Used it for the 1st time today. Job was 2 bedroom rental, HEAVY soiled poly frezzie (sp?) . The tenant was there for 5 years and the carpet had never been cleaned , black traffic areas , several spots (drink spills , grease, black spots etc.)
Mixed GE at minimum dilution of 2 oz per gallon. Sprayed heavy , let dwell while I set up. Cleaned up beautifully! Was slow going at first, It took 3-4 slow wet passes to get it clean, I felt like I was working harder than I should, so I fired up the sebo and gave it a good quick scrub. After that 1 or 2 slow wet pass and it was clean as can be. I didn't have to use any spotters , every stain came right out. It was real cool seeing the contrast of the white streak next to the black uncleaned area after doing a pass. The owner was thrilled with the result, and complimented me on the pleasant smell.
This would have been a major pad burner with the OP, and I feel like I saved at least 15-20 minutes by using TM/GE instead. Took me a little over 1 hour from start to finish. OP still seems to be faster or as fast on the less dirty ones due to easer set up times.
