The base with SUPERPRO sponge is a float with SWEEPEX® sponge specially designed to be used with the RUBICLEAN PLUS SUPERPRO washboy (ref. 20916). The structure of the base with pad is reinforced and has a sponge fastening system with 6 screws. The SWEEPEX® sponge float has a large work surface (34 cm x 17 cm) and a considerable thickness of 5 cm, ideal for working on large floors. The SWEEPEX® sponge float is made of flexible polyester-based polyurethane; it has a high level of absorption and excellent abrasion resistance, being ideal for cleaning all surfaces, especially the coarsest ones. Moreover, owing to its size and the fact that it is specially designed for work standing up, owing to the aluminium handle with "soft" grip, it is perfect for cleaning large floors, especially during the grouting process. Its use with acid-based products is not recommended. The SWEEPEX® replacement sponge for the SUPERPRO sponge with base for washboy is very easy to install - the user only has to remove the 6 screws from the base and replace the old sponge for the new spare part.
