Our new, powerful, BV 5/1 Bp battery-powered Backpack vacuum is the first choice where narrow spaces hinder cleaning work, whether in cinemas, on planes, buses, trains or even stairs. The clever, ergonomic and patented carrying frame with the Air Stream Comfort system makes for easy handling, reduces heat generation on the back and at the same time prevents unwanted vibration. It can be easily adjusted for different operators and ensures a comfortable fit. Operation of the machine is also convenient, as all the important operating and additional functions such as the eco!efficiency mode or the charging status display, are controlled or monitored directly via the control panel on the waist strap.
