A Zodiac G2 Weight Replacement Kit is a set of weights used to adjust the buoyancy of a Zodiac G2 pool or spa cleaning system. The weights are typically made of a durable material such as lead or steel and are used to fine-tune the balance of the cleaner. The weights are placed inside the cleaner's body and can be adjusted to achieve the desired level of buoyancy. This allows the cleaner to navigate through different parts of the pool or spa and to stay on the bottom or other areas to clean. The Zodiac G2 Weight Replacement Kit is designed specifically for use with the Zodiac G2 cleaner and it is an important part of the pool or spa cleaning system. It helps to ensure that the cleaner is able to navigate through the pool or spa effectively and clean all areas.
