In a world where this 'simplicity' fad is in full swing, this type of maintenance is ridiculous. Too many parts to clean way too often. And with the technical abilities of the average user, this cleaning is not going to be done and the unit will be in the trash in no time.
Heck, even if a mechanical whiz services it after every use, the plastic clip that holds the whole thing together will break or the critical seal will get cut and it will be in the trash in no time since those parts will not be available.
Built-in obsolescence at its finest...
Makes me love my old Kirbys. I can neglect them for 25 years and they never fail me. One bag a year and a belt every 2 or 3 years. Almost every part is available if needed, despite there being no easy-to-break parts on most models. Very low maintenance machines.
