Amazon offers the Neato XV Signature Pro Pet & Allergy Robot Vacuum Cleaner, model no. 9450080, for $299.99 with free shipping. (consumerelectronicscostsavers via eBay charges the same.) That's tied with our mention from a week ago and the lowest total price we could find now by $27. It works on wood, tile, carpet, and vinyl and features LaserSmart mapping and navigation, two high-performance filters, and easy-to-schedule automatic cleaning.
