I use mine for to clean up a few misc. wood shavings after cleaning my guinea pig's cage and for other small, light duty tasks. It works perfectly for that. I equate it to a Shark vacuum or something along those lines. The fact that it uses the M12 batteries which I have lots of means I can just grab another battery instead of waiting for it to charge.
I wouldn't buy one unless you already have M12 tools. There are better options out there once you factor in the cost of a battery and charger.
