How often should I replace the shaving heads of my Philips Norelco shaver?

Philips Norelco recommends replacing the shaving heads approximately every twelve months for optimal performance. This timeframe can vary depending on personal usage habits and hair type. If you notice that your shaver is pulling on hair or not providing a close shave, it may be time to replace the shaving heads sooner. Additionally, users should keep an eye out for decreased battery life or difficulty cleaning the heads, as these can also indicate that a replacement is necessary. Remember, maintaining the cleanliness of your shaver can extend the life of the shaving heads, so regular cleaning is also important.
