SEBO – every time.
Looks plain, doesn't have a big motor or flashing lights. Just wonderfully designed and engineered. Made by Germans you see. The John Lewis salesman called it "The Mercedes of hoovers."
Easier/lighter to use than other hoovers. Works great on dog hair. Automatically adjusts brushes to correct height. You have to change bags/filters but it's easy enough.
5yr warranty and great back up service.
Got mine 13yrs ago. Still works like it was new.
My whole family bought them soon after(4 more) and still working fine.
They are just nicer and better to use than any other hoover I've tried. I'm sure Dysons work well enough but they're clunky, plasticky and awkward to use IMHO.
It's the BEST £200 I've ever spent on any ANY electrical item EVER 🙂
(And I've bought a LOT of stuff over my lifetime)
