The Bissell SpotBot Pet might actually be a dog or cat owner's best friend. Puppy training "accidents," spit-up hairballs, the occasional half-eaten chicken carcass: with pets in the house, cleaning challenges come with the territory.

Some of the worst mishaps happen when there's no one around, creating set-in stains that resist the most stubborn scrubbing with a sponge or rag. This pet-friendly compact deep cleaner does all its work hands free, meaning users can fold laundry, wash dishes, even walk the carcass-scatterer while the mess gets cleaned up.
