Hello MVacs,

Thanks for your reply.

Yes, I have tried different working dust bins so the problem is somewhere in the main body.

This is Brooke’s Vacuums in Brooklyn, New York.



We visited last month while nearby in New York. They are the oldest vacuum store in Brooklyn, they were the first Dyson dealer in the US, and of course, nowadays they are Sebo dealers too. We had a good chat about all things vacuums with the owner and swapped a few ideas.

Its great to go down a rabbit hole online sometimes isn't it? 

Have you tested continuity in the bin?

I just asked our engineer and showed him your video and photos.

He feels the top bearing is shot and the commutator *might* be OK. That would account for some of the noise there, and certainly the sparking. However, without replacing the top bearing and bench testing it, there is no other way to know if the commutator is too far gone or not. Only when the bearing is fixed and the armature runs true will you know if the sparking subsides.
