  • Robotic cleaner having acoustic surface type sensor
    Patent number: 11937766
    Abstract: A robotic cleaner may include a main body, one or more drive wheels coupled to the main body, one or more surface type sensors coupled to the main body, the one or more surface type sensors being configured to receive robotic motor sound reflected from a surface to be cleaned, the robotic motor sound being generated by one or more motors of the robotic cleaner, and a controller configured to determine a surface type based, at least in part, on the reflected robotic motor sound.
    Type: Grant

  • ROBOTIC CLEANER
    Publication number: 20200383547
    Abstract: A robotic cleaner for autonomously cleaning a cleaning surface. The cleaner may include an agitation module configured to directly agitate a forward edge of cleaning pad. According to another aspect the cleaning pad may have a rigid strip at a leading edge thereof for slidably engaging a channel in a wet cleaning module to removably couple the cleaning pad to the wet cleaning module. According to another aspect, the cleaner may include wheels having a gapless tread configuration.
