Dan,
Here's my take on The Extractors:
Customers often ask why so much for a shop vac? It's not a even fair fight to compare them to a shop vac. IMHO a shop vac is bucket with a motor and a filter (word used lightly). They are also very good for making high pitched screaming sounds, producing dust clouds when emptied, catching on obstacles, and flipping over on their side.
The Festool extractors work great for cleanup. I'd recommend the D36 hose because the D27 is a bit too small and will clog. The smartest way to get the hose is with one of the cleaning sets. ( Installer 454767, Workshop 454767, Universal 454769 has standard hose , not AS). Like Bill-E said, I use a broom for the really big stuff.
Folks question the disposable bags, but once you use the system and see how well it actually works, it's a no brainer. (We've all suffered enough with mediocrity with our tools long enough.) Like everone else says, it's amazing how packed the bags can get and still function.
Here's a couple of other things to consider that can be over looked:
The wheels are smooth and the unit "comes" when you pull it. Probably not the best way to move it but in the real world we all do. You would really have to work to tip one over. The hose says firmly attached to tool and the CT. You'll find this a refreshing change to what you're used to.
these things are powerful. Static water lift measures maximum pressure at zero air flow. Most of the big industrial shop vac top out at max of 60" The CT Mini is 80" and the CT 22/33 is 90"
The CT motor is sealed from the rest of the unit. Gaskets seal the bag compartment and there is even an O ring seal around filter rake.
The rake helps clean the HEPA filters INSIDE the unit.
I've had mine for about 3 yrs and am continually amazed how well it works. It's so quiet, If other tools are running you can forget it is on. My old shop vac's have found a use as a rolling trash can!
You won't regret getting an Extractor. Pick the size that works for you. If you're just in your shop, consider CT33, CT 22 for more mobility and use on sites, or Mini or Midi for a small but really powerful, portable use.
Note new CT MIDI will be out May 1.
