Got this to vacuum the car out (the machine at the local service station always seems to be out of order). I have 1.5Ah batteries from the drill and I vacuumed the front and rear seats and floor along with the boot. The battery still seemed to have plenty of go in it. The machine is quite loud, but seemed to do the job well. It is a bit fiddly getting the bin off to empty it the first time, but that should be easier the next time.
