Odor control

Best

#4
Hot-water mop washing plus hot-air drying in the dock helps prevent the mop pads from developing musty odors or mildew. The dock and tray self-cleaning features also reduce grime buildup that can cause smells over time.
#5
Heated/warm-air drying and keeping the roller rinsed helps prevent musty smells, though users still need to rinse the dirty tank and keep the wash tray clean to avoid odor buildup.
#6
Self-drying helps prevent the musty-roller smell many vac-mops develop, but reviewers still stress that leaving dirty water sitting in the tank can cause odors, so prompt emptying remains important.
#16
Because the dock doesn't store dirty mop water, it can be less prone to tank odors than self-washing systems; odor control still depends on washing or swapping dirty pads promptly.
#17
The dock canister is designed to conceal debris and some reviews mention odor-sealing touches; certain versions include a scented insert that can add a light fragrance during operation.
#21
Tools can start to smell unpleasant after use if residue is left inside, so rinsing and air-drying parts is important; frequent cleaning of tool covers/inserts helps prevent lingering odors; odor control is primarily driven by maintenance habits.
#23
Odor/off-gassing is rarely mentioned, but one technician review reports a strong plastic smell from the unit, described as unpleasant; other reviews do not emphasize odor issues.
