Not effective

Don't waste your money on this. It is completely ineffective. The brush head does not even contact the surface you are trying to clean. The rubber finger part of the brush can be removed to get the bristles of the brush closer to the surface you are trying to clean. However, the brush slows to a complete stop when it contacts a surface. The brush was being powered by a shop vac so lack of suction was not to blame. The impeller design allows for too much airflow around it.
