Carpet shampooer

Finally found where the 'movers' had stashed the rolled-up carpet at the new place. Before we sling it in the master bedroom, it could do with a good, deep cleaning. Has anyone seen a carpet cleaner/shampooer in Udon? I saw some decent wet & dry power vacuums in a couple of shops but haven't seen any proper carpet cleaning solutions. I have seen aerosols of 3M carpet cleaner but that method would be very expensive as it's mainly for spots.
