Early shutoffs point to a power or safety fault: a tripped GFCI outlet, a power supply overheating in direct sun, a full-filter safety cutoff, or a damaged cord. Move the power supply to shade, plug directly into a working GFCI, empty the filter, and inspect the cord for damage.
Start with power and the outlet
Plug the power supply directly into a working, properly grounded GFCI outlet — not an extension cord or a questionable outdoor plug — and confirm it hasn’t tripped. Voltage drop is a leading cause of early shutoffs; see our guide on why extension cords cause problems for robots.
Rule out heat
A power supply cooking in direct summer sun can hit a thermal cutoff and pause the robot to protect itself. Set it in the shade with airflow around it, off the hot deck, and try again once it cools.
Filter and cord
Many robots stop when the filter is full as a protective measure — empty it. Then inspect the floating cord end to end for cuts, kinks, or a loose connector, any of which can interrupt power mid-cycle. Reseat the cord connection firmly.
Reset and retest
Unplug the power supply for 30 seconds, plug it back in, and run a fresh cycle. If it still stops after all of that, it may be an internal or power-supply fault. As an authorized dealer we can help with warranty service — contact our pool experts with your model and the steps you’ve already tried.
