I had a plant when I was in California and may end up sorting one out over here. So I was surprised that the comment is that they are very expensive. I am not questioning it at all as I dont know just surprised. We usually cleaned the area rugs for about 1/4 of the price that the techs would then charge their customer. This way the rugs were cleaned properly and the techs had it easy as they had more time to do anything else. Lavinia, may I ask how you clean the rugs. There are rare occasions and rare people I know but on the whole you will get a much better result from those who are cleaning them all day long and have all the right "stuff" to clean them with. I have rugs sent to me to be cleaned because of the way I clean them as I am sure a lot of company's do. That way we are all happy, I get mine so to speak and the tech gets his.... At the end of the day it is money for almost nothing so the profit to the tech is way higher than anything else he is cleaning. Best, Dave.
