Abstract
A vacuum cleaner nozzle (N) comprising a rotatable brush (B) having a light distribution mechanism for distributing light from the rotatable brush (B), a transparent screen (S) through which a user can see the rotatable brush (B), and a drive unit for rotating the rotatable brush (B). The light distribution mechanism may have a plurality of lighting positions (L) on the rotatable brush (B). The light distribution mechanism may have a plurality of light sources distributed over a surface of the rotatable brush (B). The light distribution mechanism may have a light guide (LG) inside the rotatable brush (B), from which light escapes at the plurality of lighting positions (L), and may further have a light source (LED) for applying light to the light guide (LG). Alternatively, the light distribution mechanism has a plurality of mirrors at the lighting positions (L). The vacuum cleaner nozzle (N) may further have a sensor for measuring a rotation speed of the rotatable brush (B), and a controller for controlling the light distributed from the rotatable brush (B) in dependence on the rotation speed. The vacuum cleaner nozzle (N) can be applied in a vacuum cleaner further having a dirt collecting unit for collecting dirt.
