I am pleased with this woven rag rug.  It is bluer than I expected but I like it.  It does have knots that can be felt when barefoot but I don't think that they are a problem in the location in which I have it.  I really like the different shades of blue and beige and like the fact that it is handwoven.  I have not had it long so have not vacuumed it yet, but I don't anticipate a problem.
