iRobot's Roomba 694 is back on sale for $179 ahead of Black Friday

Black Friday is good time to pick up a robot vacuum for less than usual, especially considering these can be some of the most expensive smart home gadgets out there. Thankfully, you don't have to spend an arm and a leg to get a decent one. Right now, iRobot's affordable Roomba 694 is even cheaper than usual at $179, which is $95 off its normal price. Typically priced at $274, the Roomba 694 impressed us with its sleek design, good suction power that cleans carpeted and hard floors well and its ability to navigate around most household objects. There are more expensive machines that do a superior job sucking up pet hair, but the 694 was surprisingly good at it, too.
