The M210 Omni uses a roller mop with a real-time fresh-water system, so the surface touching your floor is rinsed while the robot runs. The body is only 85 mm, about 3.35 in, tall and 280 mm wide, which lets it go under sofas that stop most mop stations. A self-cleaning and self-drying base handles the roller afterwards.
It sits at the top of the price ladder here and carries the highest suction label, 20,000 Pa. That is a peak figure, and the roller and brush do more for hard-floor results than the motor does. Compared with the M3 it swaps flat pads for the roller and drops the hot-water wash.
Upkeep centres on the base: wipe the tray, empty the dirty tank, and check the drain for lint after each week of use. The tangle-free roller needs the usual monthly trim, and roller replacements are the main consumable. Over a year of weekly mopping, plan on at least one spare roller and a few filters, and keep the base away from carpet so the drain tray never leaks onto a rug.
