Those rugs on Etsy could be falsely labeled as hand woven, or are very used. Used rugs don't sell for nearly as much as new. Think about trying to sell a couch or bed mattress used. As for cleaning, my business recommends a thorough cleaning every 2 to 4 years depending on use. You can use a mild detergent and a hose to clean yourself, but that can have a ton of issues mine color bleed or warping. But they are tough enough to take a light power washer without damage. Do a dye test first. Put a wet paper towel on different areas of the rug and see if any color transfers to the towel. If the dyes bleed when wet, get it professionally done by a place accredited by ARCS. I can tell you from experience that those colored threads wrapped around the end tassels will bleed and leave you with red, blue, and green tassels and instead of white cotton. And it's really hard to reverse without damaging the cotton.
