I’ve been repairing my 2 dyson vacuums for the past 8 years at Glenview Vacuum (before that had my Hoover repaired). My dysons would last for 1 1/2 - 2 years or so and then I’d notice crumbs and dog hair that wasn’t picked up. After they serviced them they picked up much better. About 3 years ago I bought a great new Riccar upright from them which uses bags and it works better than either of my dysons ever did
