Raimondi Berta Electric Grout Sponge Machine for cleaning grout (cement-based or epoxy resin) for large and small grouting installations including ceramic, porcelain quarry, brick, and stone. Does not pull grout from the joints. Suitable for use even in small areas processing 800 - 1500 s.f. per hour. 3 replacement sponge types are available, sanded & unsanded grout, unsanded, and epoxy. Sponge rollers live 1,600 to 10,000 s.f. The moisture level of the sponge roller is adjusted by the pressure adjustment lever. The pressure adjustment lever also adjusts the front wheels. Easy-to-replace sponge roller thanks to the magnetic “quick clutch” system. Water is fed to the roller via a foam-reducing belt (no pump to clog up). The handle folds down for transport or storage, and its ergonomic design is fully adjustable for height and angle according to the user(s) needs. Die-cast aluminum body reduces weight while increasing overall strength. Easy-to-remove water tank (15 liters, 4 gals.) is made of impact-resistant plastic to reduce breakage. Raimondi Berta Electric Grout Sponge Machine is supplied with a standard sponge roller for cement-based grout, anti-foaming liquid, user, and maintenance manual. Free Shipping to a commercial address.
