I had the most powerful Dyson one and it stopped working in under three years. (I do have two fluffy dogs, cats, and boys, though.) After about just 18 months I had to repeatedly stop vacuuming to remove clogs. It was super annoying. I'm planning on buying either a Shark or a cheap amazon one next. IME the price of the Dyson isn't worth it.

I am thinking now
of grief, and of getting past it;
I feel my boots
trying to leave the ground,
I feel my heart
pumping hard. I want
to think again of dangerous and noble things.
I want to be light and frolicsome.
I want to be improbable beautiful and afraid of nothing,
as though I had wings.
