Karcher BR 30/4 C Autoscrubber

Karcher BR 30/4 C Autoscrubber in use

The Kärcher BR 30/4 features an upright design for maneuverablity similar to an upright vacuum. 10x contact pressure with the floor combined with a brush that spins at 1,500 RPM gives the BR 30/4 much more cleaning power than a mop. For very sticky dirt, the squeegees can be lifted with a foot pedal. Chemicals have more time to react, for better overall cleaning. Hard to reach areas (e.g., under furniture) are no problem thanks to the very low brush head.
