Not when we clean it.
There’s a reason people believe this, though–it has to do with a shortcut that many carpet cleaners use. They run detergent through the wand, so the last thing that hits your carpet is soapy water. Soap’s job is to attract dirt, so your carpet starts collecting dirt faster than ever. Talk about a waste of money!
How we are different
We put down a cleaning solution in our first step and give it a little time to dwell. Then, after brushing it, we extract with clear water, so that’s the last thing to hit your carpet. The cleaning solution is extracted along with the dirt from your carpet.
