Difference with S200 and S300i pool robot
S300i
- 2 instead of 1 active brush
- Energy efficient transformer type "Pro" and not "Eco".
S200
- Not operable with Smartphone or remote control
- As a result, no LED indicator light on the back either
- No caddy or storage system
- Standard cleaning program only
- Filtration system is slightly less advanced, Dolphin s300i features Multi-layer filtration. Dolphin s200 has only 1 filter basket. So you have to choose between the fine filters and coarse filters. Both are included with the robot though.
