I've been using this unit for about 7 years now. First bought for cleaning after repairs. I liked the absence of all sorts of filters, unnecessary components and assemblies. For a couple of years he still lived in an apartment, after which he moved to a garage (heated box). Removes all dust, dirt (both already dried and wet - after snow and rain). I have never changed the rubber brush yet. The absence of filters makes it absolutely unpretentious to the particles being removed - dust, sawdust, metal dust, small debris that can crawl into the pipe, small stones, sand, pieces of plaster . in general, everything that needs to be removed in the process of repair or economic activity. As soon as a drop in suction power is noticed, the collection bag is completely clogged. Changes to a new one and goes back to battle. The wire is long enough. For all the time of operation no complaints. The only thing I can write down as a minus is the price tag for replacement bags. But I took them all the time once in a set - enough for a long time.
