Cons: Noise level
Floor drying time was positive where the robot left a thin, even layer of water that dried quickly.
Pros: Mopping performance, Edge and Baseboard Cleaning (Hard Floors)
Cons: Solution / Liquid system
Floor drying time was positive, with floors drying within minutes or quickly after mopping.
Pros: Overall opinion, Suction and Airflow
Floor drying was good in one review because mopping left little damp residue.
Pros: Mopping performance, Obstacle Avoidance (Robot)
Cons: Hair‑Wrap / Tangle Resistance, Bin and Bag
Floors generally dried quickly after mopping, and the hot-air dryer left the mop pad dry between cleanings.
Pros: Mopping performance, Self-cleaning cycle
