Safety Guidelines
- You may experience some discomfort, such as a tingling sensation or minor bleeding, when using this product for the first time. Start by using the Sensitive Mode for one to two weeks to allow your teeth to adjust. If the discomfort persists beyond two weeks, it may indicate an abnormality in your gums. In this case, or if you experience any other discomfort, you should stop using this toothbrush and consult your dentist.
- If you are undergoing dental treatment—such as orthodontic treatment, dental restorations, or dental implants—please use this product under the guidance of your dentist.
- This product is intended solely for brushing teeth. Do not use it for any purpose other than oral hygiene. Please use accessories such as chargers and brush heads manufactured by Erigo.
- Individuals with physical, sensory, or mental disabilities or impairments must be supervised or guided by another person when using this product. Do not allow children to play with this product.
- Do not place the toothbrush where it could fall. If it falls, immediately check the product for damage to ensure its waterproof performance. If you are unsure, please contact the after-sales service center.
- Do not modify or repair the product yourself, as these actions may result in fire, electric shock, or other injuries.

Keep it clean
This product is fully waterproof and easy to clean; please do not leave it submerged for long periods of time. Please return it to its base after use.
The wireless charging stand is resistant to everyday splashes. To clean it, unplug the charging cable and wipe it down with a damp cloth. Wait until it is completely dry before plugging the charging cable back in. Do not submerge the stand completely in water.
How to Charge
Remove the silicone plug from the back of the base and plug in the power cord. Place the main unit into the base; the white status light will begin to flash.
A single full charge provides approximately 45 to 60 days of battery life.
When the red indicator light flashes to indicate low voltage, please recharge the device promptly; the light will turn off once charging is complete.
Toothbrush Head Features
Yellow: Softest—Sensitive
Green: Medium—Clean
Red: Hardest—Polished
Ailigo offers three different bristle hardnesses to suit the needs of different people.
We recommend using the Sensitive or Clean brush heads for daily use, and the Polishing brush head once a week to thoroughly remove plaque.

When replacing the brush head, hold it firmly and apply pressure to release the safety latch before gently pulling it out.
*Be sure to check the orientation before installing the brush head. Incorrect orientation may damage the latch; do not force it into place.
