Bought this machine from Costco. Thought it would be cheaper than my Hoover because I could mix my own solution for about 3 or 4 dollars. Now after getting the machine I find they don't sell the concentrate stuff anymore so I have to pay 10 bucks for a bottle of already mixed solution. Shame as I gave my nice Hoover carpet shampooer to good will. I think it was kind of a scam to make people think it would cost them only 3 bucks for a bottle to refill yourself. Then discontinue the self mix concentrate so people have no option to get the mix-it yourself concentrate. I have bought Shark vacuum cleaners .But feel I was kind of scammed with the Shark professionalism. So won't be buying or recommending Shark anymore.
Bottom Line: No, I would not recommend this to a friend
