  • Publication number: 20230037747
    Abstract: A method of controlling movement of a robotic cleaning device and a robotic cleaning device performing the method. The method comprises acquiring historical data forming a representation of an environment in which the robotic cleaning device moves, and controlling movement of the robotic cleaning device to exert a force onto an object located in the environment to move the object based on the acquired historical data.

  • Publication number: 20220287522
    Abstract: An autonomous cleaning robot having a body, a driving means configured to move the robot in a forward direction over a surface being cleaned, a suction opening arranged at an underside of the body, and a roller arranged at the underside of the body and in front of the suction opening, relative the forward direction. The roller is configured to define a front air passageway at the surface, and comprises bristles arranged to form a front air barrier restricting an air flow in the front air passageway. The front air barrier is configured to be substantially uniform over an entire turn of the roller, wherein the bristles are further arranged to direct the air flow towards a particle passing by the roller, and further into the suction opening.

  • Patent number: 11122953
    Abstract: A robotic cleaning device having a main body, at least one drive wheel, at least one linking member rotationally coupled to the main body about a suspension axis and rotationally supporting the at least one drive wheel about a drive wheel axis such that at least a section of the main body can be raised from a lowered position, closer to the ground surface, to a raised position, further away from the ground surface. First and second spring members are arranged to provide a moment on the linking member about the suspension axis in the first direction to press the at least one drive wheel towards the ground surface. The moment provided by the first spring member is higher in the lowered position than in the raised position and the moment provided by the second spring member is higher in the raised position than in the lowered position.

  • Patent number: 10231591
    Abstract: A dust container for an autonomous cleaner. The dust container includes: a container wall enclosing a dust chamber; a first side; a second side; an inlet opening to the dust chamber for dust particles and air arranged in the first side of the container; an outlet opening from the dust chamber for air arranged in the second side of the dust container; and a filter arranged in the dust container such that the flow of air through the dust container pass through the filter. Also provided is an autonomous cleaner having the dust container.

  • Publication number: 20160302637
    Abstract: An autonomous cleaner having: a cleaner body in which a cavity is defined; and a dust container removably fitted in the cavity, the dust container having an air and debris inlet, and an air outlet for admitting an air flow through the dust container. The dust container has a dust compartment for the debris, and the ratio between the dust compartment volume and the cleaner body volume is within the range 0.1 to 0.2.

  • Patent number: 8943644
    Abstract: The present disclosure relates to a vacuum cleaner comprising an electric motor 3 and a blower producing an air flow through the vacuum cleaner. The electric motor and the blower are placed on a common vertical axis 17. A separator unit 13 is placed laterally with respect to the common axis of the motor and the blower. A bent conduit 19 connects the blower with the separator unit, and one end 21 of the conduit encloses the common vertical axis. The conduit comprises a portion located along the common axis 17 having a double wall forming a closed air pocket 23. This provides damping of noise emitted by the blower/motor and which propagates in the opposite direction of the air flow.

  • Publication number: 20110308037
    Abstract: The present disclosure relates to a vacuum cleaner comprising an electric motor (3) and a blower (5), producing an air flow (9) through the vacuum cleaner. The electric motor and the blower are placed on a common vertical axis (17). A separator unit (13) is placed lateral with respect to the common axis of the motor and the blower. A bent conduit (19) connects the blower with the separator unit, and one end (21) of the conduit encloses the common vertical axis. In the prolongation of the common axis the conduit comprises a portion with a double wall forming a closed air pocket (23). This provides damping of noise emitted by the blower/motor and which propagates in the opposite direction of the air flow.
