The Bissell Revolution HydroSteam 4120 performs well in stain cleaning tests, particularly with syrup stains, thanks to its steam functionality. However, it leaves carpets wetter than competitors and requires frequent tank refills and emptying. Tom's Hardware called it a 'well above average performer' in stain tests, but noted it's expensive and has below-average suction. It's best suited for users seeking steam cleaning benefits, though those wanting drier results should consider alternatives.
