A:Answer Yes, but it's light weight, Hence, the robot often pushes it slightly out of alignment when docking . Then it backs up, makes a few turns, and tries to dock, again.
This can repeat four or more times, before it finally succeeds in docking straight-on and then charging, but it does always get there, eventually.
The first couple of times it's amusing, but then it gets frustrating to see [and hear] these repeated attempts, so you either pick it up and put it on the dock yourself or leave the room for somewhere where you won't hear it.
In the end, it always seems to work, as long as it hasn't run out of juice, first. It's happy to sweep again, in a couple of hours.
Solution: run it when you're not home.
