Excellent suction performance thanks to adjustable nozzles
Thanks to its adjustable nozzles, the D300 pool robot has optimised suction performance. The closer the nozzles are to the surface to be cleaned, the better the cleaning performance and results. The suction power is thus adapted to the type of dirt to be picked up.

Intelligent Navigation
BWT pool robots are equipped with the innovative Smart Navigation control system. The integrated gyroscope calculates the optimal route adapted to the pool for fast and efficient cleaning. This way you get the best cleaning performance for your pool.

The Pearl Water Manager is protected against dust and water according to IP68 standard, which means that the station is completely waterproof and dustproof and is suitable for conventional pool depths without restrictions. (Important here is the correct closure / engagement of the loading lid at the upper end of the buoy - seal on groove - to prevent water from penetrating!).
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.
Depending on the frequency of use and duration, calibration is announced via the app or we recommend calibrating the Pearl Water Manager once a year at the beginning of the swimming season. The calibration is carried out with the calibration set and is accompanied step by step by means of the app.
No! Do not use the robot while people are in the pool.
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.
Yes you can leave the Pearl Water Manager under the pool cover or skimmer as long as the Pearl Water Manager cannot get caught, wedged or pulled into any pool components (e.g. automatic pool cover etc.). Some pool covers or skimmer types may experience signal loss/interference over the cover period - depending on the thickness/material of the cover and the type of connection (Wifi and/or Bluetooth). As soon as the Pearl Water Manager leaves the cover, it starts picking up the signal with the smartphone.
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.
The battery charge lasts between 3-6 months in continuous operation and depending on the signal type and strength, true to the motto "One Charge One Season", i.e. an entire (outdoor) pool season.
Attention in the delivery state there are black protective caps on all sensors, these must be removed beforehand (is also displayed in the app). To do this, remove the pink perforated cover of the Pearl Water Manager and pull off the black protective caps. After that, the Pearl Water Manager should work properly. (Recommendation: You can reuse the protective caps for winterising or storing the Pearl Water Manager.)
Yes, this is possible thanks to a multi-user environment. Several pools can be created with one buoy and even releases can be given to the neighbours via QR code in order to see the water values of the pool while one is on holiday (pool sitter).
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).
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
To change the sensors you need the supplied key tool (pink plastic key) to unscrew the sensors (twistlock system). The new sensor is inserted (slight click) and tightened accordingly. (see video)
The automatic pool robot from BWT cleans your pool completely independently and reliably. It circulates the pool contents with significantly less energy consumption than a filter system.
