The maintenance answers your support inbox will receive, written so you can paste them into a manual.
The Tank And The Attachments
The water tank detaches. The attachments themselves cannot be cleaned internally - they are replaced. Tell users that plainly in the manual, because the alternative is a support ticket about a nozzle that has gone cloudy.

After Every Session
Empty the tank. Water left standing is the single biggest cause of smell complaints. On UV models, return the tip to its holder so the sterilisation cycle can run on the part that entered the mouth.
Weekly
Rinse the tank and, on models that have one, the filter screen. LP-221 carries a built-in filter screen and LP-233 has a negative ion water filter built into the tank.

Replace Tips Every Three Months
Set the replacement interval in the manual and sell the spares. Nozzles, cables and mouthguards are orderable as separate line items against your model, which turns maintenance into a repeat revenue line.
Charging Habits That Protect The Cell
Every battery model in this catalogue charges by Type-C. Dry the charging port before plugging in - the bodies are IPX7 but the habit of charging a wet unit is worth designing out of your manual copy.
