Have used RCL for a office carpet cleaning. They did an amazing job despite our carpets were so filthy that we never thought that they will be refreshed in such amazing way. Even ink around our printers somehow disappeared. Office now smells better and traffic areas look much cleaner. I recommend to everyone to book a professional carpet cleaner at least once a year if you want to have brighter look and appearance on your carpet. We got also 2 sofas cleaned and few chairs done, same result quality job. We were very impressed with RCL.
