Publication number: 20230037747Abstract: 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.Type: ApplicationFiled: December 23, 2019Publication date: February 9, 2023Applicant: Aktiebolaget ElectroluxInventors: Petter Forsberg, Magnus Wennerström, Magnus Lindhé, Fredrik Kange

Publication number: 20220287522Abstract: 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.Type: ApplicationFiled: September 4, 2019Publication date: September 15, 2022Applicant: Aktiebolaget ElectroluxInventors: Jens Leffler, Magnus Wennerström, Andreas Klintemyr

Patent number: 11122953Abstract: 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.Type: GrantFiled: May 11, 2016Date of Patent: September 21, 2021Assignee: AKTIEBOLAGET ELECTROLUXInventors: Johann Zita, Magnus Wennerström

Publication number: 20160302637Abstract: 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.Type: ApplicationFiled: December 20, 2013Publication date: October 20, 2016Applicant: Aktiebolaget ElectroluxInventor: Magnus Wennerström

Patent number: 8943644Abstract: 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.Type: GrantFiled: November 5, 2009Date of Patent: February 3, 2015Assignee: AB ElectroluxInventors: Tommy Andersson, Magnus Wennerström, Henrik Nygren, Gunnar Lundmark

Publication number: 20110308037Abstract: 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.Type: ApplicationFiled: November 5, 2009Publication date: December 22, 2011Inventors: Tommy Andersson, Magnus Wennerström, Henrik Nygren, Gunnar Lundmark
