Little Green Max Pet SmartMix Portable Carpet and Upholstery Cleaner
Last verified by the Lifetime Picks Editorial Team
Why we picked it
Portable and one-hand carry - cleans stairs, upholstery, mattresses, and car interiors a full-size unit can't reach
Bissell's Little Green Max Pet is the portable extractor that handles the messes a full size carpet machine can't reach, couch cushions, mattresses, stairs, car interiors, and the pet accidents that never happen near where you'd want to drag a 40 pound upright. SmartMix Technology auto doses the cleaning formula so you stop eyeballing solution ratios, and the Self Cleaning Tough Stain Tool flushes itself after each use so the nozzle doesn't clog and seize, the failure mode that kills most portable spot cleaners. Separate clean- and dirty water tanks mirror the dual tank architecture of commercial extractors in a unit you can carry one handed. r/HomeImprovement, r/CleaningTips, and r/dogs keep the Little Green line within arm's reach for fresh accidents: spray, scrub, and extract before a stain sets. Replacement tanks, hoses, and tools are sold by Bissell, and every Pet line purchase supports the Bissell Pet Foundation's rescue work.
