As one of its daily deals, 1Sale again offers the refurbished Neato All-Floor Robotic Vacuum System, model no. XV-12, for $149.99 with free shipping. That's tied with last month's mention as the best price we've seen. (It's also a current low for a refurb by $35.) It works on most floors and features a laser-based Room Positioning System that allows it to avoid obstacles while vacuuming a room. It also includes a charging base, two filters, and a six-foot boundary marker. Deal ends today.
A 90-day warranty is included, although it's unclear who backs it. Note that it has an estimated ship time of two to three weeks.
