Oh and I tried out the Anko carpet shampooer. It’s not bad, I will warn you that it drinks up carpet shampoo fast as the small tank of solution doesn’t go very far.
Just to clean a short diagonal path where it was grubbiest and a few small areas next to it took two fills of the clean solution tank and two empties of the dirty tank. I used half the smallest recommended amount of cleaner on the second tank because that stuff is not cheap.
You can definitely get away with a smaller amount of cleaner and you may want to buy a bigger machine (Anko or not) if you want to do a whole area without constantly stopping to change the tank a bunch of times. I got the little one for price and storage considerations but it’s probably easier as a spot cleaner for small sections.
Don’t set the clean tank on its side while finding the shampoo bottle as it can leak (soaking your carpet).
It’s also extremely loud. Screamingly loud. My ears were ringing.
But it pulled out a lot of dirt into the water and the spots I did look cleaner. Dried okay as far as I can tell.
