For reliable use of the Mariner 3S cleaning devices, we recommend that you carry out maintenance service periodically. Maintenance will extend the life of your unit. Your device is exposed to harsh conditions during its work in the water. Regular inspection protects against damage.

During maintenance, we check the condition of the wearing parts and the sealing components. If the wearing parts are badly worn, they can have a negative influence on the function and performance of your unit. A water ingress leads to an interruption of operation, damages the components and leads to high consequential costs. We do everything we can to prevent this.

Check with your  Mariner 3S Service Centre in your area about the possibility of carrying out maintenance works.

Mariner 3S has a large stock of spare parts and guarantees the supply of spare parts for at least 10 years after buying a new unit.

You can find the spare parts for your appliance in the operating instructions supplied, on the Videos & Instructions page or by contacting your local authorised dealer.

Mariner 3S endeavours to carry out repairs as quickly as possible. In cases of hardship, loan units can be made available.

We offer you the opportunity to try out our products and familiarise yourself with their many benefits during a free device demonstration in your swimming pool. Of course, we will also provide you with comprehensive advice to help you find the optimum cleaning solution for your swimming pool.
