So, not only unable to source replacement bags, now the machine's AI function has failed so it moves a metre from the base station and then stops. Followed instructions "turn off and on" and contacted the service chat. Unable to talk to a person and forced through electronic chat system. Frustrating. Samsung say they will send out an engineer. I here nothing. I contact engineer service who say that they do not fix this machine and keep returning the referral back to samsung. Argghh. Cannot contact Samsung by phone for smart things. The Samsung chat as they are too busy. Frustrating machine and frustrating support from Samsung.
