An automatically movable cleaning device, in particular an electric-motor-driven vacuuming and/or wiping robot, comprising a distance-measuring device for measuring the distance of the cleaning device from an object, wherein the distance-measuring device has an optical triangulation system, which has a light source, an optical filter, and a detector, which are arranged in such a way that light in a propagation direction, emitted by the light source, is first scattered by the object, wherein at least a portion of the scattered light is then spectrally filtered by means of the optical filter and wherein the filtered light is finally detected by the detector. For advantageous development, the optical filter according to the invention is a band-stop filter having a reflectivity of at least 90% with respect to at least one wavelength of the scattered light, and/or the optical filter is a band-pass filter, a reflector being arranged after the band-pass filter in the transmission direction, and/or the optical filter is a cut-off filter having a reflectivity of at least 90% with respect to at least one wavelength of the scattered light.

An upright vacuum cleaner with one or more features, such as a top opening rigid container, a headlight, a replaceable power cord a motor housing suspended within the vacuum to reduce noise and/or vibration a clutch assembly with a RPM sensor, and/or one or more filter plates to improve airflow.

A pool cleaner for cleaning a swimming pool has a vacuum head having an intake nozzle drawing in fluid. A body chamber is coupled to the intake nozzle and has an intake end and a discharge end. A pump is housed within the body chamber drawing fluid from the intake end and expelling the fluid through the discharge end. A filter is placed within the body chamber filtering out particulates from the fluid drawn into the body chamber. A battery pack is located remote from the pool cleaner and wearable by a user of the pool cleaner. A power cord couples the battery pack to the pump. The power cord being electrically connected to the pump by a waterproof connector.

An autonomous mobile robot includes a body, a drive supporting the body above a floor surface, a light-propagating plate positioned on the body and having a periphery defining a continuous loop, light sources each being positioned to direct light through a portion of the plate to a portion of the continuous loop, and a controller to selectively operate the light sources to provide a visual indicator of a status or service condition of the autonomous mobile robot. The drive is configured to maneuver the mobile robot about the floor surface.

There is provided a cleaning robot including a light source module, an image sensor and a processor. The light source module projects a line pattern and a speckle pattern toward a moving direction. The image sensor captures an image of the line pattern and an image of the speckle pattern. The processor calculates one-dimensional depth information according to the image of the line pattern and calculates two-dimensional depth information according to the image of the speckle pattern.

An automatic guiding method for a self-propelled apparatus (10) is provided. The self-propelled apparatus (10) turns and irradiates when a signal light emitted by a charging dock (20) is sensed by a flank sensor (103), and changes its turn direction when another different signal light from the charging dock (20) is sensed by a forward sensor (102). The charging dock (20) switches to emit another signal light different from the signal light currently emitted when each time is triggered by the signal light emitted by the self-propelled apparatus (10). Repeatedly execute the above actions and make the self-propelled apparatus approach the light-emitting unit (202) until the self-propelled apparatus (10) reaches a charging position. It can accurately guide the self-propelled apparatus (10) to the charging position by arranging only two sensors on the self-propelled apparatus.
