I bought the Shark Detect Pro three days ago. It could not disappoint me any more. I have a toddler and two cats in a relatively small apartment, so crumbs/litter end up EVERYWHERE. It does NOT pick up any of the litter whatsoever. It just pushes it around. I turned up the power full blast, and it would get a few granules and just push the rest around. I lift up the vacuum and it just spews a bunch of litter everywhere. The same thing happens as I turn it off. This item is awful.
