I have this exact vacuum and have mixed feelings about it after a year or so in use. Mine lives in my reloading room, and is mostly there to clean up messes and pull brass shavings away from a trimmer. On the plus side, it has never exploded, and that is an endearing quality in something that sucks up gun powder and occasionally hot brass trimmings. On the minus side, the suction is just so-so, and while I am not certain this is objectively true, I feel like the suction diminishes with the battery drain. It doesn't seem to particularly like being run for more than 15 minutes continuously, either. Neither of which are your use-case, but I've never even thought to use it with any of my power tools. It doesn't have the capacity to trigger off another tool, and I doubt it would keep up with a router, nor do I think it would be well suited for longer duration sanding, nor have that much suction to pull up anything larger than light sawdust off the shop floor. Plusses on portability and cord-freeness aside, it doesn't even clean my vehicle interiors all that well; shop vac does a much better job of removing Goldfish, old fries, and Oreo crumbs.
I actually plan to replace mine for brass trimming with a CTL SYS, because it can trigger off the trimmer and has more suction on main power. I love most of my Milwaukee tools, but ironically enough, the vacuum sucks, though not in it's intended capacity.
