Sebo Airbelt D4

“Ouch, that's a costly regret.  I don't routinely suggest the D4 because it's a tank of a vacuum and much too big to wield unless the house is huge and there's a lot of open space.  If you bought it at a local dealer, perhaps you can complain about your issues and see if they can consider a trade in/exchange.  I don't see Sebo vacuums being sold 2nd hand very often in my local sale sites, but when I do it's usually a D4 with people mentioning it that it's "too much vacuum" for them. It would be hard to recover your expenses on the 2nd hand local market, you'd be lucky to sell it for half.   Some of what you describe might be just the issues people encounter when they first use canister vacs and some people never adjust to them and will always prefer uprights.  Your D4 shouldn't be falling over, you should keep it on it's wheels unless you are vacuuming something like the stairs.  When you vacuum, enter a room with the canister behind you istead of reverse vacuuming out of a space like normally done with an upright.  Your non dominant hand supports the hose and pulls the canister behind you, while letting the hose wrap  around your backside and holding the vacuum wand in your dominant hand.  Go slow and keep corners and furniture in mind when pulling on the canister.  It may be that you will never like a canister format.  ”
