I agree. I maintained a dyson (I think it was a V6) for a couple of years. They are generally designed so well, it literally pokes your eye where they made the materials extra thin to break earlier (for example the pipe connection mechanism and the electrical connectors)
I gave up when the main body started to break. Using a Philips now. Better in many ways but still far from perfect.
The availability of spare parts is really good though for dysons. Lot of cheap stuff on Amazon and eBay. Buying a spare battery for the Philips for example is much harder.
This is the correct answer. Don’t overthink this. Just go, have a look and that’s it. Tell everybody involved that you don’t have to proof anything if they ask.
I know people who could afford this house easily that walk around like a regular farmer. Sales people having regular contact with wealthy people know this.
