Tried my neeeewwwww Challenger last night on a bank owned home that I bought. The WORST thick filtration lines and d-i-r-t-y/s-t-a-i-n-e-d carpet. Bought Cyclone from Vacaway. WOW! BINGO! Baseboard and vent lines for the most part are gone (saving $2k on new carpet). Orbit and Spot & Boost cleaned carpet well. Great machine and great products! This is going to be fun. Thanks Mark and Brooks for getting the package out to me on time. I can starting moving the furnniture in TODAY! My wife was VERY pleased with the carpets! I had my 9 year old son work the machine a little. It is a simple to operate piece of money making equipment. Best regards, J.R.
