The emergency stop button (and the child lock) work, but you still have to pry the item out of its claw.

Run TimeScreenshot Roborock Saros Z70 via Adrienne SoAs far as the rest of the robot vacuum goes, the one major difference between the Saros Z70 and the Saros 10R is that the battery life is much shorter on the arm-wielding bot. When the Saros Z70 was running, I deliberately stopped picking up as much as I normally do to see if it got tripped up. Other than a few items that no robot vacuum could have coped with, like my daughter’s doll’s hair, it coped remarkably well.
