Talking about a maintenance-free means that any damage to the motor or the circular blade will acquire the user to return the automatic secateurs to the shop where a technician will repair the tool. Assigning the maintenance task to the elderly will be a great disadvantage for the tool. It will require the user to acquire knowledge of how the tool works internally, a totally needless task.
Also you are right that we have forgotten to mention where the motor will be. The motor is situated at the front end of the upper handle, right in front of the battery. Since the motor has a cylindrical shape it will only require a small modification on the right side of the handle. Basically a small round extension on the right side.
