The blue handle is essential for activating the brake switches on Cobi. If the handle is not fully pushed down, the brake switches may not be pressed, which can lead to a traction motor error or Cobi staying still. It is crucial to make sure that the blue handle is fully engaged.
If the lid of the Cobi is not closed properly, it can cause issues with suction. This may result in low or no suction, leading to ineffective cleaning. It is necessary to ensure that the lid is securely closed to maintain proper suction functionality.
Note: Be sure to "click" the lid and handle tightly into place.
