re: Wife wants a robot vac.... but does she need the mop instead?

I had a neato xv-21 and it died after about 18-months, but I had the 3-year replacement warranty and they just gave me my full purchase price back. I'm getting a neato botvac D80 with the credit as a replacement. The design flaws in the xv-21 have been corrected in the botvac series. I'm also getting the irobot scooba for my kitchen and dining area to mop every couple of days after the neato runs. The mop your are talking about just pushes a wet rag around I think, the scooba actually mops.

Best advice I can give you is buy the longest warranty you can for it.
