  • Publication number: 20240033781
    Abstract: A cleaning station for a mobile robot includes a fluid vessel and a roller arranged in the fluid vessel. The fluid vessel is shaped to hold a cleaning fluid that at least partially submerges the roller. The cleaning station includes a control system configured to, when the mobile robot is docked at the cleaning station, cause rotation of the roller to direct cleaning fluid from the fluid vessel to a cleaning pad of the mobile robot in order to release debris from the cleaning pad.

  • Patent number: 11871888
    Abstract: A cleaning roller mountable to a cleaning robot is featured. The cleaning roller includes an elongate member extending along a longitudinal axis of the cleaning roller, and a vane extending outward from the elongate member. The vane includes a first vane portion attached to the elongate member, and a second vane portion attached to the first vane portion. The first vane portion extends from the elongate member at a location intersecting a radial axis of the cleaning roller. The first vane portion extends along a first axis angled relative to the radial axis and away from the radial axis in a tangential direction. The second vane portion extends along a second axis angled relative to the first axis. A first angle between the first axis and the radial axis is greater than a second angle between the second axis and the radial axis.

  • Patent number: 11641991
    Abstract: A cleaning bin mountable to an autonomous cleaning robot operable to receive debris from a floor surface includes a debris compartment to receive a first portion of debris separated from the airflow and a particulate compartment to receive a second portion of debris separated from the airflow. The cleaning bin also includes a debris separation cone having an inner conduit defining an upper opening and lower opening. The upper opening receives the airflow from the air channel. The inner conduit tapers from the upper opening to the lower opening such that the airflow forms a cyclone within the inner conduit.
