Buy Happier via eBay offers the refurbished Evolution Robotics Mint Automatic Hard Floor Cleaner
, model no. 4200, for $129
with free shipping
. That's $6 below last week's mention of a new one and $51 under the lowest total price we could find for a new one. (It's also tied as the best price we've ever seen for this device.) This robot sweeps and mops.
A 3-year Buy Happier warranty applies.
