Pros: Assembly and Setup, Floorhead Seal on Hard Floors
Cons: Convertible handheld design, Upholstery / Above-Floor Pickup

Odor control is tied to the air-dry + self-clean routine: reviewers specifically note that keeping the roller from staying wet helps reduce the “stink” that can develop in wet cleaners.

Several reviews warn that odors can develop if the dirty tank is not emptied promptly or if the roller stays damp, so quick post-clean emptying and occasional air-drying are recommended.
