Walmart offers the Moneual RYDIS Hybrid Robot Vacuum Cleaner / Dry Mop, model no. MR6550, bundled with a Bissell, Dirt Devil, or Eureka Stick Vacuum Cleaner for $189 with free shipping. (Choose from three select models on the product page.) That's $60 under the lowest total price we could find for the robot vacuum alone elsewhere, although we saw it for $40 less (without the extra vacuum) four weeks ago. This bagless floor vacuum features seven cleaning modes, a washable foam filter, rechargeable battery, and remote control.
