When the cleaning robot is loaded with a new cleaning module, the loaded new cleaning module replaces the old cleaning module originally carried on the cleaning robot, in this way, the assembling and disassembling of the cleaning modules on the cleaning robot can be performed synchronously.

Provided is a robot cleaner including a main body including a suction portion disposed thereon, main wheels for moving the main body, and a side brush assembly disposed on the main body and rotating with a rotation shaft perpendicular to a rotation shaft of the main wheels, the side brush assembly includes a housing for forming an exterior of the side brush assembly, a first force transmitter disposed in the housing and rotating by receiving a driving force, a belt connected to the first force transmitter, a second force transmitter connected to the first force transmitter by the belt to receive a rotational force of the first force transmitter, and a side brush coupled to the second force transmitter.

A vehicle floor mat vacuum machine includes an elongate open mouth communicating with an interior chamber for passage of a floor mat therethrough and between an upper feed roller and a lower brush roller for contacting a carpet surface of the floor mat. A vacuum source connects to a vacuum manifold to create suction, as the brush roller and suction force work in conjunction to remove sand, dirt and other debris from the floor mat. An electric motor, drive belt and reduction gear assembly rotate the feed roller and brush roller in opposite directions with the brush roller rotating at a significantly higher speed. In one embodiment, the vacuum source is a central vacuum system, wherein a solenoid-controlled valve in the vacuum line extending from the feed roller is opened for a timed sequence during operation of the machine.

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.
