I used mine tuesday. Iv;e had it over 15 years it sits in the garage, but it saved the carpets. The job was a section 8 eviction not to common.The house was gased 6 times and the roaches were still everywhere. The carpet was a berber. I first cleaned with a push broom. then used a shop vac then the upright to finish. I pre sprayed with cobbs prespray and added his powdered grease cleaner mixed both and then used the
RX20 and I had to empty my filter every 15 min. The end results were GREAT, now I hope that they don't have children crawling on the carpets, but the results were better than expected because of the
RX20.
