I don't know it it is the same over the pond but here in the UK once you have bought a Dyson you never have to buy another one, unless you want to change your model because every single part of a Dyson is replaceable, available online and easy to install.

My present one is nigh on 16 years old and has 2 replacements, filters which cost a tenner or so! Go Dyston go
