I've used the part mainly to the car eyes. The quality is good, the unit despite robust plastic. There is a large vacuum cleaner filter bag, so you can dry (ie normal) suck. When one sucks Wet or water must Rauss the filter bag. On Ausblaseteil / engine part above is still a paper filter (such as an air filter in a car), this filter is always there. The suction power is good. I fully satisfactory for the money.
