@Janza So sorry that the RoboVac 11S cannot be turned on normally. If the power switch underneath the machine is turned on at the ‘I’ position (‘I’ mean ON, ‘O’ means Off), it seems there’s something wrong with the switch. Please contact us at firstname.lastname@example.org with the ticket and the receipt to further resolve the problem. It’s recommended to offer a short video to show the status of the power switch, beeps etc to accelerate the process of troubleshooting.
Thank you for your time and look forward to hearing from you.
