I don't like to eat or smoke at my desk so I bought this little ladybug vacuum in hopes it would help remove ash and crumbs. I've had it for two months now, no problems, and I really like it! Small, lightweight debris like ash can be blasted rather than sucked in depending on where it is, but for the most part they suck in everything in their path. I highly recommend it and plan on getting another one for the kitchen.
