What to know.

Nautilus CC Plus with Climbing Rings

Please follow the steps below for proper installation:

(The following steps are applicable for all models that have climbing rings)

  1. Wet the climbing rings in the pool or soak them in water for 10 minutes until they are fully soaked.

  2. Remove the robot from the pool, and turn the robot upside down.

  3. Make sure the power supply is unplugged from the outlet.

  4. Use a flathead screwdriver to release the brush from it on both sides.

  5. Remove the brush.

  6. Remove the climbing rings.

  7. Soak the new climbing rings in water so they are flexible. Take the new climbing rings and work them onto the brushes.

  8. Once the climbing rings are in place, slide the brush back into its sockets and push it into place.
