An autonomous floor-cleaning robot comprising a housing infrastructure including a chassis, a power subsystem; for providing the energy to power the autonomous floor-cleaning robot, a motive subsystem operative to propel the autonomous floor-cleaning robot for cleaning operations, a command and control subsystem operative to control the autonomous floor-cleaning robot to effect cleaning operations, and a self-adjusting cleaning head subsystem that includes a deck mounted in pivotal combination with the chassis, a brush assembly mounted in combination with the deck and powered by the motive subsystem to sweep up particulates during cleaning operations, a vacuum assembly disposed in combination with the deck and powered by the motive subsystem to ingest particulates during cleaning operations, and a deck adjusting subassembly mounted in combination with the motive subsystem for the brush assembly, the deck, and the chassis that is automatically operative in response to an increase in brush torque in said brush assembly to pivot the deck with respect to said chassis. The autonomous floor-cleaning robot also includes a side brush assembly mounted in combination with the chassis and powered by the motive subsystem to entrain particulates outside the periphery of the housing infrastructure and to direct such particulates towards the self-adjusting cleaning head subsystem.

A robot cleaner system having an improved docking structure between a robot cleaner and a docking station, which is capable of an easy docking operation of the robot cleaner and preventing loss of a suction force generated in the docking station. The robot cleaner includes a docking portion to be inserted into a dust suction hole of the docking station upon a docking operation. The docking portion may be a protrusion, which protrudes out of a robot body to be inserted into a dust suction path defined in the docking station, the protrusion communicates a dust discharge hole of the robot cleaner with the dust suction path of the docking station. The robot cleaner system includes a coupling device to keep the robot cleaner and the docking station in their docked state. The coupling device is configured to have a variety of shapes.

The invention relates to a method for operating a floor cleaning system having a central suction station with which there is associated a self-propelled and self-steering suction appliance, dirt being picked up from a floor surface that is to be cleaned by means of the suction appliance and being transferred into a dirt collection vessel of the suction appliance, and the suction station having a suction unit, and the dirt collection vessel being sucked out by means of the suction unit. To refine the method in such a manner that the levels of noise produced by the floor cleaning system can be reduced, it is proposed, according to the invention, that the suction unit is optionally operated with a maximum suction power or a reduced suction power. The invention also proposes a floor cleaning system for carrying out the method.

A dust-collectable mobile robotic vacuum cleaner includes a base frame, a driving device mounted to the base frame, a control device mounted to the base frame and electrically connected with the driving device, a collision-detectable unit mounted to the base frame electrically connected with the control device, and a dust-collecting device mounted to the base frame. The dust-collecting device has dust-collecting box, a dust guider, a round brush, and a dust entrance formed at one side of the dust-collecting box. The dust guider is located at a lower edge of the dust entrance, having two opposite sides pivotably mounted to the dust-collecting box and lying against the ground at a predetermined angle respectively, for upward and downward pivoting movement. The round brush is rotatably located at a front end of the dust guider for sweeping dust particles.

A robot cleaning system and a dust removing method of the same that are capable of moving a first dust collector mounted in a robot cleaner to a docking station to remove dust collected in the first dust collector. The robot cleaning system includes a robot cleaner having an opening, though which a first dust collector to collect suctioned dust is carried in and out of the robot cleaner, a docking station, to which the robot cleaner is docked to remove the dust collected in the first dust collector, and a collector moving unit to move the first dust collector to the docking station.
