The Bissell Little Green (model 1400B) is a portable wet-vacuum-style carpet and upholstery spot cleaner that went viral on TikTok for lifting stubborn stains on rugs, couches, mattresses, and car interiors. It has a 48-ounce clean water tank, a 15-foot cord, and comes with a brush tool, a self-cleaning "HydroRinse" hose attachment, and a trial bottle of Bissell's Spot & Stain formula. Reviewers who tested it over weeks or months land in a similar place: it's genuinely effective on fresh and moderate stains, well-designed for storage, and affordable next to a rental steam cleaner — but it has real limits on hose length, noise, and how deep it can reach into old, set-in messes.
What reviewers consistently praised
CNN Underscored's Molly Flores called setup "a breeze," noting the whole assembly — including attaching the hose holster with a Phillips-head screwdriver — took about 30 seconds, and singled out the clip-based hose and cord storage as a genuinely well-thought-out design touch. She was especially impressed by the clear intake nozzle, which lets you visually confirm when the machine has stopped extracting liquid, and by the crevice tool, which let her clean the tufting and buttons on an upholstered chair that regular vacuuming had missed. On stains, she found the Little Green removed soy sauce and red wine vinegar "almost immediately," and cleared an olive oil stain after several passes without needing a separate grease-specific remover. Reader's Digest's Bryce Gruber, testing it on a high-traffic area rug, an antique kilim with a pet-urine stain, and a truck's fabric seats, called the results "everything I'd ever hoped for," saying it lifted dried-in coffee stains "almost instantly" and fully removed a pet-urine stain from her antique rug without damaging its natural dye. Family Handyman's Sheri Kaz, who used it for several months, praised its light weight, the long 15-foot cord, and its ability to suck a fresh coffee spill out of a fabric sectional in minutes.
What reviewers consistently pushed back on
The most consistent complaint across all three reviewers is the 4-foot cleaning hose. Kaz said it "could use a few more feet" to comfortably reach the back of a tall chair or deep couch, and that because it doesn't swivel at its base, she spent a lot of time repositioning the whole unit for a comfortable angle. Flores agreed, noting she had to stop and reposition the machine several times to cover her full couch, and separately flagged that the unit has no built-in holder for its attachments and that the clean/dirty water tanks are only labeled with easy-to-miss embossed lettering. Noise was Kaz's other major caveat: using a decibel-meter app, she measured the Little Green at 82.2 dB — close to a loud vacuum and well above her own vacuum's 67.8 dB reading — and cited Hearing Health Foundation guidance that sustained exposure above 70 dB can damage hearing over time. On cleaning performance, Kaz's results were mixed on old messes: five-year-old pet stains on a white shag rug were visibly freshened but not fully removed even after two treatments, and heavy-handed spraying left a faint over-spray ring on a cushion that took roughly eight hours to dry. Reader's Digest's Gruber noted the machine is built for spot-cleaning smaller areas rather than whole rooms, and that its included trial bottle of solution only lasts two to three uses before you need to buy more.
What reviewers liked
- Removes fresh food, drink, and pet stains quickly — often in one or two passes
- Clear intake nozzle shows exactly when extraction is done
- Compact, lightweight (under 10 lb), and easy to store between uses
- 15-foot cord gives plenty of reach without changing outlets
- Crevice tool works well for detailing upholstery seams and tufting
What reviewers flagged
- Short, non-swiveling 4-foot hose requires frequent repositioning
- Measured at 82.2 dB in one test — louder than a typical vacuum
- No storage holder for the included attachments
- Old, deeply set-in stains may only fade, not fully disappear
- Overspray can leave cushions damp for hours and a faint ring if overused
How it compares to alternatives
Reviewers who've used both the Little Green and larger machines consistently frame it as a spot-cleaner, not a whole-room carpet shampooer. Kaz compared it favorably to a rented full-size carpet cleaner she'd used years earlier, saying the Little Green was far less hassle to transport and set up, though she noted Bissell's own lineup includes step-up models — the Little Green HydroSteam and Little Green Pet Deluxe — that add steam cleaning or extra pet-focused tools for a higher price. Flores, who has also tested competing machines like the Dyson Submarine, noted the missing attachment storage is a problem she's seen on other brands too, not unique to Bissell. None of the three reviewers tested it head-to-head against a rental unit like a Rug Doctor, but all three agree it isn't meant to replace one for cleaning an entire carpeted room — its 48-ounce tank and compact head are built for chairs, rugs, stairs, car interiors, and mattress spots rather than wall-to-wall carpet.
Before you buy: what to check
If your main use case is fresh spills and pet accidents on furniture, rugs, or car seats, all three reviewers say the Little Green handles that well. If you're hoping to fully lift years-old, deeply set stains, temper your expectations — Kaz's shag-rug test suggests you may see fading rather than full removal. If noise is a concern in your household, know that it tested louder than a standard vacuum in Kaz's measurement. And if you're cleaning larger upholstered pieces like a full sectional, budget extra time for repositioning, since reviewers agree the hose is on the short side.
Quick answers to common questions
Does it leave furniture soaked? It can if you spray too much solution — Kaz reported an eight-hour dry time after being heavy-handed with the trigger on a foam cushion. Reviewers recommend spraying sparingly and getting close to the stain rather than misting from a distance.
Is it loud? Yes, relative to a standard vacuum — Family Handyman's decibel-meter test measured it at 82.2 dB.
Will it get out old pet stains? Results are mixed on long-set stains. Reader's Digest reported success on an old pet-urine stain on an antique rug, while Family Handyman's five-year-old shag rug stains only faded after two treatments.
Is it worth the price?
Amazon prices shift regularly, so check the live price on the button below rather than relying on a fixed number here. Reviewers broadly agree the Little Green earns its price against the alternative of renting a full-size carpet shampooer or paying for a professional cleaning, especially for spot-treating furniture, rugs, stairs, and car interiors. It's less convincing as a whole-room carpet cleaner or as a tool for erasing years-old stains — reviewers suggest tempering expectations there.
Our take, based on the roundup
The consistent thread across these reviews is that the Little Green does exactly what it's marketed for — fast, effective spot-cleaning of fresh-to-moderate stains on carpet and upholstery — while falling short as a substitute for full-room carpet cleaning or a guaranteed fix for years-old, deeply set stains. The short hose and the noise level are the two caveats that show up in every hands-on test we read.
