I'm happy I made this purchase. I made a few modifications and I have one suggestion and one gripe.For the most part this unit is a real workhorse and very welcome in my shop or, as pictured here, on a project site. The vacuum is strong and the exhaust air is clean. The filtration system holds on to the fine particles and air is significantly cleaner than it was using my old ShopVac.The black square power supply automatically turns on the vacuum when you have a power tool plugged into it and turn on the tool. I use this feature all the time. Very handy.I would suggest to Fein that they offered a different switch mechanism for the HEPA dust hammer feature (over the black square plug used by the auto-on power supply feature. As-is, the hammer is automatically turned on every time you turn on the machine. With this feature on, it activates a sort of hammer system that bangs the HEPA filter out every 30 seconds or so. This is great if you're collecting fine dust particles because it keeps your HEPA filter cleaner longer. With this turned off and no other filtering, fine dust would gum up your HEPA filter pretty quickly.When the Fein Turbo II is coupled with a Dust Deputy like you see in my first photo, the HEPA hammer feature is not really needed. Most material gets caught in the Dust Deputy. A little breaks through to the filter bag inside the mail unit. Virtually nothing gets to the HEPA filter. I would turn that feature off by default if I could, but I can't. If anyone else uses the vacuum, I need to explain how to turn off the HEPA hammer feature or suffer the continual banging noise in the background.The room you see pictured had a recently demoed ceiling and I was reusing a lot of the 1/2' drywall as part of a new soundproofing project to add mass. The Rotozip I used to cut out the old drywall (vs pulling it down) created a lot of drywall dust. The FeinTurbo II had no trouble cleaning it up - though, unfortunately, the vacuum didn't attach in any way to the Rotozip itself.I was blowing through liner bags quickly before I bought the Dust Deputy (attached) in December 2020. This Dust Deputy unit is a must for me & keeps the cost of operating the Fein HEPA system a lot lower. I fashioned a platform from 3/8" ply to mount the two-bucket Dust Deputy system on top & the assembly works well. The odd shape of the Fein top made securing a custom platform for the Dust Deputy easy. The orange bungie in the back came with the Fein unit. I just pulled it up and over the plywood platform.The hoses you see attached come from two different units. The skinny one is the one that came with the Fein Turbo II. The fat one was cannibalized from my ShopVac. This brings me to my gripe.Fein Turbo II comes with a hose system that is in no way easily adaptable to its environment. The Fein hose and adapters work perfectly together, but try to attach the hose to my Ryobi site table saw, my Dewalt miter saw, my Bosch router and router table, or my Porter and Cable jointer, my DeWalt orbital sander, etc. and you'll find yourself returning to Amazon over and over again to find the right adapters. Even with the collection pictured in the second photo, I don't have a good solution for getting suction in front of my thickness planer and some of the smaller hand power tools. If the unit operated in a Fein vacuum (pun intended) it would get five stars - or if they had an adapter kit that allowed me to connect to the majority of my power tools, I'd advise buying it, then raise my review up to five stars.The 4-step adapter that Fein sells just doesn't get the job done. I think I might use it for my orbital sander, but that's it. If you look closely at the Fein/Dust Deputy assembly photo, you'll notice that I needed to remove couplings to make the 1 3/8" hose fit the Dust Deputy. I had to remove the coupling from the Fein 1 3/8" hose that went to into the vacuum port and essentially "stuff" the ShopVac hose over the hole. I had to "stuff" the Fein hose into the Dust Deputy adapter leading to the cyclone. While all of this works with a little patience and persistence, it's a MacGyver rig.I would like the Fein unit more if it was universally adaptable to all of my tools and shop equipment. At this price point, I can't understand why it didn't come with some universal adapters.Hopefully someone from Fein will see this and say "Hey... we have the kit for you <insert link here>," but in the mean time, you might might to pick up a roll of duct tape and a few adapters if you want this unit to work in a well diversified shop.
