Answer 1

*The Vortex Is The World's Most Powerful Cleaning Machine. The Vortex is an inventor's dream of a better cleaning machine come true. The Vortex is the only mass produced mobile cleaning machine in the world capable of safely capturing wasted energy from its own engine exhaust to heat water. Additionally, the machine's high-torque, high-efficiency power plant allows three operators to clean from one machine simultaneously, while decreasing fuel consumption by over 40% and improving textile dry times by over 47%.

*The Vortex is famous for its ability to clean carpets faster, use less fuel, clean more thoroughly and require less operator muscle than any other cleaning machine in the world. Even with three operators cleaning simultaneously, the Vortex will provide more vacuum and hot water than any other PTO cleaning machine can produce running only one wand! There is so much vacuum on our Vortex that our clients are reporting dry times of less than 90 minutes without the use of a carpet fan.
