First of all I would like to say that this vacuum cleaner is only suitable for light dust. This piece has 2 levels of suction. And to be honest I don't see or feel any difference. Nozzles for penetrating small cracks. GARBAGE. With horribly low suction, this nozzle makes matters worse. The only good thing about this product is the small brush that comes with it. It's really the only useful thing I use for removing small bottlenecks, like between keys on a keyboard. Overall I give 2 stars.
