The compact scrubber drier B 50 W Bp impresses with its extremely robust design. The brush head and squeegee are made of durable die-cast aluminum - for excellent suction even on structured surfaces and in tight curves. The single-disc brush head D 51 reliably ensures the best cleaning results as well as quiet maintenance or interim cleaning. An 80 Ah lithium-ion battery enables the trailer machine to have a long service life. Thanks to the quick charging function, unnecessary charging times are shortened and long downtimes are reduced. The compact design provides a better overview and manoeuvrability. The wheel drive makes operation easier and reduces physical exertion. A new "Dose" dosing system also helps with the exact dosing of cleaning agents - this saves costs and resources. The auto-rinse function enables contact-free dirty water tank cleaning. Universal hose and auto-fill system help to easily fill the fresh water tank with a stop function at every tap. Thanks to the “Machine Connect” app, advanced settings and information can also be conveniently accessed via smartphone.
