This is even more important with pet accidents. The last thing you want to do if your dog or cat has had an accident on your carpet is to spray it and let it be. It might mask the odor for a bit but the "mess" is still in your carpet. Again, what if a toddler had an accident in his pants? You would never think of simply spraying the pants and then allowing them to be worn again! This is why it is so important to call a professional carpet cleaner who has the equipment to flush and extract the accident from your carpet.
But how do you know if the person you're calling has the right equipment to do this? It takes a powerful machine to extract everything out of the carpet fibers. One of the most important questions you should be asking is whether or not the carpet cleaner has a truck mounted machine, or a portable cleaner. A truck mount is heavy duty and is permanently mounted in a truck or van. A portable unit is light weight and, well, portable. A truck mount runs on gas, a portable off of your homes electricity. It would be the difference between using a gas powered Toro snow blower vs a Black and Decker with an electric cord. If you want your driveway cleared, you'd choose the Toro! And if you want your carpets clean choose someone (like Pristine Floor Care) who operates a truck mounted carpet cleaning machine.
