Please don't worry, it is necessary to stay on the surface for 15-25 seconds until water flows out from the cleaner nozzles to the swimming pool before sinking to the bottom of the swimming pool

No, you can’t. Please turn off the pool cleaner and clean its charging ports before charging.

Please pay more attention to this problem. Please remember that you should put the robot pool cleaner into the water before power it on, which can protect the wheels and the motors and extend their life.

Put into or lift out from the pool with the cleaner bottom toward the wall to avoid any possible scratch to the pool wall.
