Yes, I know: I'd never heard of them until I started investigating cleaners. Sebo, Bosch and Miele came out top in the Which and other reviews. Bosch uprights were hard to find; Miele was about £60 more than the Sebo and only had a 5 instead of 10 year guarantee.
So Sebo it is.
And so far so Sebo. (That doesn't really work, does it, as play on words of any sort?)
We've gone back to a bagged cleaner - the bagless was useless with a George in the house - but this time I'll read the instructions before breaking it. I mean instead of breaking it.
