Why this matters
Marketing names often cover multiple generations. The connector, model code and manufacturer fit list are the reliable purchase checks. A head that looks similar may fail to attach, and smart features need their own support check.
What to do next
- Read the code printed on the handle.
- Search that code in the model finder.
- Open the exact head family and compare the retail pack part number.
