“Expense but very useful”
I really like using this machine for shampooing my carpet. The only draw back is that the silver tank does not allow me to see the water level. I have had a similar machine before with a white tank and I could see how much cleaning fluid and water was in the tank. I had been looking for this type of machine for several years and was unable to find one thinking that it was discontinued, but when I ran across this one from Sears, I jumped on it to buy. I love the machine but not the price.
