I saw the Mirka unit recently at a flooring show. Talking to the Mirk people at their booth, I was told that Mirka does not make the unit. It is made for them by Nilfisk - who also makes it for Milwaukee. So if you do decide on the unit, you have tha ability do shop price, if that is important to you! Festool makes all of their own tools, including the extractors, which I personally find important for support, warranty, etc. I compared performance of the Mirka and Festool unit and the Festool wins handsomely.
Units with clean/empty bags: Festool 17% higher CFM
Dirty/partially full bags: Festool CFM drops 40%, Mirka CFM drops 59%
Mirka duty cycle rating is 600 hrs for their motor, so that is only 2.5 hrs per day in a typical 250 working day year. Not a lot. If you put a dual operator kit on the unit, the use goes to half or 1.2 hours per day for each operator. That is a pretty light duty cycle for the price they are asking.
Warranty: Festool is a full 3 years, Mirka is 2+1 only if you register your unit.
I always consider after warranty service and parts availabliity. I never worry about Festool, because they make their own products. I get a little concerned with Mirka when you see their track record with tools like CEROS. That thing went to recall and disappeared off the face of the earth. I was told that they had similar issues with the DEROS.
Just to revive this:
This must be the MV-912, not the 1230, which is what they sell now.
I'm not sure if anyone OEM's the 1230 for them.
However, the 1230 has a higher vacuum and CFM rating than the festool (I have both).
CT26/36 E - 138 CFM (3900 l/min) at 96" static water lift (24000pa = 240 mbar)
Mirka 1230 - 158 CFM (4500 l/min) at 100" static water lift (250 mbar).
The US version of the 1230 is a little lower than these (to keep it at 15 amps while still allowing wattage for tooling AFAICT). The spec page they have is wrong. I believe it's 4200 l/min and 240 mbar. I can double check if anyone cares
I also use pneumatic auto-start, which was a pain to find and get installed on the festool, and often didn't work properly (it would keep going after airflow shut off).
The mirka, it's integrated the same way the case holder is, gets in the way of nothing, and works all the time. The only annoyance is that it has a real plug, rather than a hidden relay like the festool. It would have been much nicer than the festool if they had done the relay thing and gotten rid of the plug.
The IAS/LEX related stuff that can attach to the back of the festool is a clear afterthought (and interferes with things). I actually went down the IAS/LEX rabbit hole for a few years and just recently changed back to Mirka after getting tired of the needless specialness of the festool way (it took me all of 20 minutes to make a nicely sleeved coaxial vac + airhose that doesn't require special connectors, etc)
I certainly won't claim using it with air sanding is common use.
However, overall i'm honestly a lot happier with the mirka than i was with the festool.
I still use festool hoses though
