3 Things to Know About Mopping Robots and Water Tanks

Cheaper mopping robots use a single water tank that drips onto the pad without rinsing it. This means the mop gets dirtier with every pass across your floor.

Models with separate clean and dirty water tanks wash the pad as they go. They scrub with fresh water each time instead of spreading dirty water around.

The difference is a wet rag dragged across your floor versus an actual mop that cleans itself. Separate tanks are worth the extra cost for effective mopping.
