5 Stars for Suction, but the "Drill Brush Hack" makes it 10 Stars
Color: Tea Green, Style: Little Green Mini
I bought the Bissell Little Green Mini to handle the inevitable "kid and pet" messes that don't justify dragging out a full-sized upright. It’s impressively lightweight, about 45% lighter than the original and, in my opinion, seemingly more durable. The 4-foot flexible hose makes it perfect for stairs and car interiors.
The Secret Sauce: The Drill Brush Pairing
While the included 4" Tough Stain Tool is great for light scrubbing, the real game-changer is pairing this machine with a soft-bristle drill brush.
My Process: I spray the stain using the Little Green’s trigger, let it sit for 30 seconds, then use the drill brush on a low setting to agitate the fibers.
The Result: This combo lifts deeply embedded dirt and old pet stains that manual scrubbing just can't touch. Once agitated, I use the Little Green’s powerful suction to pull everything out. The water in the dirty tank is always satisfyingly (and gross) dark.
Key Performance Notes
Suction Power: Don't let the "Mini" tag fool you; the suction is strong enough to leave upholstery nearly dry to the touch.
Spray Effectiveness: The built-in spray trigger is precise. It delivers a wide, even mist rather than a messy stream, which is crucial for saturating a stain without soaking the underlying foam padding.
Self-Cleaning Feature: The HydroRinse tool is a lifesaver. It flushes the hose after use, preventing that "old damp carpet" smell from developing inside the machine.
Portability: It’s small enough to store in a standard bathroom cabinet, making it much more accessible for "emergency" spills.
Pros & Cons
Pros:
Extreme Portability: Easy to carry around the house or out to the driveway.
Long Reach: The 12-foot power cord gives you plenty of room to move.
Formula Efficiency: A little bit of the Oxy Spot & Stain formula goes a long way.
Cons:
Small Tanks: Because it’s a "Mini," you will be emptying the dirty tank frequently if you’re doing a whole couch.
Loud: Like most portable extractors, it has a high-pitched motor whine.

Works as expected but won’t replace professional carpet cleaning
Color: Tea Green, Style: Little Green Mini
I’d say this little green machine was worth the money. I’ve had it for a few months, and these are my pros and cons:
Pros:
-good size, easily stored in my closet
-cord length is long enough for my needs
-gets new stains out if I act quickly after spilling
-comes with carpet cleaner (unlike if I were to rent a carpet cleaner from my hardware store)
-great for spot cleaning
Cons:
-I can only spray the cleaning solution if the vacuum feature is turned on. I would like to spray and then wait a while, then turn on the vacuum feature. I could be doing this wrong, but I haven’t figured out a way to change this feature.
-the suction isn’t as strong as I’d like. I recently got my carpets professionally cleaned, and I understood why that service is still necessary even if I’m spot-cleaning with my little green guy often.

Great for Small Messes, but Not a Full Carpet Cleaner Replacement
Color: Tea Green, Style: Little Green Mini
I’ve been using this for spot cleaning, and overall it’s one of those tools that’s really handy to have around.
The biggest strength is how well it handles small messes. It sprays, scrubs, and sucks up stains pretty effectively—especially on things like car seats, couches, or small carpet spots. The suction is surprisingly strong for such a small unit, which is why these are so popular for quick cleanups and pet messes. ()
It’s also compact and easy to carry, so you’re not dragging out a full carpet cleaner every time something spills. That’s honestly where it shines the most.
On the downside, it’s not perfect. The tank is pretty small, so you’ll be refilling and emptying it if you’re doing anything more than a few spots. () The hose and cord length are decent but can feel a little limiting depending on where you’re cleaning.
Another thing is that while it cleans well, it can leave things a bit damp afterward, so drying time is something to keep in mind. And like most machines in this category, it can get a little loud.
Overall, it’s a really solid little machine for what it’s meant to do—quick, targeted cleaning. Just don’t expect it to replace a full-size carpet cleaner for deep cleaning large areas.

Super efficient
Color: Tea Green, Style: Little Green Mini
Easy to use. Light weight. Great on upholstery and carpet spots. Tank is not large enough to do area rugs or carpet, but great for smaller cleanups.

Best machine I have found thus far
Color: Tea Green, Style: Little Green Mini
Have always had pets, cats and dogs. Tried many different cleaning machines. This one is by far the best. Compact, easy to clean, and thoughtfully designed. For example, the waste reservoir is easy to flush out, eliminating bad smells. The hose is easy to rinse out using gravity or by turning on the suction briefly. And the hand held part has a removable guard that allows easy cleaning. Also, the power cord is a good balance between too much and too little length. Whoever designed this obviously gave it some thought when it comes to maintenance and avoiding tricky cleaning. This machine never stinks if cleaned after each use. One last thing, the soap and water tank is large enough to get lots of jobs done, especially if you have a sneaky chihuahua who urinates as he pleases.
