Are carpet cleaners with built-in heat or steam worth the extra money?

Heated and HydroSteam models such as the Bissell ProHeat and Revolution lines carry noticeably higher prices, and their customer ratings (around 4.2 to 4.4) sit slightly below some cheaper non-heated units. Reviewers value faster dry times, but the rating data doesn't show a clear satisfaction premium that justifies the cost for every buyer, so the upgrade makes the most sense for pet households and heavy stain duty.
