Robot vacuums are one of the few sci-fi predictions that more or less delivered — there actually are autonomous machines that can help keep your home clean. We've tested over a dozen robot vacs, and right now our top recommendation for a budget dirt sucker, iRobot's Roomba 694, is $95 off both at Amazon and through iRobot's site. Usually $275, the 694 is just $179 right now, which matches the all time low it dropped to a few times previously. The deal is part of a wider robot vacuum sale with discounts ranging up to $300, depending on which model you pick. If you've been thinking of adding one of these smart devices to your life, this might be a good time to snap one up.
