Registering your Sirena does two concrete things. First: we keep the serial number, the date and the place of purchase on file, so if you ever need the warranty you won't be hunting for an eight-year-old invoice. Second: we tell you when it's time to rinse or replace the HEPA filter and have the machine serviced — the maintenance that keeps the motor alive and that the warranty conditions require.
You can register it even if you didn't buy it from us. Thousands of Sirenas were sold across Europe through distributors who are no longer around: if yours is one of them, registering it makes us your point of reference for parts and service.
Where to find the serial numbers
- On the main unit: label underneath the body, the same one with the electrical details.
- On the power nozzle: label under the brush, near the wheels.
- If either is unreadable or missing, leave the field empty and say so in the notes: it happens often on older machines.
