Abstract (en)
[origin: WO2020163336A1] A cleaning system (100) including a body (105), a motor (140) supported by the body (100), a sensor (325) configured to sense a characteristic of the motor (140), the characteristic selected from a group consisting of current, voltage, and power. The system (100) further includes a controller (305). The controller (305) is connected to the motor 140 and the sensor (325). The controller (305) includes an electronic processor (330) and a memory (335). The controller (305) is configured to receive, from the sensor (325), a signal indicative of the characteristic of the motor (140), determine, based on the signal, an integral of the signal over time, and operate the motor (140) based on the integral of the signal over time.
