Anyone else had this problem and if so how did you resolve it. When vacuuming I notice there are lines of dust/dirt deposited on the carpet behind the brush head, usually when changing direction. From memory this has been the case since day one and despite trying all the usual things like cleaning filters and checking for blockages I can’t stop it. Have a look at the attached pics and if you recognise the problem and have a solution please let me know.
Thanks
