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 cast aluminium – for excellent suction even on structured surfaces and in tight bends. The D 51 single-disc brush head reliably delivers outstanding cleaning and quiet maintenance or intermediate cleaning. The 80 Ah lithium-ion battery enables a long operating time of the walk-behind machine. The quick-charge function reduces unnecessary charging times and long downtimes. The compact design provides a better overview and manoeuvrability. The wheel drive facilitates operation and reduces the physical strain. The new DOSE dosing system also helps to precisely dose cleaning agents. The auto-rinse function enables contact-free cleaning of the dirty water tank. The universal hose and auto-fill system facilitate easy filling of the fresh water tank at any tap with a built-in stop function. In addition, advanced settings and information can be easily accessed from your smartphone thanks to the "Machine connect" app.
