A Dyson DC07 Allergy, (Preferably in green and purple.) and an All Floors (Preferably NOT faded.), A DC11 allergy (Come on, they're in mint and purple, what's not to like?) and probably any earlier Dyson machine.
What are your earliest and favorite vacuum memories?
We all owned a toy Henry, come on?
What is the history of vacuum you have owned?
I had an alright collection, mostly made up of Dysons, but I sold it because I wanted to put the money elsewhere. It had a DC07 CLIC, most notably. (Yes, I do regret selling it.)
Have you ever worked on, repaired and/or restored any vacuum cleaners?
Apart from the average filter clean, wipedown and part replacement, no.
