Don't do it!! Steam cleaners are almost impossible to have repaired and they don't last very long. We have never heard of it and we are in the industry.
Renting a carpet cleaner once a year called the CP3 by Thermax would be a better bet. For spilled or accidents just blot is up immediately with paper towels or white towels. Then use a mild soap solution to clean and rinse with plain old water using towels to absorb the stain. I have The Vacuum Shop in Round Rock if you would like more info. ###-###-####. M.
