A floor treatment device including a housing, a brush motor and a rotatable roller disposed in the housing. A suction mouth is disposed in a portion of the housing. The rotatable roller is driven by the brush motor and at least partially extends from the suction mouth. The rotatable roller is resiliently mounted in the housing such that the distance between an axis of rotation of the rotatable roller and the housing portion is variable.

A suction nozzle for a vacuum cleaner that can be connected to a suction pipe and/or a suction tube of the vacuum cleaner includes a nozzle part that can be connected to the suction pipe or the suction tube by means of a tubular connection part. A dust sensor is arranged in the flow path of the vacuum cleaner, the signals thereof being evaluated by a battery-operated electronic control device that can be activated by a low-pressure switch. During operation, said control device controls a display device displaying the dust flow. The control device, the low-pressure switch, the display elements displaying the dust flow, and a battery compartment for receiving the batteries are arranged in a housing formed on the upper side of the tubular connection part. The dust sensor is arranged beneath the housing, inside the upper region of the connection part, in the dust air stream.
