Sponge-machine for cleaning grout (cement based or epoxy resin) from floors: terracotta, porcelain, double-fired and single-fired tiles, marble, porphyry, natural stone, quarry tile, treaded tile, etc. during the grouting phase.

• Performance: 100 sq m/h for medium difficulty surfaces (800 - 1 500 s.f. per hour in general)
• Sponge rollers can last from 150 to 2 000 sq m (1 600 - 21 000 s.f.). • Water is fed to the roller via a foam-reducing rubber belt. So, no pump is needed resulting in no clog up.
• Does not pull grout from the joints
