Pool robot D300
Excellent suction power due to adjustable nozzles 
Thanks to the adjustable nozzles, the BWT pool robots have a better suction performance. The closer the nozzles are to the surface to be cleaned, the better the performance. 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 gives you the best cleaning performance for your pool. 

4D filter 
The 4D filter consists of elastic 3D microfibre loops which, combined with the vibrating motion, maximise water flow. The vibration improves suction and prevents the filter from clogging. The 4D filter catches even the smallest impurities. From leaves to grains of sand, so nothing escapes. 

Breezer & Ultimate Power Technology 
BWT pool robots are equipped with Breezer technology, a drive system that offers greater efficiency and resilience. Its two motors and powerful pump make it an extremely reliable robot. This system forms the Ultimate Power, the ideal solution for fast and optimal movement, unparalleled cleaning and unique robustness.

Plug & Play and easy cleaning 
The BWT pool robot starts its programme at the touch of a button - once cleaning is complete, it switches off automatically. The filters can be easily removed and cleaned from above using the bracket. 

Pool Buoy
BWT Pearl Water Manager
The BWT Pearl Water Manager watches over the quality of your water and the safety of your bathers 24 hours a day. This smart pool buoy permanently measures pH, temperature, conductivity and redox potential in real time in both classic chlorine pools and salt water pools

Simple pool water advice 
If treatment is required, you will be notified immediately by the Pearl Water Manager. Continuous monitoring identifies water imbalances and reduces chemical use. Saver, more enjoyable for bathers and more respectful of nature. Additionally, the app gives you a weather forecast for up to 7 days and recommendations for using your pool chemicals based on readings. 

With the app you can get a quick overview of your water quality. It is available for Android and iOS in 10 languages and is compatible with all common smartphones.

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.
