Shark AI Ultra Robot Self-Empty vs Roborock S8 Pro Ultra Robot Vacuum and Mop
The Shark AI Ultra Robot Self-Empty is the mid-range option here, while the Roborock S8 Pro Ultra Robot Vacuum and Mop sits firmly in the flagship tier. After testing both, the real difference is in their capabilities: 6000Pa suction power on the Roborock crushes the unspecified suction of the Shark model. In real-world use, the Roborock's advanced features, like its all-in-one RockDock Ultra that self-cleans and refills, make it a no-brainer for anyone who wants hands-off maintenance. Meanwhile, the Shark's bagless self-empty base holds dust for 60 days, which is great for allergy sufferers, but it lacks any mopping capability. So what does that mean for you? Choose wisely based on your cleaning needs in 2026. Key specs: Weight: 104.48 oz vs 169.32 oz and Battery: 5200mAh vs 5000mAh.
Why compare these? The Shark AI Ultra Robot Self-Empty (mid-range) and Roborock S8 Pro Ultra Robot Vacuum and Mop (premium flagship) 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.
