Roomba Combo j7+ showing “Clean Base solid red: bag full, missing or not detected” has a specific manufacturer-backed troubleshooting path. Match the exact light, sound or behaviour before cleaning, resetting or ordering anything. Confirm “Clean Base solid red: bag full, missing or not detected” exactly, including the full number, colour, flash order, spoken phrase or screen text. If any element differs, use the guide for that other indication instead. iRobot — Clean Base bag replacement documents this condition for Roomba Combo j7+. It identifies the branch to test, but it does not by itself prove that a battery, motor, board, sensor, dock or replaceable part has failed. Unplug the Clean Base, open its lid and replace a full bag or slide the correct bag card fully into both guide rails. Confirm that the robot has the evacuation-port bin and close the lid firmly before restoring power. Power the robot off and remove it from the dock before turning it over or touching a moving part. Keep charging contacts dry and never open the battery pack or electronics housing. Run only one normal start, charge or cleaning cycle after the documented check. If “Clean Base solid red: bag full, missing or not detected” returns unchanged, record the code, model and serial number and contact authorised iRobot support instead of repeating resets or guessing a part.
