I know this has been done before and I have looked at the old threads but what would you recommend for a house that mainly has wooden floors. We have a Dyson that just keeps conking out, it's driving me mad. It's so heavy and cumbersome we've decided to ditch it and get something else. A friend has recommended Miele - the prices vary so much. It is worth getting the super duper powerful model at around £250? What do you lot think? Thanks for your help.
