Berta Electric Sponge Machine - Raimondi


Raimondi's Berta Electric Sponge Machine is used to clean all grout from stone and tile floors (unsanded, sanded, and epoxy based grout). Machine cleans 800 to 1500 square feet per hour making it great for cleaning grout in medium to large areas. Leaves all joints equally full, and cleans the surface with one pass without pulling grout from joints. Uses 1/3 less water on the job site, saving you the hassle of going to get fresh water and making the job more efficient.

There are three different replacement sponges for the Berta Electric Sponge Machine. The Avana (Brown) Sponge Roller for sanded and unsanded grout, Cellulose Sponge Roller for epoxy grout, and Sweepex (Yellow) Sponge Roller for unsanded grout (good for gloss and polished surfaces). Replacement rollers are available but sold separately.
