What a fascinating discussion. I completely agree about using Festool CTs with the Tradesperson/Installer Cleaning Set cat 497 700 especially with the addition of the Plastic Turbo Suction Brush cat 450 644.
Just after Christmas 2005 my previous home vac died. A block from my condo there was a shop specializing in home vacs, repairing and selling them. The owner, who I trusted, told me I needed a new one. He had several brands. I selected a Miele, because a friend owned one of their dishwashers. It was expensive and performed better than any vac I had owned before.
Then on the 3rd Friday of 2006 I started a 4 week vacation, planning to build two cabinet-related projects I had been designing all of 2005. My plan was to lease a shop. A trusted pal had sold me a lot of high-end woodworking equipment for my previous shop, so I drove to his new store, intending to buy a large slider-table saw. He talked to me about my plans for the shop. I explained I had two spare rooms in my condo and that I hoped to delay retirement as a movie studio executive until late 2007 but I was willing to least a shop as soon as my Realtor could find one. Before showing me slider saws, he told me that many of his clients were using Festool track saws instead of sliders to break down plywood sheets. The advantage was not just moving the saw instead of the sheet, but also the dust extraction. He had me try a TS55 with a CT22. I loved that idea and those tools. I immediately took the saw, CT22 and 3 rails home.
The next day was one of the Saturdays when he held open house at his store. A whole gaggle of top woodworkers gathered there. One told me that I would collect more dust from my TS55 if I used a 36mm AS hose, and the best way to buy that was to by the Tradesperson set, which included the 36mm x 3.5m AS hose. Another woodworker told me that he used the Turbo brush to clean his home carpets. I was happy with my Miele for cleaning my carpets, but I figured the CT would live in the leased shop so I should have the Turbo brush.
Finding a shop to lease was not as easy as I thought, so I had several sheets of plywood delivered to my condo. I used the TS55, the rails and the CT22 to break down the sheets and was pleased with the dust collection from the 36mm hose. But drilling holes and so on created some saw dust. I used the Miele to clean up that. Then before I finished the two projects my studio asked me to return to work a week early. The TS55 and CT22 were quiet enough I could use them after work in my condo, but the Miele made enough noise I could not use it either before or after work.
I knew I did not need to turn the suction up all the way with the 36mm hose with the saw. So I tried using the Turbo brush with the suction reduced. It was so quiet I could not hear it in the next room. It had more than enough power to remove the saw dust from my carpet. None of my neighbors noticed that sometimes I was cleaning my condo at 4 A.M. using the CT22 turned to minimum.
All these years later my Miele is still virtually brand new. I kept buying more CT22 and a couple of other Tradesperson kits because instead of leasing a shop I rented space in shops of pals, sometimes two shops at the same time. I keep a CT22 with the kit and Turbo brush at home, although since I retired in early 2007 I do not clean the place in the middle of the night.
