We have been using Advanced Cleaning Systems for our workplace for about two years now and they have consistently delivered very good service. Their technicians are very knowledgeable and thorough. They are polite and friendly and they represent their company well. They know their business and they give you the real scoop about your carpet. When they have done the job, they will the leave you a little container of cleaner for spots in case you need it. I believe they are a family owned business that has been around for a long time. They know what they're doing. They come when they say they will and they do do what they say. They also work around what you really want. For example, there is some furniture here that we don't want moved and they're very careful about that sort of thing.
