This Roomba robot vacuum is on sale for only $150 for Black Friday

iRobot's entry-level Roomba 104 Vac robot vacuum is available for 40 percent off right now, taking its normal $250 price to a record low of $150. A number of other Roombas are on sale for Black Friday, too.

In iRobot's lineup of robot vacuums, the Roomba 104 sits on the low end, adept at vacuuming up dust and hair, but without the mopping ability of its more expensive Max, Plus or Combo counterparts. The Roomba 104 Vac makes for a great first robot vacuum all the same, though, because of its four levels of powerful suction, and easy-to-use app. Like iRobot's other vacuums, the Roomba 104 maps and navigates your home with LiDAR, which helps it avoid obstacles. And using the Roomba Home app, you can schedule it to clean specific rooms, and even spot-clean particularly dirty spots.
