The bigger the tank, the more water it can carry and the longer it can run before needing a refill. A small 200ml tank might only clean one or two rooms, while a 750ml tank could clean an entire ground floor without refilling.What happens if the water tank is too small for your home?

If you have a small flat with hard flooring and a 200ml tank, your robot might need to return home three or four times during a single cleaning session, leading to more stops and longer overall cleaning time.
