The filter is a bit BIGGER than it should be, so when a vacuum cleaner is closed not all the parts join seamlessly. There's always a small gap somewhere inside, so when I open the vacuum cleaner I see A LOT of fine grained dust on the black intake filter. Some air goes AROUND the water filter because the lid cannot fully close due the the over sized filter!  I own the DS6.000 for over 2.5 years and in never happened before, when I used only genuine filters.  Don't waste 50zl on this fake crap, buy yourself a genuine one, don't make my mistake :(  Attachment: intake filter after 5-10 minutes of using a vaccum cleaner. You can ALREADY see some dust, after only 5-10 minutes!
