We have had a DC35 for 18 months and are happy with it. Makes it very easy to vacuum, just grab it and go, no heavy awkward unit to lug about. Not a chore to get out, by the time i would have got our old one from under the stairs with the DC35 I’ve got it out, cleaned and put it away. We only have a small house and don’t have thick shag carpet. Just do rooms as and when they need doing, only an issue if you wanted to do a lot at once the battery may not last.
MIL liked ours so much she bought one. Easy for old people to do the stairs and carry upstairs too.
Makes doing the car easy too!
