A:Answer The Bobi works best on bare surfaces. Ours constantly gets hung up on our rugs which don't even have tassels. Yes, it will push/smear cat poop and vomit. Bobi is more of a maintenance vacuum cleaner and won't suck up large quantities, so if you have a pile of cat food I would use a traditional vacuum. The Bobi is great for getting underneath certain furniture, though.
