Embodiment Construction

[0016] figure 1 is a schematic view of an embodiment of the automatic device for vacuuming surfaces according to the present invention, wherein the automatic device comprises a substantially annular cylindrical synthetic resin housing 1 having a central main axis 2 . Housing 1 accommodates an electric suction unit 3 of the type known and commonly used in vacuum cleaners. The suction unit 3 is connected to the suction head 7 through the dust collection chamber 5, and the dust collection chamber 5 is also arranged in the casing 1, and the suction head is equipped near the lower part of the casing 1, so that the suction head is located beside the surface 9 to be dusted during operation . Also housed in the housing 1 are batteries or accumulators 11 for powering the suction unit 3 during operation. The automatic device also includes a motor-driven wheel train 13 whereby the housing 1 including the suction head 7 can be moved on the surface 9 to be dedusted. In the illustrated e...

Abstract

The invention relates to a robot vacuum cleaner for cleaning surfaces (9), which robot vacuum cleaner is provided with a housing (1), a suction unit (3) accommodated in said housing, a suction nozzle (7) mounted to the housing so as to be present near the surface in operation, a motor-drivable wheel system (13) by means of which the housing can be displaced over the surface, and an electrical control unit (17) for controlling a displacement of the housing generated by means of the wheel system. According to the invention, the displacement of the housing controlled by the control unit (17) comprises a substantially cycloid movement brought about by a rolling movement of an imaginary rolling circle (37) along an imaginary line of displacement (39) of the housing over the surface, said imaginary rolling circle extending parallel to the surface (9) and being fixed with respect to the housing (1), and the suction nozzle (7) being eccentrically arranged with respect to the rolling circle. As a result, the width of the track cleaned by the suction nozzle during the displacement of the robot along the line of displacement is considerably larger than the main dimension (WS) of the suction nozzle.

Description

technical field [0001] The invention relates to an automatic device for surface vacuum dust removal. The automatic device has a housing; a suction unit installed in the housing; the position of the surface to be vacuumed; a motor-driven train of wheels by which the housing is movable over the surface to be cleaned; and an electric controller which controls the movement of the housing by the train of wheels. Background technique [0002] Automatic devices of the type described in the preceding paragraph are generally well known. The controller of such an automatic device controls the train of wheels in such a way that the automatic device automatically makes a predetermined or aimless movement over the surface to be cleaned so that after a certain period of time the automatic device reaches and cleans all parts of the surface . Such robots are typically provided with sensors that the controller cooperates to try to avoid obstacles as the robot moves over the surface. The r...
