You’ve probably seen the viral videos. Someone spills a glass of red wine or a puppy has an "accident" on a white rug, and suddenly this little green machine appears to suck the mess into oblivion. It’s satisfying. It’s basically magic. But for a long time, the biggest headache was the cord. You’d be halfway through cleaning the stairs and—yank—the plug pops out of the wall.
Enter the Bissell Little Green Mini Cordless.
It is exactly what it sounds like: a shrunken-down, battery-powered version of the internet's favorite carpet cleaner. It’s small. Really small. Weighing in at just about 7 pounds, it’s roughly 45% lighter than the original Little Green. If you’re used to lugging around a full-sized upright carpet cleaner, using this feels like switching from a heavy suitcase to a backpack.
But does "mini" mean it actually works? Or are you just paying for the convenience of not having a tail? Honestly, it depends on what you're trying to clean. If you want to detail your entire SUV, you might run into some walls. If you just need to zap a coffee spill before it sets, this thing is a beast.

What the Bissell Little Green Mini Cordless actually does
Bissell didn't just cut the cord and call it a day. They re-engineered the whole footprint. The Bissell Little Green Mini Cordless uses a 25V lithium-ion battery and a 165W motor. That’s a lot of tech packed into a tiny chassis.
The machine operates in two distinct modes. You’ve got "Eco" and "Turbo."
Eco mode is for the light stuff—think dust, fresh water spills, or just a quick refresh of a chair cushion. It’s quieter and gives you about 35 minutes of runtime. Turbo mode is where the real work happens. It ramps up the suction to pull deep-set dirt and liquids out of carpet fibers. The catch? You only get about 20 minutes in Turbo.
- Weight: 7 lbs (empty)
- Clean Tank: 16 oz
- Dirty Tank: 13.5 oz
- Hose Length: 4 feet
- Charge Time: Roughly 4 hours
One weirdly smart feature is the BatteryBoost+ technology. It’s a bit sophisticated for a spot cleaner. Essentially, the machine knows when you’re actually pressing the tool against a surface. It ramps the suction up when it detects resistance and throttles it down when you lift the tool away. It’s a clever way to squeeze every second out of that battery.
The Car Detailing Dilemma
People love these for cars. It makes sense. No one wants to run a 50-foot extension cord across their driveway.
Because the Bissell Little Green Mini Cordless is so light, you can literally set it on the passenger seat while you scrub the driver's side floor mats. It’s incredibly portable. However, the tank size is the bottleneck. A 16-ounce clean water tank is tiny. To put that in perspective, a standard Starbucks Grande coffee is 16 ounces.
If you are cleaning a muddy floor mat, you will be refilling that tank. Multiple times. For some people, that's a dealbreaker. For others, the trade-off for not having a cord is worth the extra trips to the sink.
Is the Mini better than the standard Cordless?
This is where it gets confusing. Bissell has a "Little Green Cordless" and a "Bissell Little Green Mini Cordless."
The standard (non-mini) cordless model is beefier. It weighs about 9 pounds and has much larger tanks—around 33 ounces. It’s built for bigger jobs, like cleaning an entire sofa or a whole set of stairs in one go.
The Mini is for the "oops" moments. It’s designed to live under your kitchen sink or in a small apartment closet. It’s the tool you grab when the cat throws up at 2 AM. You don't want a heavy machine then. You want something you can grab with one hand, spray, scrub, and be back in bed in five minutes.
Maintenance and the "Yuck" Factor
One of the biggest complaints about the original Little Green was that the hose would get gross. Hair and dirty water would get trapped inside, and it would start to smell like a wet dog.
Bissell finally listened. The Bissell Little Green Mini Cordless comes with the HydroRinse self-cleaning tool. You attach it to the end of the hose, turn the machine on, and it flushes clean water through the entire hose into the dirty tank. It takes 30 seconds and actually works.
The dirty tank also comes apart. You can take the lid off and actually scrub the inside with a brush. If you’ve ever owned a carpet cleaner where you couldn't reach the gunk at the bottom of the tank, you know how big of a deal this is.
The Reality Check: suction vs. elbow grease
Let’s be real for a second. This is a 7-pound battery-operated device. It is not a professional-grade steam cleaner.
If you have a three-year-old juice stain that has bonded with your carpet fibers, the Bissell Little Green Mini Cordless isn't going to just "suck it up" effortlessly. You have to do the work. The machine sprays the solution and provides the suction, but the cleaning happens in the "scrub" phase.
You use the 4-inch Tough Stain Tool to work the OXY formula into the carpet. You scrub. Then you use the suction to pull the liquid out. A common mistake people make is not pressing down hard enough. To get the best results with a cordless unit, you really have to put some weight behind it to ensure the nozzle is making a tight seal with the fabric.
What about the battery life?
Twenty minutes of Turbo runtime sounds short. In practice, it’s usually enough for three or four "medium" messes.
Think about it: how long does it actually take to clean a 4-inch spot? Maybe two minutes? If you’re using it for its intended purpose—spot cleaning—the battery is rarely an issue. But if you’re trying to deep clean a whole area rug, you’re going to be disappointed when it dies halfway through.
Buying Guide: Who is this for?
The Bissell Little Green Mini Cordless usually retails around $130 to $160 depending on the sales. It's a bit of an investment for such a small tool.
Buy it if:
- You live in an apartment with limited storage.
- You have a pet that makes frequent, small messes.
- You are obsessed with keeping your car seats pristine.
- You hate dealing with tangled power cords.
Skip it if:
- You have a large house with wall-to-wall white carpeting.
- You plan on cleaning large pieces of furniture regularly.
- You don't mind cords and want the absolute maximum suction power possible (the corded "Mini" version is actually a bit stronger).
Ultimately, this machine is about removing friction. The easier it is to grab the cleaner, the more likely you are to actually clean the stain before it ruins your rug.
Moving forward with your Little Green Mini
If you just picked one of these up or are about to, remember to always use the right formula. The OXY-based solutions from Bissell are specifically designed not to foam up too much; using regular laundry detergent or dish soap can create a "suds-pocalypse" that can actually damage the motor.
After every use, make sure you run that HydroRinse tool. It prevents the hose from smelling and keeps the suction at 100%. Empty the dirty tank immediately—don't let it sit overnight, or you'll be greeted with a very unpleasant smell the next morning.
Keep the charger in a spot where you'll actually use it. Since it takes 4 hours to get a full charge, you don't want to be caught with a dead battery when the next spill happens. Plug it back in as soon as you're done cleaning the tanks, and it'll be ready for the next "oops" moment.

Actionable Next Steps:
- Check your carpet type: Ensure the surface you're cleaning is compatible with wet extraction (most synthetic carpets and upholstery are fine; avoid silk or non-colorfast fabrics).
- Pre-treat tough stains: For older messes, spray the area with the Bissell formula and let it sit for 5 minutes before you even turn the machine on.
- Perform a "Dry Stroke": After you've sucked up the soapy water, do 3 or 4 slow passes with the suction only (no spray) to get the carpet as dry as possible. This prevents mold and stops dirt from sticking to the damp fibers.
