The compact KM 90/60 R ride-on vacuum sweeper is ideal for thorough outdoor cleaning. It is very easy and convenient to operate, and generates almost no dust. Vacuum suction can be varied in wet weather to protect the washable filter from moisture. A rotary switch is used to select the travel, main roller brush, and side broom functions. The unit`s travel speed is infinitely variable up to 8 km/h, and it can climb slopes of up to 18% with ease. It works on the overthrow principle, so the waste containers (consisting of two 30-litre-capacity bins) can be filled to the top.
