I am thinking of getting one to help with cat litter and hair that is getting to be frustrating. I would only need it do do one room and a hallway to contain the problem.
I am looking at the 650 and the 760. The difference is only $50 but reviews tend to read more like PR documents than a real breakdown of the differences. It looks like the more expensive one just adds hepa filters (which I don't need) and "lighthouses" for directing the device (which don't seem necessary, at least for the area I am seeking to clean).
Anyone have one, or know someone who does?
