The high performance turbine ensures high suction power and high vacuum. This results in an excellent suction result Constant high suction power by running automatic cleaning of the filter The flat-folding filter with Teflon/nano coating enables an optimal use of the container volume With permanent socket and electronic on/off automatic control The volume flow control via the rotary switch reduces a possible vacuum on the surface with coating between- and fine grinding For wet suction: With electronic level monitoring Start-up delay prevents voltage peaks during start-up and switch-off delay (15 seconds follow-up) empties dust residues in the suction hose Double-walled, stable container with integrated grip recess for easy emptying of the container Equipped with large wheels and two swiveling castors made of metal Separate engine air cooling channel with coarse dirt filter. Protects the turbine against feed of ambient air and thus increases the lifespan. (Fine dust filter PES available
