AI Technical Summary
Technical Problem
Floor cleaning devices with rotating brushes pose safety risks when the nozzle is lifted, as they can suck in fingers, hair, or clothing, and existing solutions like stopping or reducing motor speed compromise cleaning performance and motor life.
Method used
A controller that detects whether the nozzle is in contact with the floor or lifted, adjusting the torque threshold of the brush motor to prevent injury without stopping or significantly reducing speed, ensuring safe operation and maintaining cleaning efficiency.
Benefits of technology
Enhances safety by preventing injuries from the rotating brush while maintaining cleaning performance by dynamically adjusting torque limits based on nozzle position, reducing strain on the motor, and avoiding frequent start-stop cycles.
