My mate Kev this week using a copper disc with his. I had a go and was down the other end of the room in seconds.
There are loads of Nilfisk models about though. I have four, some of which work, some are for spares. Some 240v some 110v. The 701 is the best model, even if it`s a bit of a pain being 32 amp. Spe carry all the spares, and accessories, with next day delivery.
The Str machines are bang on, heavy enough and can be a pain carrying up stairs though when the lift is out of order!
Stg450 machines great buffers but pack a kick, not as much kick as when you get the invoice for them though
Does any one know if the victor 450 with dust extractor would be any good or is it 2 high speed cheers
