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

A vacuum so nice it appeared in our best-in-class guide twice, the Gen5detect is notable for its 70-minute run time, nifty add-ons, and masterful ability to suck up pet hair. You’ll save more than $100 if you buy it now.

If you have a large house or if you want to cut down on cleaning time, finding a powerful vacuum cleaner is essential. When it comes to quality and effectiveness, Dyson is a British brand that immediately springs to mind.
