Shark AI Ultra Robot Self-Empty vs Roborock S7 Max Ultra Robot Vacuum & Mop
If you're after a robot vacuum that excels in hands-free maintenance, the Roborock S7 Max Ultra Robot Vacuum & Mop is the standout choice. With its RockDock™ Ultra system, it handles emptying, washing, and refilling automatically, while the Shark AI Ultra Robot Self-Empty offers a bagless solution but lacks mopping capabilities altogether. After testing both, it’s clear that the Roborock's 180-minute runtime versus the Shark's 120 minutes means less downtime for charging, making it more efficient for larger homes. Plus, the Roborock's impressive 5,500 Pa suction power makes it a pro at tackling carpets and stubborn stains, whereas the Shark falls short on deep cleaning performance with unspecified suction metrics.
