Thanks both for the input. Instead I spoke directly to Dyson via their live chat and would you believe it they have offered for me to get a brand new Dyson for free. The two he said he could exchange it for are the Dyson v7 cordless which to be honest is not much air watts in them but still good, or the Dyson big ball total clean cylinder. My mum choose the cylinder one as it comes with all the tools and it's brand new with 5 years guarantee.
They are coming to pick up / deliver it on Tuesday this week.
Thanks both though.
