Overview
- The current market now includes MOVA’s Z70 (roller) and V70 (mop-pad), Dreame’s X60 as the tested technical leader, and ECOVACS’ WINBOT W2S PRO OMNI as an award-winning, €599 window-cleaning option.
- Rotating-walze (roller) systems actively pump away dirty water so they remove dried stains in fewer passes, while mop-pad systems are more compact and can reach edges with extendable brushes.
- Suction figures are often prominent in specs but do not determine wiping method because both roller and pad machines can ship with similar Pa ratings.
- Roller systems use more energy and demand more upkeep because the rotating cylinder runs continuously and traps hair and wash-tank residue, whereas mop-pad systems save power but must return frequently to a station that washes and dries pads to prevent odors.
- Buyers should pick by household needs—pets and frequent dried kitchen spills favor rollers, tight layouts and many corners favor mop pads, and station features like 100°C wash, heated drying or battery-powered Omni stations materially affect hygiene, running costs and convenience.
