Product information and benefits

The compact and robust B 50 W Bp floor scrubber is designed for wet cleaning floors and features an O51 orbital brush head, universal filling hose, and app connection. The compact and robust B 50 W Bp floor scrubber is ideal for efficient floor cleaning. Its squeegee and brush head are made of durable die-cast metal or aluminum, ensuring reliable suction results even on textured surfaces and tight corners. The O51 orbital brush head features low vibration and enables the best cleaning results for both daily maintenance and deep cleaning—even in demanding applications. Water consumption is up to 25 percent lower than that of conventional disc brush heads, highlighting its resource-saving operation. Chemical-free cleaning is also possible.
