Abstract: A method for operating a floor cleaning machine on a floor surface. The floor cleaning machine includes a cleaning-liquid container, a dirty-liquid container, a chassis for moving the floor cleaning machine over the floor surface, a cleaning means and a dirty-liquid take-up means. The method includes: sensing an amount of cleaning liquid supplied from the cleaning-liquid tank to the cleaning means within a first time interval while moving the floor cleaning machine; sensing an amount of dirty liquid being removed from the dirty-liquid take-up means to the dirty-liquid container within a second time interval while moving the floor cleaning machine; comparing the sensed amount of cleaning liquid against a first threshold value; comparing the sensed amount of dirty liquid against a second threshold value; outputting a first fault signal if the sensed amount of cleaning liquid is greater than the first threshold value and the sensed amount of dirty liquid is less than the second threshold value.

Abstract: A mobile cleaning robot can include a body, a drive wheel, and a wheel stop. The drive wheel can be connected to the body and can be operable to move the mobile cleaning robot about an environment. The wheel stop can be movable with respect to the body and the drive wheel between a stop position and a release position. The wheel stop can be engageable with the drive wheel in the stop position to limit vertical travel of the drive wheel with respect to the body.

Abstract: The present disclosure discloses a method for controlling cleaning based on dense obstacles. The method includes: step 1, marking dense obstacle points according to a number feature of grids of obstacles framed by a sliding rectangular frame which is preset in a grid map, and then proceeding to step 2; the step 2, planning navigation paths of which an end point position is corresponding to one dense obstacle point and which does not pass grids of other obstacles, and then proceeding to step 3; and the step 3, controlling the cleaning robot to complete traveling a circle around an obstacle currently in collision in a process of navigating the cleaning robot to an actual position corresponding to each of the dense obstacle points according to the navigation paths planned in the step 2, and marking a cleaning state of a grid corresponding to the obstacle currently in collision.

Abstract: A robotic cleaner may include a chassis, an agitator assembly configured to engage a surface to be cleaned, and a lift mechanism moveably coupling the agitator assembly to the chassis. The lift mechanism may include a biasing mechanism. The biasing mechanism may be configured to generate a biasing force that urges the agitator assembly in a direction away from the surface to be cleaned. The biasing force may be insufficient to lift the agitator assembly from the surface to be cleaned.
