This Roomba robot vacuum and mop is 46 percent off right now

The Roomba Y0140 robot vacuum and mop combo unit is on sale for 149 via Amazon. This represents a discount of 46 percent, as it typically costs 250. It's rare we see robots that can vacuum and mop at this price point. The Y0140 is actually a combo version of the vacuum-only Q0120, which topped our list of the best robot vacuums on a budget. We loved the iconic design and the surprisingly-robust suction power.
