Troubleshooting · Skimmi Troubleshooting
Why isn't the Skimmi charging in a sunny location?
Short answer: The Skimmi may already have a full battery, so check direct sunlight and the app's charging strength before looking for limescale or a battery issue.
Make sure the Skimmi has direct sunlight, then open the app and check the charging strength.

The fix
Step by step.
Your Dolphin Skimmi may not be charging because its battery is already full. With a full battery, the skimmer can use solar power instead of battery power. As sunlight weakens, the battery will power the skimmer again while continuing to charge.
-
Step 1Check direct sunlight
Make sure the Skimmi receives direct sunlight so its battery can recharge. Cold weather and cloudy skies can affect charging.
-
Step 2Check charging strength in the app
If it still is not charging, open the app and note the charging strength.
- Below 5 Watts: Look for limescale buildup on top of the solar panel. If you find residue, gently remove it with diluted citric acid or vinegar.
- Above 5 Watts: If the battery is not gaining charge despite this reading, it may be faulty. Contact Poolbots' pool experts by live chat or phone for help.
Important: This is a solar-powered robot. It needs direct sunlight and enough solar power to charge and operate properly.
