wifey is a bit of a dyson hoover nut/fan, whatever you want to call it..... lol
anyhow she bought the hand held recharable dyson hoover....and i think its brill ,seems to do both cars no trouble on 1 charge, and ive fixed it to the wall in the conservatory ,so it can be used for odd jobs around the house aswell.........nothing stopping you from leaveing it in the car though.
it does not come with a 12v car adaptor though,weather 1 can be bought for it?

??
but unlike other rechargeable stuff i have it seems to hold the charge it has very well !!!!!
pat.
