Our Verdict

Roborock E4

bObsweep Bob Pro

The Roborock E4 is a better overall robot vacuum than the bObsweep Bob Pro. The Roborock is better built, is easier to maintain, and has a larger dirt compartment. It also clears debris more effectively on all surfaces and doesn't struggle at all with pet hair. Conversely, the bObsweep is a little smaller and comes with a remote controller.
