The motor defines a motor rotational axis. The handheld vacuum cleaner also includes a cyclonic chamber positioned in the fluid flow path. The cyclonic chamber defines a separator axis. The separator axis and the motor rotational axis form an obtuse angle extending between the cyclonic chamber and the motor assembly. The handheld vacuum cleaner further includes a pre-motor filter in the fluid flow path downstream from the cyclonic chamber and upstream from the motor assembly, a plenum in the fluid flow path immediately upstream from the motor assembly, and a sensor positioned on the plenum. The sensor is operable to measure a characteristic of the fluid flow path.

A suction device with a suction device housing (20), in which a suction turbine (11) for generating a suction flow (S) is arranged, the suction turbine (11) having a suction turbine inflow opening (11A), through which the suction flow (S) can flow into the suction turbine (11) and at least one suction turbine outflow opening (11B), through which the suction flow (S) can flow out of the suction turbine (11), wherein the suction device housing (20) has a suction inlet (12) for letting in the suction flow (S) and a dust collecting chamber (21) for collecting dust contained in the suction flow (S), wherein a filter element (13) for retaining dust in the dust collecting chamber (21) is arranged between the dust collecting chamber (21) and a suction turbine inflow opening (11A) of the suction turbine (11). The suction turbine inflow opening (11A) of the suction turbine (11) is connected to at least one cooling air duct (99, 100, 101), which has a duct inflow opening (97A, 98A, 102) through which cooling air (KL) from an area surrounding the suction device (10) can flow past the filter element (13) to the suction turbine (11).

An autonomous coverage robot includes a cleaning assembly having forward roller and rearward rollers counter-rotating with respect to each other. The rollers are arranged to substantially maintain a cross sectional area between the two rollers yet permitting collapsing therebetween as large debris is passed. Each roller includes a resilient elastomer outer tube and a partially air-occupied inner resilient core configured to bias the outer tube to rebound. The core includes a hub and resilient spokes extending between the inner surface of the outer tube and the hub. The spokes suspend the outer tube to float about the hub and transfer torque from the hub to the outer tube while allowing the outer tube to momentarily deform or move offset from the hub during impact with debris larger than the cross sectional area between the two rollers.

A method for operating a base station for a cleaning device is proposed, wherein exclusively by means of a pressure sensor and/or by means of a differential pressure the filling level of the container is determined as state of the base station and additionally at least one further state of the base station is determined and/or wherein on reaching a predefined filling level the maximum number of still possible extraction processes with-out emptying a container is limited.

A method for operating a vacuum cleaning appliance, having a filter element, a filter element cleaning device, a control device, a turbine, a first pressure sensor and a second pressure sensor. The method includes operating the vacuum cleaning appliance to suck in the air stream through the filter element; determining a first pressure reference value; measuring the pressure difference between the first and second pressure values; dedusting the filter element with the aid of the filter element cleaning device if the value of the pressure difference between the first and second pressure values reaches a first threshold value; determining a second pressure reference value after the end of the dedusting of the filter element; determining a difference value between the second and first pressure reference values; and dedusting the filter element if the difference value between the second and first pressure reference values reaches a second threshold value, or switching off the vacuum cleaning appliance if the difference value between the second and first pressure reference values reaches a third threshold value. A vacuum cleaning appliance for carrying out the method.

A retractable sanitizing apparatus for a vehicle including a return station, a sanitizing mechanism positionable between a first sanitizing position, a second sanitizing position, and a stowed position, the sanitizing mechanism positioned at the return station when in the stowed position, and a linkage member connecting the sanitizing mechanism to the return station and positioning the sanitizing mechanism between the first sanitizing position and the second sanitizing position, wherein the sanitizing mechanism sanitizes a surface of the vehicle as the sanitizing mechanism moves from the first sanitizing position to the second sanitizing position and across the surface of the vehicle.

A suction device and a suction force adjustment method thereof are provided. A detecting device collects sound generated when the suction device executes a suction operation to obtain characteristics of a sound signal. The detecting device determines a clogging degree of a filter disposed on an exhaust vent of a suction unit, an airflow velocity in a suction pipe, a material of the suctioned surface, and a degree of closure between a suction port of the suction device and the suctioned surface according to the characteristics of the sound signal.
