No matter what and how much is drawn each time the complete vacuum cleaner must be opened and emptied. Where the exact problem is, could not yet be determined. We had opted for a new vacuum cleaner, after our old Dirt Devil has burst on the attachment. Since essays and pipes are very expensive to replace, we bought a new equal sucking (10 EUR more) - now we use our old vacuum cleaner and pipe and tower of the new, as this is not always empty. That the tube continuously drops when vacuuming simply without warning (and a sometimes beautifully painful pops up on the toes), was both the ancient and the new vacuum cleaner is a problem, you have to keep everything firmly hold).
