I was so excited to receive my bObsweep. I am sorry to say though that it did not meet my expectations. It cleaned sporadically, which I am sure is just a small programming issue; however, it constantly got stuck on most floor level changes depending on the angle it approached it, and it usually took forever to find the docking station. Further after cleaning a small bare floor area, I ran my hand over it only to find it did a poor job, as my hand felt some grit and I had dust all over my hand. Also the dirt bin barely had anything in it, which was odd. This certainly will not influence me shopping at Wayfair.com  .... awesome shopping site!
