This part is installed by pool service technicians or experienced pool equipment owners performing routine wear-part replacement on Dolphin robotic units.
These tracks are designed for use with Dolphin Active Series robotic pool cleaners in residential pool applications. They are a direct OEM-style replacement for the drive track assembly on the Active Series platform. Compatible models include the Dolphin Active S50, S100, S200, S300, S300i, and S400. Installation requires no special tooling beyond basic disassembly of the cleaner chassis to access and swap the track units.
Designed for the Dolphin Active Series robotic pool cleaners, specifically the S50, S100, S200, S300, S300i, and S400 models.
Track replacement on Dolphin robotic pool cleaners is typically performed by pool service technicians. Before servicing, remove the unit from the water and disconnect it from the power supply unit. Follow the manufacturer's disassembly sequence to remove the worn tracks and seat the replacements fully onto the drive wheels before reassembly. Inspect drive wheel condition at the time of track replacement to identify any additional wear components.
