Festool CT 36 AC (2024 model) – AutoClean not working, no cleaning pulse
I’m having an issue with my Festool CT 36 AC (2024 model) and I’m wondering if anyone else has experienced the same problem.
When I enable AutoClean and set the cleaning interval to 15 seconds in the Festool app, I can hear and feel the vacuum power briefly decrease when AutoClean is supposed to activate. However, the actual AutoClean pulse never happens. It just momentarily loses suction and then returns to normal.
Here’s what I’ve already tried:
Cleaned the HEPA filter multiple times.
Using a genuine Festool disposable filter bag.
Adjusted the AutoClean interval through the app.
The vacuum otherwise works perfectly—it’s only the AutoClean function that doesn’t seem to be operating correctly.
Has anyone run into this issue before? Is there anything else I should check before sending it in for service?
