The $124 spot cleaner pet owners swear by (and 4 more for tougher messes)

The Little Green has been around for years, and that track record is the main reason it tops our list. Owners consistently report that it lifts fresh pet accidents, coffee and food stains from carpet, couches and car seats with a few slow passes. It has separate clean and dirty water tanks, a flexible hose and a stain tool, and it is light enough to carry up stairs with one hand. The trade-off is size. The tanks are small, so a large area means several trips to the sink, and it is a corded machine. For everyday spot cleaning, few machines offer more for the money. Read our full review

If the Little Green feels too small for your household, the SpotClean Pet Pro is the step up most reviewers point to. It carries noticeably larger tanks, so you can work on a whole stair runner or a big area rug without constant refills. Owners describe the suction as strong, and the larger brush tools scrub set-in stains more aggressively. It is heavier and bulkier, which matters if you store it in a small closet or carry it between floors. For homes with more than one pet, or anyone who also cleans car interiors and upholstery regularly, the extra capacity is worth the higher price.

The CleanSlate Plus is the most common rival to the Little Green, and it holds up well on paper. It is similarly compact, uses separate tanks and includes a hose with a scrubbing tool. The feature owners mention most is the hose-rinse function, which flushes clean water through the hose after you finish so leftover pet mess does not sit inside it. Reviews suggest suction is comparable to the Bissell for small jobs. Some owners find the tank latches a little fiddly. Pick it if you prefer Hoover, find it on sale, or want the easier hose cleanup.

Speed matters with pet stains, and the Pet Stain Eraser PowerBrush is built for grabbing fast. It is a cordless handheld with a motorized brush, so you spray, scrub and suction in one motion without plugging anything in. Owners like it for fresh accidents, stairs and cars. The compromise is capacity and runtime. The tanks are small and the battery is meant for quick jobs, so it is a poor fit for an entire rug. Think of it as the cleaner that lives in the hall closet for emergencies, paired with a corded model or a rental for deep cleaning.

Rug Doctor is best known for the big machines you rent at the grocery store, and its portable cleaner borrows some of that heavy-duty focus. Owners describe it as solidly built with strong suction, and it is a good match for older stains and odors that lighter machines struggle with. It is larger and louder than the compact Bissell and Hoover models, and the price sits a little higher. If you have tried a small spot cleaner and been underwhelmed, or you clean a lot of carpet in high-traffic areas, this is the one to consider.
