My impeller is clogged – How do I clean it?

From Maytronics support, updated 2026-04-26, rewritten for clarity. Parts that fix it are below.

The fix

Step by step.

  1. Make sure the power supply is unplugged from the outlet.
  2. If you notice debris trapped in the impeller, open the impeller, remove the debris, and reassemble it. (Caution: Use a Phillips-head screwdriver; do not use a power drill.)
  3. If your robot model has grilles on the sides, check for visible debris there as well.
