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.

There is provided a robot including a first light source, a second light source, an image sensor and a processor. The processor is used to calculate an image quality of an image frame captured by the image sensor when the second light source is being turned on. The processor then determines whether to switch the second light source back to the first light source according to the image quality to accordingly identify the material of an operation surface.

The present disclosure provides a surface cleaning apparatus that includes a headlight or other light source that selectively illuminates upon the occurrence of a predetermined condition. The headlight turns on to emit light when the surface cleaning apparatus us turned on, and emits light in a different color when cleaning fluid is dispensed. Methods for operating a headlight or light source are also disclosed.

There is provided a moving robot including a first light source module and a second light source module respectively project a first light section and a second light section, which are vertical light sections, in front of a moving direction, wherein the first light section and the second light section cross with each other at a predetermined distance in front of the moving robot so as to eliminate a detection dead zone between the first light source module and the second light source module in front of the moving robot to avoid collision with an object during operation.

A nozzle device intended for use in a cleaning appliance such as a vacuum cleaner is described. The nozzle device can be moved over a surface to be cleaned. The nozzle device includes at least one light-emitting source arranged at a side of the nozzle device, and the at least one light-emitting source emits light from the respective side of the nozzle device. The nozzle device further includes a controlling arrangement for varying, at least one parameter of the at least one light-emitting source in relation to actual circumstances of a cleaning action between a functional value and at least one default value which is different from the functional value, and for setting the functional value of the parameter when the respective side is in the vicinity of an obstacle on the surface to be cleaned.
