Trying to fix possible Hoover Vacuum Cleaner

[callevaerudite]

Hi All,
I recently picked this vacuum cleaner up from a charity shop.
I presume it's a hoover from the circular badge but other than I'm not sure what make or model it is!!
I also have encountered an issue with it. I tested the vacuum cleaner for 2 mins and then it just cut out!! I've had a poke around and noticed this 'device' (I'm not sure what the correct name is for it) was cracked. Could this be the possible issue?
Any help with the issue or what model would be appreciated

It is a Hoover Junior but not sure what model exactly, never seen it in that color before.

That looks like the Suppressor so chances are that is the cause of the problem with it.
