Shark's robot vacuums often get most of the Shark-related attention during Black Friday because they're one of the most-known Roomba alternatives.

Need another selling point? This Shark vacuum's collection bin can hold up to 60 days' worth of dust and debris. That means you could go as long as two months without having to clean it out, saving you even more time.

This robot vacuum is a lot like having a meticulous housekeeper that works for free. You can program it to avoid certain obstacles in your home, or you can rely on its Matrix Clean system. Instead of random bumper car patterns, it maps your home with LiDAR and methodically cleans in a grid, making sure no dirt or debris is left behind.
