2019 – Relaunch of the brand identity

New brand image and new products.

Our brand identity is being revised. The premium standard of our appliances can now be experienced more than ever in the visual perception of our brand.

proliner natur

The successor to the pool floor cleaning device with high-pressure unit, which was launched in 2014.

The proliner natur has an integrated rotor, which is operated at high pressure in order to loosen the stubborn biofilm from the pool floor, effectively vacuum it, transport it into the filter box and filter it out. The dirt is not only loosened, but also removed from the pool at the same time.

proliner tube

In the case ofvery heavily polluted pools, the filter capacity in the robot is not sufficient to clean the dirty water. The filters would be clogged in no time. This is where the proliner tube comes in.

The cleaning device does not have an integrated filter box like the other Mariner 3S models. The dirty water is pumped out of the basin via an additional hose. The water is then filtered outside of the pool orfed directly to the waste water.

2018 – proliner navi3 & puromat

New generation of devices.

The mariner 3S navigator II and topliner are replaced by the new model proliner navi3. 6 lamellar filter cartridges with the largest filter surface available on the market relieve the stationary filter system. The proliner navi3 is equipped with a High tech Sensor and rotating brushes. In addition to the driving patterns N, H and X, an innovative segmental cleaning of the pool is now possible. Strong suction power, high cleaning efficiency, the largest filter capacity, intelligent automatic cleaning and high ease of use.

With the introduction of the new large filter cartridges, the filter cleaning device Puromat has been redesigned. The cleaning technique remains the same. What is new is that 3 filter cartridges can be cleaned at the same time. The Puromat filter cleaner can be manoeuvred by tilting on its wheels and the widened foot makes it easier to place it on a drain grate.

After a successful market launch in Switzerland, the proliner navi3 presents itself to an international trade audience at the INTERBAD fair in Stuttgart.

2017 – Subsidiary Company in Italy

Bella Italia.

During May 2017 the company Mariner 3S Italia Srl has been founded. This gives the possibility to provide a better service to the mariner 3S customers located in Italy.

proliner & proliner plus

For large swimming pools over 25 meters length, which are smaller than olympic pools, and for thermal SPAS, Mariner 3S has developed the product line proliner. The proliner is capable of travel pattern X. The proliner plus has the basic sensor and is capable of travel patterns H, N and X. These high-performance cleaning robots for public and private baths combine powerful suction power, high cleaning efficiency, large filter capacity, intelligent automatic operation and ease of use in a compact robot which continues the clubliner series.

After a successful product presentation at the fair INTERBAD Stuttgart and AQUALIE Lyon in November 2016 the successive commercial launch worldwide of the proliner robots starts in April 2017.

2014 – Pool-floor cleaning appliance with high pressure unit

High pressure for the natural pool.

When it comes to the cleaning of organic or natural pools, they have the same requirements as conventional pools. The guests want a clean swimming pool.

In such pools, the water treatement works without chemical additives, with the effect that a bigger cleaning effort is needed to remove the biofilm from the pool floor. Due to customer demand, Mariner 3S AG decided to develop a pool cleaner with an integrated high pressure device. As a result, it is now possible to dissolve the persistent biofilm from the pool floor, effectively aspirate, transport into the filter box and filter it out. The dirt is not only dissolved, but removed from the pool.

2009 – Formation of Mariner 3S AG

Internal restructuring.

After over 36 years of working together the owners decided to make a plan for succession, with the aim of keeping the company in the family.
