I can't see Alex's comments, but I do the same as your mother, Benny. The upright is my go to for vacuuming the open areas throughout the week and then the cylinder is my deep cleaner for getting in the tight corners of the room and, of course, above floor. Sofa, curtains, stairs etc, as well as dusting down surfaces like windowsills and book cases.
And re: the backwards comment, frankly I'm not taking advice from anyone who can't grasp the idea that vacuuming is not just about carpets and doesn't vacuum their sofa. I'll stick to my system, it's working well for me.
