This electric sponge works great for cleaning all grouts from tile and stone surfaces (sanded, unsanded, and epoxy based grout). One person can clean 800 to 1500 square feet per hour. This machine leaves all the joints evenly full and cleans the surface with just one pass. You will use one third less water on the jobsite because the sponge rotates through a water sump and is cleaned before contacting the floor again.

•    Made of die cast aluminum which reduces weight while increasing overall strength
•    Control the moisture level of the sponge roller with the pressure adjustment lever
