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.

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.

Brush for a vacuum cleaner

The present disclosure relates to a vacuum cleaner comprising an electric motorand a blower producing an air flow through the vacuum cleaner. The electric motor and the blower are placed on a common vertical axis. A separator unitis placed laterally with respect to the common axis of the motor and the blower. A bent conduitconnects the blower with the separator unit, and one endof the conduit encloses the common vertical axis. The conduit comprises a portion located along the common axishaving a double wall forming a closed air pocket. This provides damping of noise emitted by the blower/motor and which propagates in the opposite direction of the air flow.
