Bissell 2X Proheat 9200 - uses lots of cleaner.

Question

I bought a Bissell 2X Proheat 9200 rug cleaner. Seems to do a good job, but goes through the cleaning solution and water very quickly. I followed directions on amount to apply. I went through almost a whole bottle to clean on rug. The clean setting was on heavy duty, but stil shouldn't have used that much solution.
