I read lots of mixed reviews on this steamer, but decided to purchase and take a chance.  It worked great for about 9 months, then the steam quit coming out.  I did not use tap water and tried cleaning with vinegar, thinking that sediment had built up inside....no luck.  This cleaner was too expensive to last less than a year!

Pros: Worked great for awhile.  Cleans grout, but brush wears out quickly.
Cons: Quits working within a year and extra pads are expensive.
