Bissell's Revolution HydroSteam adds a steam pretreat stage to a conventional upright carpet cleaner, and that is what it is for: sticky, set-in stains that soap and hot water alone leave behind. Vacuum Wars scored its stain removal 89.2 against a field average of 83.5. The trade is extraction - carpets come up wetter than average, the tanks need refilling often, and coverage is only about 105 square feet per clean tank. Buy it for stain removal, not for fast whole-house cleaning.
Full review
Steam as a pretreat, not as the whole clean
The HydroSteam's distinguishing feature is a steam pretreat mode that runs ahead of the wash. Family Handyman's Allison Robicelli described it as working like a flamethrower against stubborn stains, breaking down set-in messes in fewer passes than a soap-and-water machine manages. Vacuum Wars' stain testing bears that out with a score of 89.2 against a category average of 83.5. Sticky substances are where the advantage is clearest; ordinary ground-in soil does not need the steam and does not benefit much from it.
Weak extraction leaves the carpet wet
The counterweight to the steam is suction. The HydroSteam pulls less water back out than most uprights, so carpets stay damp noticeably longer after a pass, and the quick-dry mode narrows that gap without closing it. Because the machine also uses a lot of water per pass, Vacuum Wars measured coverage at about 105 square feet per clean tank against roughly 137 for the field - which means more interruptions to refill the clean tank and empty the dirty one on any job bigger than a single room.
Twenty-two pounds and a screwdriver for the brush rolls
Family Handyman weighed the unit at 22.5 pounds, heavy for an upright and awkward to carry up stairs, and the 20-foot cord is short enough that a large room means finding a second outlet. Maintenance is a mixed story: the brush roll cover lifts off and there is a catch tray for debris, but the brush rolls themselves need a screwdriver to remove, which is more friction than a consumer machine should ask of its owner. The controls themselves are straightforward, with an LED mode display on the handle.
A specialist tool at a generalist price
Reader's Digest rated the machine 4.5 out of 5 and Family Handyman 4 out of 5, and both frame it the same way - strong on pet accidents and set-in stains, unremarkable elsewhere. Vacuum Wars also rated it 4 out of 5 without placing it among its top picks, for consistent reasons: the water consumption, the wetness and the weight are costs paid on every clean, while the steam advantage only shows up on the stains that need it. If your carpets mostly need routine refreshing rather than rescue, a machine with better extraction is the smarter buy.

How it compares
The Bissell Revolution HydroSteam 4120 outperforms the Bissell TurboClean Pet XL 3746 in stain cleaning, particularly with syrup stains, thanks to its steam technology. However, it leaves carpets wetter and requires more frequent tank refills compared to the Shark CarpetXpert EX151, which has better suction but worse stain performance.
