Black Friday marks a good time to find a ton of robot and stick vacuums on sale, but you don't have to wait to score the holiday deals. (In fact, we've already spotted great early Black Friday sales you don't want to miss.) One of our favorite robot vacuum brands, Roborock, has discounts live ahead of its official Black Friday sale, which kicks off November 19. Two great picks include the Roborock Qrevo 2 Pro (one of my top vacuums overall) and the Roborock Qrevo Curv 2.
