Main function is connects to my 36v miter saw Bluetooth aws works great. I also love it because the suction nozzle works great as a floor sweeper so after I've finished all my cuts I can clean my saw and sweep the floor quickly and easily. I also keep it in my pickup truck rather than my trailer so I always have a vacuum even when there's no power. The filtration system is also very good, easy to clean. There is a pre-filter surrounding the paper filter and it works. I've used it for a few trim jobs and most of the time I've been cutting MDF trim. I am considering buying another one for the Makita drywall sander.
