Excellent suction performance due to adjustable nozzles
Thanks to the adjustable nozzles, BWT pool robots have a better suction performance (19 m3/hour < 47,500 l/cycle). The performance is higher the closer the nozzles are to the surface to be cleaned. The suction power thus adapts to the type of contamination to be picked up.

Smart Navigation
BWT pool robots are equipped with the innovative and intelligent Smart Navigation control system. The built-in gyroscope calculates the optimal route adapted to the respective pool for fast and efficient cleaning. This gives you the best cleaning power for your pool.

4D filter
The 4D filter technology, consisting of a filter insert with an elastic 3D loop fabric in the 4th dimension, filters every impurity out of your water through additional vibration. From a small grain of sand to a leaf.

Plug & Play and easy cleaning
With just one push of a button, the BWT pool robot starts its programme - after cleaning is complete, it switches off automatically. The filters can be removed and cleaned simply by pressing a button from above.

Yes, the BWT pool robot can be operated up to a salt content of 4000 ppm.
Note: The robot should be rinsed thoroughly with fresh water after each operation.
No! Do not use the robot while people are in the pool.
With the free [email protected] app, you can control your BWT pool robot manually and change all parameters, such as the cleaning time or the type of cleaning. Another practical feature is the delayed start-up of the robot - this allows any dirt that is stirred up to settle before the robot starts cleaning.
Simply place it in the water and let it float. The brushes automatically fill up with water. Then it sinks again as usual. You can speed this up by kneading the brushes under water.
The BWT pool robot is suitable for a water depth of up to 4 m.
No. The BWT pool robot has the unique 4D filter system, which absorbs and filters the usual dirt in a pool in the best possible way.
Ideally on a BWT transport trolley/caddy provided for this purpose. The rollers should be stored freely.
No. The BWT pool robot cleans and filters completely independently with its unique 4D filter system.
Yes. BWT pool robots are suitable for all common pool surfaces (PVC, ceramic, stainless steel and polyester).
We recommend our BWT pool robot D300 for operation in medium-sized pools.

Expert recommendation: Pools, regardless of shape, regardless of stairs, up to a size of 7.5 x 4 m or approx. 30 m². Also suitable for pools with beach access.
Basically, it is sufficient to clean and check your BWT pool robot regularly during daily use. 

  • Be sure to disconnect the device from the power supply during cleaning
  • Clean the filters thoroughly after each use.
  • Check the drive system and the suction motor regularly and, if necessary, free them from impurities/foreign bodies
  • Unplug the floating cable at the transformer and lay it together starting from the robot. Occasionally, lay the cable out in the sun and leave it for a few hours before reassembling it
With its 4D filter system, the BWT pool robot D300 cleans the floor, the water line and, after "command" via the free app, also the walls of the pool. Thanks to its clever navigation system, the BWT D300 achieves optimum, energy-saving cleaning performance.
