The machines that you rent at the store are not as powerful as truck-mounted equipment. You are relying on 15-amp circuit to power the machine. The chemicals that you buy for the rental machines are not strong enough to get the job done. The manufacturers could not get product liability insurance to cover the product. Truck mounted machines are more powerful and efficient. They have higher water temperatures and stronger vacuum, leaving the carpets cleaner and dryer. By not getting the water out, you are not getting the dirt out, and you are leaving chemical in the carpet to attract soil.
