Unfortunately Earlex stopped making vacuums. I have their wet and dry which has been going strong for about 10 years now. When it breaks I'll be looking to replace it with something that takes bags, probably a Numatic Charles.
I have a wickes one or tesco not quite sure but I had it for the wood saw so it will grab the worst of the chippings when its turned on.Can't remember what make mine is, but it does have a handy socket to plug power tools into so when I switch on the planer for example the vacuum starts automatically and runs for a few seconds after switch off
