CLEANING DEVICE FOR CLEANING ARTIFICIAL FLOOR AREAS PROVIDED WITH FLOOR COVERING PARTICLES, ESPECIALLY FOR ARTIFICAL TURF
First Claim
1. A cleaning device for cleaning artificial floor coverings provided with floor covering particles, comprising:
- a sweeping device configured to gather dirt particles from the floor covering;
a separation device configured to separate the dirt particles from floor covering particles;
a floor covering particle feedback device configured to feed back to the floor the floor covering particles separated from the dirt particles by the separation device;
a filter device configured to filter dust particles; and
a suction device configured to draw air from the area of the separation device through the filter device;
the cleaning device comprising a first negative-pressure chamber and a second negative-pressure chamber, in which a negative pressure can be formed by the suction of the suction device, the first negative-pressure chamber being formed above the separation device;
the first and the second negative-pressure chambers being in fluid communication through the separation device;
the second negative-pressure chamber being formed below the separation device; and
the first negative-pressure chamber being in fluid communication with the suction device only via the second negative-pressure chamber, to draw air from the second negative-pressure chamber by the suction device and to draw air from the first negative-pressure chamber via the second negative-pressure chamber.

Abstract
A cleaning device for cleaning artificial floor coverings provided with floor covering particles, such as artificial turf, comprising a sweeping device for gathering dirt particles from the floor covering, a separation device for separating the dirt particles from floor covering particles, a floor covering particle feedback device for gathering the floor covering particles separated from the dirt particles and feeding back the floor covering particles to the floor, a filter device for filtering dust particles, and a suction device which draws air from the area of the separation device through the filter device. First and second negative-pressure chambers in which negative pressure can be formed by the suction device suction are formed above and below the separation device, respectively, in fluid communication through the separation device. The first negative-pressure chamber is in fluid communication with the suction device only via the second negative-pressure chamber.
