Our Verdict

Roborock E4

Roborock S7

The Roborock S7 is better than the Roborock E4, though the E4 is still a great option if you're on a budget. The E4 has a bigger dustbin that doesn't need to be emptied as often and cleans more effectively on bare floors and low-pile carpets. However, the S7 has a unique carpet detection feature, a more advanced mopping system, a better build quality, and a broader suite of automation features, including virtual boundary markers to prevent it from entering certain areas.
