Our Verdict

Roborock H7

LG CordZero A9 [A916, A916BM]

The LG CordZero A9 is better than the Roborock H7. The LG feels better built, has fewer parts needing regular cleaning, makes less noise, and delivers better performance on bare floors and low and high-pile carpets. It exerts a stronger suction force at its floorhead and does a better job cleaning debris in cracks. However, the Roborock does weigh a little bit less, and you can use it as a bagged vacuum.
