The filter bag is attached to the connector plate and the sleeve is provided outside the filter bag. The sleeve is arranged to keep the filter bag in an initial folded position and allow the filter bag to expand when air is blown through a hole formed in the hole section of the connector plate.

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.

Abstract: The invention relates to a crisper for preservation of food. The crisper (10) comprises a box (12) and a top (14)—When the crisper (10) is in a closed position the box (12) is air tight sealed to the top (14). A humidity control unit (16) is provided and adapted to allow humid air to exit the crisper via a 5 humidity control membrane (26) located in the humidity control unit (16).

Abstract: A robotic cleaning device configured to detect objects as the robotic cleaning device moves over a surface to be cleaned. The robotic cleaning device has a first light source configured to produce a close range wide light beam in front of the robotic cleaning device, a second light source configured to produce a long range vertically-narrow light beam in front of the robotic cleaning device, and an array sensor configured to detect light reflected from one or more of the light sources to detect illuminated objects from which said light is reflected.

Abstract: A robotic vacuum cleaner having a nozzle arranged in a portion of a housing facing a surface to be cleaned. The nozzle has a leading edge portion having channels leading to the suction opening at two different heights from the surface.

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.
