It's Perfect

The Perfect Heat system on certain Powr-Flite portable carpet extractors is designed to provide consistent heat at the wand tip throughout the carpet cleaning process. In “real world” tests comparing the Perfect Heat system to competitors, temperatures at the wand tip were not only higher but they were consistently higher, the company said.

This means better performance because heat improves the effectiveness of cleaning chemicals. In addition, less chemical may be needed, making the carpet cleaning process greener as well.
