A couple of risks in any of these cleaning methods are Browning and Returned Stains. They are generally easy to handle.
In Marin County, the majority of the carpet cleaners fall into the Conservative, Economy, and Dry Cleaning methods. Several fall into the Intensive or High Quality category. For the most part, the Intensive Cleaners are going to charge more for their services, for good reason. We, at Atlas, consider ourselves Intensive Cleaners.
One of the major items that separate us from the other intensive cleaners is our tools (for rinsing and extracting). They have incredible rinsing power. As it rinses, it also agitates. They have the ability to move real slow or even stay still without over wetting or soaking the carpet. While that is happening, the heat levels are getting increasingly high within a steam chamber. Basically these tools outperform everything else that’s out there in soil removal.
As we have always said, any kind of cleaning method (even a rental) should improve the look of your carpet, though is it the best cleaning?
Hopefully, we have helped educate you that all carpet cleaners, methods, and systems are not equal.
