Some of my favorite self-emptying robot vacs are at record-low pricing for Black Friday, including the Roomba Combo j5+ for $399.

Vacuums have come a long way from the cumbersome corded models of decades past, but they’re not exactly…cheap. Thankfully, we’ve spotted lots of Black Friday vacuum deals on all sorts of models—from upright to robotic to hardwood-specific to pet-friendly—many of which we’ve written about before and have tested in our own homes.

Our top pick for the best budget robot, the Roomba i3 Plus Evo, is currently on sale as part of a bundle with iRobot’s separate dedicated mopping bot, the Brava Jet M6. You can get both bots for $399.99, down from $696.18, at Amazon.
