Abstract: A side brush for a robotic vacuum cleaner includes a brush core, a plurality of bristle clusters having a first length, and a plurality of further bristle clusters having a shorter length than the first length. The plurality of bristle clusters and the plurality of further bristle clusters are regularly distributed over a circumferential surface of the brush core.

Abstract: A robotic vacuum cleaner for autonomously cleaning surfaces. The robotic vacuum cleaner comprises an appliance housing and a side arm. The side arm is movably mounted on the appliance housing. A brush element is disposed on the side arm. The side arm projects, in a first position, in front of the appliance housing in part and, in a second position, is received by the appliance housing. The side arm comprising a first arm element having a first end and a second end. The first arm element is movably mounted in the appliance housing at the first end. The side arm comprises a second arm element having a first end and a second end. The second arm element is movably mounted in the appliance housing at the first end and is movably connected to the second end of the first arm element at the second end.

Abstract: A robotic vacuum cleaner includes a movable side arm. The side arm is inwardly pivotable into the inside of a housing of the robotic vacuum cleaner by a spring mechanism in the event of contact with an obstacle. The side arm is mounted on a rotary shaft so as to be pivotable and linearly displaceable along an elongate hole.

Abstract: A robot vacuum cleaner includes a housing and a brush roller disposed at a bottom of the housing. The brush roller is configured to be rotatable about a horizontal axle. A blade is disposed above the brush roller in stationary relation with respect to the housing. The horizontal axle is adjustable in height relative to the housing. The brush roller is spaced away from the blade in a lower position and is in engagement with the blade in an upper position.

Abstract: A rail vehicle includes a roof and a first shading plate disposed at a distance from the roof. The first shading plate has first openings for the passage of air.

Abstract: A vacuum cleaner includes a dust collection chamber, a cover configured to close the dust collection chamber and a mount for a dust bag disposed in the dust collection chamber. The mount is pivotable about a pivot axis from a first position blocking a closure path of the cover to a second position in which the mount does not block closure path of the cover. The mount is pivotable into the second position upon receiving of the dust bag. The location of the mount in the first and second positions and a position of the center of gravity of the mount relative to the pivot axis are configured so as to automatically pivot the mount from the second position to the first position when the dust bag is removed from the mount and when the vacuum cleaner is disposed in a normal operating position on a substantially level surface.
