Thank you for sharing your feedback with us! We completely understand how important it is to keep the inside of your water flosser clean, and we appreciate the opportunity to help clarify how to remove the tank.
The water tank on our Compact Water Flosser is designed with a secure, tight seal to prevent any leaks during use, which can make it feel locked in place at first. You can easily detach the tank for cleaning by holding the upper main body of the device firmly with one hand while giving the water tank a firm twist and a downward pull to release it from its locking notches.
Inside, you will see the small silicone suction tube that draws up the water—just be careful not to misplace this piece while rinsing. Once cleaned and dried, simply align the tank back with the upper body and click it securely back into place to maintain that watertight seal.
We want to make sure your experience is seamless. If you have any questions, need further clarifications, or would like us to share a video demonstration to help guide you through this process, please reach out directly to our customer care team. You can call us at 866-421-0309 or email us at contact@gurunanda.com. We are always here to help!
