Hello Tech Michael,
Seals at both ends appear to be sound and there are no cracks.
There is no obvious build up of any debris. The suction is going into the Hepa filter but is not transferring to either floor or side hand pipe. Pipe is clear.
I think it is about 4 years old. There is a fair amount of air coming out of the grill on the front below the cyclone chamber. Is this normal?
I am not sure what I did but a short time ago the cyclone effect started working but has now stopped again.
