’re looking at the machine’s logo and power button, it’ll be the tank on your right.
  3. Bring the tank to a sink. Do not pour it outside, as the cleaning solution can harm gardens and plants. 
  4. Empty the tank’s contents into the sink.
  5. Clean the inside of the tank with warm water. Give the tank a little swirl when there’s water in it to remove loose debris along the inside. (Do not shake it!)
  6. Let the tank air dry completely before reassembling.
  7. Reattach the tank to the machine and flip the latch back down.

Using the HydroRinse Self-Cleaning Hose Tool

how to use little green hydrorinse hose cleaning tool

The HydroRinse Self-Cleaning Hose tool (say that three times fast) is a nifty tool designed to flush the dirt and debris from the hose’s interior. Using it after each use will help prevent the build-up of odors, mold, and residue in the flex hose.

Here’s how to use this tool:

  1. Attach the HydroRinse tool to the end of the hose. It should slide cleanly into place.
  2. Hold the hose (with the tool attached) in an upright position.
  3. Turn the machine on.
  4. Hold the trigger for ~30 seconds to clean the gunk from the hose. 
  5. You’ll see the dirty water from the hose shoot into the tank—stop when it runs clear.

Does It Actually Work? [The Test Results]

TL;DR: Yes.

In the three months I’ve owned this machine (at the time of writing), I’ve used it to:

  • Remove the lingering smell of cat urine from sofa cushions.
  • Lift a massive black acrylic paint stain from the carpet (don’t ask how this happened; everything that could’ve gone wrong in that moment did).
  • Clean and refresh vehicle floor mats.
  • Remove years-old carpet stains that I figured were permanent.

But the best way to prove it works—and show where it falls short—is to actually test it. So, here are a few specific examples of how and when I’ve used it, including before-and-after photos:

Before + After: Vehicle Floor Mats

Dark car mats are especially tricky because while many stains don’t show, they can still hold onto plenty of dirt. I last cleaned these babies about three or so months ago.

Before whipping out the LGM, I vacuumed each mat using my upright vacuum’s TurboBrush tool. This will limit the loose hairs and dirt particles and leave just the embedded stuff behind. I sprayed all four mats with the cleaning solution, scrubbed ’em with the Tough Stain tool, and then sucked up the gunk.

Now, for the big reveal… this is what the dirt tank looked like after I finished cleaning in about 15 minutes:

little green machine vs car mats

Before + After: Red Gatorade

And just for sh*ts and giggles, I bought a white microfiber bathroom mat set to put the Little Green to the test. I purposely spilled red Gatorade onto one mat to see how well this machine could remove the stain.

(This was, in fact, my weekend highlight.)

I decided to start with a pre-treat because it was a red stain on a pure white rug. After letting it sit for ~5 minutes, I re-applied, scrubbed, and suctioned the solution. It took a pre-treat and two rounds of regular suctioning, but I did it in about 20 minutes.

Here’s the impressive before and after shots:

little green machine vs red gatorade

Keep in mind that your experiences with the Little Green may vary based on the fabric or carpet, stain source, and cleaning solution. Some stains may require pre-treatment or several rounds with the LGM to make them less noticeable or disappear entirely.

The Good: 7 Pros

Here are seven reasons I LOVE the Little Green:

1. Actually Removes Tough Stains

Yes, the Little Green does remove tough, set-in stains, including pet messes, red wine, dirt, and colas. More stubborn spills may require a few treatments or pre-treatment, but I’ve yet to encounter a stain it couldn’t at least make less visible. Watching the stain be “lifted” through the clear panel on the Tough Stain tool is also ridiculously satisfying. 

2. Positive Brand Reputation

With 100+ years in business, Bissell has a stellar reputation in the home vacuum community. I’ve owned several of their floor products and loved each. I’ve had the CleanView Rewind Pet and TurboClean Powerbrush Pet for years now without issue. The SpotBot was another story… but that one probably comes down to user error (whoopsie).

3. Relatively Affordable

I purchased the Little Green while it was on sale. But its everyday list price is about middle-of-the-road compared to similar models from other brands. The only downside is that you’ll need to buy formula refills when you run out. This can quickly add up if you have a busy household with pets, kids, or full-grown adults who can’t keep a drink in a cup.

4. A Customizable Cleaning Experience

This machine is ready to use from day one with its crevice and stain tools. You can also customize your cleaning experience with accessories. Bissell sells a crevice tool with a brush (which makes sense), a powered TurboBrush, and larger versions of the Tough Stain tool (among others). Make sure that any replacements you buy are legitimate Bissell products sold by Bissell.

5. User-Friendly Design

The LGM is portable and convenient, with 19 feet (5.8 m) of reach and weighing <10 pounds (4.5 kg). It can easily fit on a step (for stair cleanings), tackle small and large messes, and make your cleaning experience more flexible. The cord is also easy to wind up and release, while the water tanks are easy to install and remove—albeit with some leakage.

