A self-emptying robot vacuum cleaner is usually preferable to one without this feature, as you won’t have to keep buying garbage bags for it. The base of this one holds up to 60 days of mud, so you may only need to empty it every few months. It has a HEPA filtration system that Shark claims can capture and trap up to 99.97 percent of dust and allergens.

The AV2501AE will run for up to 120 minutes on a single charge. If that’s not enough to cover your home, it will return to its base, recharge, and then pick up where it left off. The vacuum uses a matrix grid approach and makes multiple passes through debris and dirt to pick up as much of it as possible. The device uses LiDAR vision to map your home and avoid objects in its path. You’ll be able to set up a cleaning schedule or start an ad hoc cleaning through the app or through an Alexa or Google Assistant voice command.
