I have an Mirka Deros CV 650 since a few years back and my only complaint is that I should have invested in one earlier. They are expensive, but it is worth the money in the long run.
The "dust free" concept with Mirka Autonet/Abranet is truly a dust free sanding concept. With P80 does it take about 15-20h to strip the Gelcote from the wings of a 15m glider and there are literally no dust in the workshop when the job is done. I have used the machine though all the steps from removal of gelcoat to polishing the new PU-paint on my glider. Also use the machine it for applying and removal of liquid hardvax as the yearly maintenance och both glider and trailer, is saves both time and pain in the back. There have also been used for misc projects as building a kayak and renovating furnitures. It works for both for dry sanding, wet sanding (Autonet P400+ and Abralon P1000+) as for polishing.

Buy one, you will love it!

But take care, an orbital sander used the wrong way can destroy a glider in minutes. Here is an guide of do and don’t with an orbital sander:
