As of Sept. 15, the Shark AV2511AE AI robot vacuum is on sale for $299.99 at Amazon, a 50% discount from its $599.99 list price, saving $300. The robot vacuum features powerful suction that picks up dirt and pet hair on both carpets and hard floors, a self-cleaning brushroll that helps prevent hair wrap, Matrix Clean technology using a precision grid pattern to make multiple passes over messes, and 360° LiDAR navigation that maps your home and detects objects, even in the dark. When the battery runs low during a clean, the vacuum returns to the dock to recharge before picking up where it left off, and it offers up to 90 minutes of runtime. Its bagless self-emptying base can hold up to 60 days of dirt and debris, with no need for disposal bags.
