Abstract
The present invention relates to a controller for controlling a floor cleaning device that comprises a nozzle configured to contact a floor, a rotatable brush arranged at the nozzle, a brush motor configured to drive the brush to rotation, and a nozzle detector configured to detect whether the nozzle contacts the floor or is lifted from the floor. The controller being configured to control the rotation of the brush by means of the brush motor; and to decrease an upper threshold of a parameter related to a torque of the brush motor, if the nozzle detector detects that the nozzle is lifted from the floor.
Claims13
A controller for controlling a floor cleaning device that comprises a nozzle configured to contact a floor, a rotatable brush arranged at the nozzle, a brush motor configured to drive the brush to rotation, and a nozzle detector configured to detect whether the nozzle is lifted from the floor,
- the controller being configured to:
- provide control signals to the brush motor to control the rotation of the brush;
- receive sensor data from the nozzle detector that indicates whether the nozzle is lifted from the floor;
- control the control signals to decrease an upper threshold of a parameter related to a torque of the brush motor, based on the sensor data indicating that the nozzle is lifted from the floor, to decrease a maximum current or voltage drawn by the brush motor.
