Our Verdict
Shark PowerDetect RV2820ZE
eufy E20
The eufy E20 and the Shark PowerDetect RV2820ZE are pretty evenly matched, with the eufy having a slight advantage in performance over the Shark on most floor surfaces. The Shark adds mopping, though it's mostly ineffective, and both have self-emptying docking stations. But the eufy's obstacle avoidance system is clearly better than Shark's flagship.
