dont think u can buy them now ? didnt world of cleantalk sell a newer version a couple of years back but thats gone too ? looks like there gone ...
having never used one i wouldnt know , but id imagine its a bit like using the old certified brush vacuum .... it works great on a small fraction of the carpets u clean , that arnt even popular anymore ... and slowly get hauled off the van less cause its a heavy bulky thing and something like the tm3 weighs a feather so il grab that insted ...
might be ok in your rug plant though if u can find one .
