A cleaning robot is provided. The cleaning robot includes a body, a light detection and ranging (LiDAR) module having a LiDAR sensor rotatably supported by the body, a light-emitting display module mounted on the LiDAR module, wherein the light-emitting display module is configured to display an image based on an afterimage effect according to a rotation of the LiDAR module.

A vacuum cleaner includes a vacuum body defining an agitation chamber, an agitator, and an illumination system. The agitator is rotatably disposed at least partially within the agitation chamber and includes an agitator body defining an illumination chamber. The illumination system is at least partially disposed within the illumination chamber and includes at least one light source. Alternatively, a vacuum cleaner includes a vacuum body defining an agitation chamber, an agitator rotatably disposed at least partially within the agitation chamber, an illumination coupled to the vacuum body and including at least one light source, and a light guide configured to redirect light emitted in a first direction from the at least one light source to a second direction.

The present disclosure provides a method for expanding a working area based on a laser map, a chip and a robot, and the method for expanding the working area includes using map pixel point information obtained by laser scanning to position pending boundary lines, deciding a next expansion of a rectangular working area according to an increment of a diagonal length of the rectangular working area framed by the pending boundary lines in a current expansion process, stopping expanding the rectangular working area of the robot when the increment of the diagonal length before expanding and after expanding reaches an overlap condition.

A surface treatment apparatus may include a coupling, a handle, an accessory coupled to the coupling, and a toggle proximate the handle. The accessory may have at least two operational states. An actuation of the toggle may cause the accessory to transition between operational states.

A cleaning system for swimming pools and spas may include an automatic swimming pool cleaner and an anti-theft system for the automatic swimming pool cleaner. In some cases, the anti-theft system may be an active system generating an active response based on a safety situation. Additionally or alternatively, the anti-theft system may provide increased prevention and/or deterrence to theft.

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

A cleaning apparatus including a vacuum cleaner and a docking station is provided. The cleaning apparatus includes a vacuum cleaner including a dust collecting chamber in which foreign substances are collected, and a docking station configured to be connected to the dust collecting chamber to remove the foreign substances collected in the dust collecting chamber. The dust collecting chamber is configured to collect foreign substances through centrifugation, and configured to be docked to the docking station, and the docking station includes a suction device configured to suction the foreign substances and air in the dust collecting chamber docked to the docking station.
