Patent for Robot Cleaning System with Automatic Mopping Module Replacement Released

A patent for a robot cleaning system that can automatically replace a mopping module has been released, providing a significant advancement in domestic cleaning robots. The system consists of a cleaning robot, a base station, and a control method. The base station is equipped with a storage module, an operating position, and a transfer module, allowing the cleaning robot to dock and replace the mopping module automatically. This innovation addresses a long-standing problem in existing cleaning robots, where users had to manually replace mopping modules, which could lead to a degraded cleaning effect and contamination of the cleaned ground.

Key Takeaways:

  • The patent describes a robot cleaning system that can automatically replace a mopping module, eliminating the need for manual intervention.
  • The base station includes a storage module, an operating position, and a transfer module, allowing for seamless replacement of mopping modules.
  • The system uses a control unit to control the connection assembly to mount and/or unload a corresponding mopping module at the operating position.
  • The operating position includes a first operating position where the robot is separated from a mopping module, and a second operating position where the robot mounts a mopping module.
  • The transfer module is configured to transfer the mopping module between the storage module and the operating position, and can cause the mopping module to at least partially move in a vertical direction.
  • The system includes a mopping module collection unit and a mopping module providing unit, which work together to transfer the mopping module between the storage module and the operating position.
  • The patent includes 16 claims that outline the key features and functionality of the robot cleaning system.
