AUTOMATICALLY DISPLACEABLE FLOOR-DUST COLLECTOR

摘要

The invention relates to an automatically displaceable floor-dust collector (1) which comprises an electromotive drive, a dust collection container and a cover (3). The collector (1) comprises one or more driven wheels (7) and one non-driven, travelling passive wheel (8). Measures can be initiated for regaining free mobility of the collector (1) when the collector (1) detects an obstacle to its free mobility. The aim of the invention is to improve the device of the aforementioned kind in such a manner that it always remains mobile. For this purpose, the passive wheel (8) is monitored for its movement and a measure is initiated when the intensity of movement of the passive wheel (8) changes.