6. Replacement Parts Available

On top of selling crevice, Tough Stain, and HydroRinse attachments, Bissell also sells the following replacement parts:

  • Cap and insert assembly
  • Collection tank duckbill gasket
  • Collection tank
  • Cord wrap assembly
  • Flex hose storage bracket
  • Flex hose clip
  • Quick-release cord wrap

You might be able to find additional parts—like the hose—from third-party manufacturers. However, doing so may void the warranty, and it’s unclear how well these parts will work compared to the original. 

7. Fewer Odors

To those wondering, the Little Green does—in fact—eliminate set-in odors by removing the odor from its source. I’ve used it to remove the smell of embedded cat urine on various pieces of furniture. Just keep in mind that the odors you suck up will wind up in the collection tank, so be sure to empty it regularly.

The Bad: 4 Cons

Though I absolutely swear by this tool, I’ll be completely honest: it’s not perfect. Here are the four biggest downsides I’ve noticed:

1. Not Suitable for All Surfaces

Though you can use the Little Green and its formulas on most upholstery and carpet, it’s unsuitable on some surfaces. Always test for colorfastness before using it, and only use it on upholstery labeled with the code W or WS to avoid water damage. Unfortunately, this machine is also far from replacing a regular dry vacuum. Those without kids, pets, or a tendency to be messy may find it sits in the closet and collects dust most of the year.

2. Some Leakage

This is a complaint I’ve seen a lot from users online, and it’s also one I’ve experienced. Every time you remove or add the tank or an attachment, a few drops of water will leak. I have yet to find a way to avoid this, but at least it’s clean water and not dirty. As my SpotBot was on its last leg, it would suck up liquid, but after turning the machine off, the dirty water sucked up would pour right back out of the hose. The LGM is nowhere close to that severe.

3. Difficulty Cleaning Attachments + Dirt Tank

You can rinse the Tough Stain tool and dirt collection tank with water to keep them relatively clean. However, after a few uses, you’ll notice stuck-on residue that’s impossible to remove. The biggest problem areas are the sides of the Tough Stain tool (between the plastic and green part) and the large white piece in the middle of the dirt tank. This residue probably won’t impact the device’s performance, but cleaning tools should be clean… right?

4. Suction Power May Not Be Enough

While the Little Green is certainly a beast when it comes to small spills and fresh messes, it does have its limitations. Its suction power is nowhere near a traditional car detailer machine (if that’s what you plan to use it on). Deep-cleaning with this machine will also be tedious on large areas since you have to clean by hand in 3-inch (7.6 cm) chunks. Some stains are nearly impossible to remove. So don’t expect any miracles whether you’re using the Little Green or something more powerful!

The Final Verdict: Is the Little Green Worth It?

Bissell’s Little Green is a reliable carpet and upholstery cleaner and a worthwhile investment.

It’s especially useful for those with pets, kids, or adults who can’t seem to have an open cup of liquid without knocking it over and spilling it everywhere (self-own). The three tools and trial-sized formula also give you deep-cleaning power from day one. It’s portable, convenient, affordable, and extremely effective for various cleaning tasks.

But just know that there will be some leakage, it’s not the end-all-be-all if you have a particularly dirty home, and some parts will stay dirty. All in all, I highly recommend the Bissell Little Green Machine if you’re looking for a portable carpet cleaner with some oomph.

Frequently Asked Questions (FAQs)

If you’re still undecided on buying the Little Green Portable Carpet Cleaner, these FAQs may help you decide:

What Can I Put In My Bissell Little Green Machine?

You can put hot (not boiling) water and a portable Bissell cleaning solution in your Little Green Machine. Unfortunately, while DIY solutions like vinegar, dish soap, and laundry detergent may remove stains from carpets and upholstery, using them will void your warranty and could damage the machine.

Can Bissell Little Green Be Used as a Vacuum?

You cannot use the Bissell Little Green as a regular vacuum. Though it will pick up specks of dirt and loose hairs when used as a wet vac, it’s not designed to suck up completely dry debris. Its 3-inch-wide (7.6 cm) Tough Stain tool would also make regular vacuuming quite tedious.

How Long Does It Take To Dry After Little Green Machine?

It takes several hours (2-4) for carpet and upholstery to dry after using the Little Green Portable Machine. The timing depends on the humidity, how well the machine sucked up the water, and how deeply the water and cleaning solution penetrated. After, you can speed up the drying by blotting the area with a dry cloth.

Can You Use Just Water in a Bissell Little Green?

You can use just water in a Little Geen, especially if you’re “rinsing” an area. However, adding a compatible Bissell cleaning solution to the tank will maximize your cleaning power and help to loosen stains, remove set-in odors, and leave behind a fresh and clean scent.

Why Does Your Little Green Smell So Bad?

A Little Green will smell bad if you don’t empty the dirt tank or use the HydroRinse tool after each use. The longer the messes, spills, and dirt sit in the tank or hose, the more this odor will intensify. To remove it, rinse the tank with lukewarm water and use the HydroRinse tool until the water is clean.
