Floor drying or wetness was a weakness in one mopping review, especially on the wettest settings.

Wet-spill tests left floors dry enough that one reviewer found no visible dampness after cleaning.

The single-roller floorhead did not appear to harm dust collection in one review, though evidence was limited.

The main roller/floorhead design is a rare weak point because hair pickup did not fully satisfy one tester.

The mop can leave floors shiny after routine cleaning.

Fresh liquid pickup was generally positive for spills and sticky liquids, although one reviewer said manual cleanup can be faster for urgent spots.

Fresh wet spills were handled very well, with little sign left after the robot cleaned.

Hair-removal channel issues were addressed well by the TriCut brush preventing suction-tube blockage.

Hair can collect in a crevice near the wheelbase, though removal was manageable.

Carpet hair pickup was mixed, from one poor lab-style pet-hair result to strong real-world pet-hair praise.

Carpet hair pickup is weak relative to the product's price, with only about half of test hair collected.

Hard-floor hair pickup was praised in a pet-heavy home.

General hair pickup is acceptable to good in some reviews, but it is not consistently excellent.

Hair-wrap resistance was mixed: the stock brush struggled in one test, while the TriCut brush and later reviews were positive.

Hair-wrap resistance is mixed: standard brushes can tangle, but anti-tangle design and optional accessories reduce maintenance.

Hard-floor fine dust pickup was strong, with reviewers praising clean tile and efficient dust pickup.

Hard-floor fine-debris pickup is consistently strong, with only minor misses in some tests.

Large hard-floor debris pickup was mixed, with strong crumb pickup in one review and dry-oat scattering or big-debris avoidance in others.

Large hard-floor debris intake is strong overall, despite occasional missed cereal pieces.

Hot water and heated drying were viewed as meaningful cleaning advantages rather than mere extras.

Hot-water cleaning and heated drying are viewed as useful for mop hygiene and maintenance.
