Hi Curly. Just to say my OH has just brought himself a new toy a Robo Vac! OH takes get delight in setting it up and leaving to to clean the carpets downstairs and kitchen floor. It does a good job and with in half an hour even picks up my two cats white fluff. It also came with a charger. The cost was just over £50 and that included the postage I think. Not nearly as expensive as those shown on a TV program I saw just the other day but as you may have guessed it won't be able to do the stairs!
