Product information and benefits

The B 50 W Bp compact scrubber dryer boasts a particularly robust design. The brush head and squeegee are made from long-lasting cast aluminium – for excellent suction even on structured surfaces and in tight bends. The R 55 brush head with integrated sweeping functions reliably ensures optimum cleaning results and clean floors.
