There are steamers without an extraction process and steamers with them. The ones with them cost much more. It seems to me that you would need the extraction version for a tightly woven carpet - but I could be wrong. I was in a store the other day that had the pebbles in resin and thought it looked pretty cool. I wondered whether my steam cleaner (non-extraction) would clean it in the same way that it cleans my ceramic tile. The cloth cover might catch on the pebbles. But the extraction method probably doesn't need the cloth cover. You might want to call some of the companies that sell the machines and get their advice on your particular application. I bought my machine from Vapor Clean and they are pretty good about telephone consults. Here is a link that might be useful: Vapor Clean

I have the H3060, the very first one on the page I linked to above. Don't be shocked by the price though; I bought mine brand new for about $75 less than what Hoover advertises it for. I like it a lot. It comes with two brush block assemblies, one specifically for cleaning grout. Hoover also sells a special grout solution too. It works very well, and never "reuses" water, so you're always putting down fresh water and dirt is never spread around. I guess the only gripe I might have (and even then I understand the design decision by Hoover perfectly) is that it scrubs very lightly. With brushes spinning at a very high speed there is a balancing act of pushing too hard (which could damage wood or linoleum) or pushing just hard enough to clean tough spots. Hoover erred on the side of caution, so any ground in dirt, scuff marks, etc. still require a pre-scrub by hand to loosen them up. Otherwise, no complaints. Spills, normal dirt, etc. are all picked up very well and the floor left sparkling.

Hi, we are currently trying CLR, but not fixed yet. I think hubby will have to take the machine apart & see if there is a blockage. Thanks for the suggestion of vinegar though.

Have never heard of that brand, but reading the specs, it looks great. Made in the USA, stainless steel boiler, high steam pressure. Even the smallest one is powerful. Make sure you get the optional wheels. Also check to see how the gun operates - make sure you don't have to keep pressing the button to keep the steam flowing. What are you planning to do with it?
