I ordered this pool cleaner new from Marina Pool, Spa and Patio in 2020.  It recently stopped working, and was diagnosed as a motor failure.  Everything except the motor is in good working condition.  The power supply works great, the filter basket is in good shape, etc.  

It is the Pentair Warrior SE - according to Marina, it is a rebranded Maytronics unit, "Compare to the Active 20, S200, Explorer E30, Triton PS, Prowler 920".  Please do your research on exactly which Maytronics robots are identical to, or compatible with the Pentair Warrior SE.
