FAQ and Troubleshooting
What should I do if the device is not connecting to Wi-Fi?
If the Wi-Fi indicator light is not turning blue, ensure that the Wi-Fi network settings are correct and try restarting the device.
How do I know when the battery is low?
The LED indicator will show a flashing blue light when the battery level is below 50% and a flashing red light when it's below 25%.
Why is the device not cleaning for the full 12 hours?
The device runs up to 12 hours in optimal sunlight, 8 hours in winter, and 6 hours in low light. If the fully charged battery seems insufficient, contact customer service.
Why isn't my device picking up floating debris?
Plese empty the debris basket regularly to prevent clogging and ensure optimal cleaning. Check for tangled thin, long objects between the roller shaft and basket.
Why has the speed of my device slowed down?
