eufy RoboVac 11S MAX vs Shark AI Ultra Robot Self-Empty
In real-world use, the eufy’s 2000Pa suction power crushes dirt on carpets, but its random navigation can leave spots untouched, making cleaning less efficient. On the flip side, the Shark AI Ultra boasts a self-emptying base that holds debris for up to 60 days, eliminating frequent emptying. With its precise LiDAR navigation, it covers more ground than the eufy, which can only bounce around randomly. If you prioritize convenience and efficiency, the numbers tell a compelling story. Key specs: Weight: 91.71 oz vs 104.48 oz and Runtime: 100 min vs 120 min.
Why compare these? The eufy RoboVac 11S MAX (budget-friendly) and Shark AI Ultra Robot Self-Empty (mid-range) represent different approaches to robot vacuums. While they may appeal to different budgets, many buyers consider both options. This 2026 comparison helps you decide if the differences justify the price gap.
