The Raimondi Berta ADV Sponge Machine is a professional-grade cleaning tool engineered for fast, dust-free removal of cement or epoxy grout on tile, stone, marble, and porcelain floors. Its powerful yet smooth operation handles large areas with ease, cleaning up to 100 m²/hour on medium-difficulty surfaces and up to 1500 ft²/hour on smoother ones .

Built from lightweight aluminum with a foldable ergonomic handle, this machine is easy to manoeuvre. It features a large water tank and pressure-adjustable front wheels to regulate sponge moisture—designed to clean grout without pulling it from joints. Swapping sponges is seamless via a magnetic clutch, and its compact design fits into tight spaces.

Perfect for tilers, builders, or landscapers, the Berta ADV simplifies post-grout clean-up by reducing water use, enhancing cleaning efficiency, and preserving grout integrity.
