1. A self-propelled device for vacuum cleaning of an underlying surface, comprising:
- a cleaner body supported for movement on the underlying surface and including a base member;
driving means on said body for rotation of said body at a fixed surface location and for substantially straight-line movement of said body on and along the underlying surface;
means for wireless remote-controlled operation of said driving means to cause said driving means to selectively switch between stationary rotation and substantially straight-line movement of said cleaner body on receipt of a radio control signal;
vacuum means on said body for suction cleaning of the surface underlying said cleaner body, said vacuum means comprising a suction fan for drawing dirt into the cleaner body, a filter removably supported on said base member for collecting the dust drawn into the body, and an inlet port defined in said base and open in the direction of the underlying surface for dirt drawn from the surface to the interior of said cleaner body through the inlet port for collection in the filter;
battery means on said body for powering said driving means; and
manual switch means on said cleaner body for connecting said battery means to and providing operating power for said driving means, said suction fan being powered by and connected to said battery means through said manual switch means.

Abstract
A self-propelled cleaning device with wireless remote control includes a body, a driving device on the body for moving the same rotatably about its axis or in a straight line along the underlying ground surface, and a vacuum cleaning device carried on the body with its suction port open to the underside thereof. The cleaning device normally rotates on its axis at a stationary or fixed location on the underlying surface for concentrated spot cleaning of the underlying surface. The wireless remote control is effective to change the operative mode of the cleaning device from stationary rotation to straight-line travel.

10. A self-propelled vacuum cleaner device for supported movement on and along an underlying surface, comprising:
-
a body; drive means on said body and including a pair of substantially parallel wheels supporting said body on said surface and arranged for rotation with respect to said body, an electric motor rotatable in normal and reverse directions, a battery for powering said motor, an electronic contol circuit for causing reverse rotation of the motor in response to a radio control signal, and power transmitting means for transmitting the rotation of said motor to said wheels so as to rotatively drive the same such that one of said wheels is driven in either a forward or a reverse rotational direction depending upon the direction of motor rotation while the other said wheel is driven in said forward rotational direction irrespective of the direction of motor rotation, said wheels being thus driven in relatively opposite directions in the absence of a radio control signal whereby said body is caused to rotate at a substantially stationary location on the underlying surface, and said wheels being driven in the same direction in response to a radio control signal for substantially straight-line movement of said body along the surface; vacuum cleaning means on said body and including a suction port to serve as an inlet for dust and open in the direction of the underlying surface, a suction fan, a suction motor for driving said fan to draw dust from the surface into said body through said port, and a filter for collecting dust drawn into said body by the action of said motor-driven suction fan; and manual switch means rotatable in a first direction for operating said electric motor, movable in a second direction for operating said suction motor, and rotatable in a third direction opposite said first direction for disengaging said switch means to terminate operation of said electric and suction motors, said switch means being located on said body at the center of stationary rotation thereof for facilitated manual user access to said switch means during said substantially stationary rotation of the body.
