摘要： A vacuum cleaner includes a housing incorporating a handle assembly and a nozzle assembly, a suction fan and cooperating suction fan drive motor carried on the housing, a rotary agitator held in the nozzle assembly, an agitator drive motor carried on the housing and a motor control and protection circuit. The motor control and protection circuit includes a handle switch to de-energize the agitator motor when the handle is displaced to an upright storage position. The motor control and protection circuit may also include an above-floor switch and cooperating activation to de-energize the agitator drive motor when the nozzle assembly is displaced above the floor for bare floor cleaning. Additionally, the motor control and protection circuit may include a hose switch and activator, a selection switch and activator, a circuit breaker and a temperature sensor switch.

摘要： 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 the 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 which the housing can be displaced over the surface, and an electrical control unit (17) for controlling a displacement of the housing generated by the wheel system. According to the invention, the displacement of the housing controlled by the control unit (17) includes 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, the 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.

摘要： An electric vacuum cleaner including a motor-driven blower driven by an inverter circuit. The inverter circuit has a plurality of switching elements. The inverter circuit AC-drives a motor-driven blower according to periodic switching between the switching elements. The periodic switching is based on the detected value of physical quantities related to the electric vacuum cleaner. The electric vacuum cleaner can, in the highest operation mode, undergo a sudden fluid load variation. The electric vacuum cleaner is able to limit, by way of the inverter circuit, the unpleasant sound produced by the vacuum cleaner due to the change in rotation velocity of a rotor of a motor of the vacuum cleaner.
