Abstract

A self-propelled means 1 with a large central rotating brush 4 comprises two opposed and extendable devices, parallel to the aforesaid brush, to which the same number of cylindrical helical brushes 17 are fitted and combined with collectors 18 with helical conveyors 19 and suction ducts 21. The helical conveyors 19 communicate both with the central rotating brush 4 and with the dust collection box 9 which is connected with the suction devices 23 through interchangeable filters 22 which could also be fitted with means of shaking. The opposed frontal devices are fitted with independent components 13 which allow their width to be extended beyond the external lateral profile of the motor sweeper. <IMAGE>
