Hi there, Thank you for sharing your feedback with us. We are sorry to hear that your shaver head pops out while cleaning. We would like to recommend you to please follow the instructions below on how to clean your Shaver perfectly without any hassle. The very first step is to switch on the shaver. After turning it on, rinse the shaving unit under a warm tap. Then, switch off the shaver. Press the release button to open the shaving unit. Please keep in mind that if you are cleaning the head by removing the blade, each shaving head consists of a cutter and a guard. Please keep in mind that the cutter and guard are not interchangeable. So make sure you keep them together. Now, rinse the hair chamber under a warm tap. Rinse the shaving head holder under a warm tap. Carefully shake off excess water and let the shaving head holder air-dry completely. Close the shaving unit. You can also refer to the user manual on how to clean your shaver perfectly. We hope this makes your experience better. If not, please reach out to us via Social Media. We’re available on Facebook (@Philips) and Twitter (@PhilipsCare). Don’t worry, if you don’t use Social Media, you can also reach out to us via the contact page: www.Philips.com/contact. Hope to speak to you soon! Best regards, Philips Consumer Care
