Technical Malfunction Issues

Multiple users report issues with the Pentair Prowler 920, primarily related to movement failures, electrical problems, and operational inconsistencies, often despite attempts to troubleshoot and clean the device.

  • Movement Failures: Many users experience the robot moving only briefly (5-10 seconds) before stopping or reversing. This issue is frequently reported and persists even after attempts to clean or replace parts.
  • Power and Electrical Issues: Several reports mention the unit not turning on or the control panel malfunctioning, with some users noting that the control panel remains operational while the robot does not. These issues suggest potential electrical faults within the robot itself.
  • Flashing Lights and Malfunctions: Users have reported instances where the unit powers on with flashing lights but fails to move, indicating possible motor or internal component failures.
  • General Failure to Operate: A recurring theme is the inability of the unit to function, with users stating that it turns on but does not move, regardless of cleaning or checking for debris.

Power and Charging Issues

Multiple reports indicate power supply issues with vacuum units, including shutdowns, intermittent failures, and electrical trips, primarily occurring after prolonged use or under specific conditions.

  • Vacuum Shutdowns: Vacuums consistently run for about 15 seconds before shutting down, indicating a potential power supply or control panel malfunction.
  • Power Supply Failures: Intermittent issues with power supplies not turning on or shutting off unexpectedly, even after trying different outlets.
  • Breaker Trips: Reports of breakers being thrown, particularly when using the equipment for extended periods, suggesting possible overload or short-circuiting issues.
  • Control Panel Issues: Control panels failing to power on, with no indicators showing functionality despite checks on electrical connections.
  • GFI Trips: Specific mention of GFI plugs being tripped after about 15 minutes of operation, requiring resets, indicating a recurring electrical fault.

Performance Issues

Multiple users report issues with the Prowler 920, primarily related to suction, movement, and cleaning efficiency, indicating a pattern of mechanical performance problems affecting pool maintenance.

  • Movement Issues: Several reports indicate the Prowler 920 moves only a short distance (3 feet) before stopping, does not turn, and struggles to climb walls. Users mention that lifting the unit allows it to move freely.
  • Suction Problems: Users consistently report inadequate suction, with the unit failing to pick up debris effectively. Some mention that the device goes over debris but does not collect it, and others note debris being expelled from the discharge chute.

  3. My Pentair Prowler 920 isn’t even 12 months old. I went to use it one day and it moves forward for 5 -10 second, then reverses back and stops. I tried half a dozen times with the same thing happening. Took it out and thought that maybe one of the tracks seems a little loose (or looser than the other anyway) so I replaced the track but it still does the same thing. Anybody know what the problem is and how to fix this it?

  12. I turn it on at the panel, the blue light comes on the machine in the pool, but it does not move at all. I’ve taken it completely apart and took the motor out. Everything looks fine with no debris and tracks move fine. I can only assume it’s the motor.

  20. This just started happening and now happens every time i turn it on. The unit movers for about 5 or 10 seconds then stops. I have turned the control off then back on multiple times, and have unplugged the control unit from power completely.

    The unit is clean, no sticks or debris.

  24. My Prowler does not turn on. The control panel turns on and turns off straight away. When I disconnect the robot from the control panel, the control panel stays on. It seems like the issue is the robot cleaner itself. Any suggestion how to fix this issue?
