Title: This Shark Bites...the dust!
Review: The Ultra Shark seemed like a really neat item. It vacuumed the baseboards on the walls, and picked up dust and hair, which were not visible to the eye. After about two weeks of use, the engine/motor would make grinding noises. A week later, it just stopped. It was charged, then re-charged, but still didn't work. It made a humming noise, and that's all. We cleaned it, re-inserted batteries, we did everything! It just doesn't work. ...
