Filters first, wash them all and you will be surprised. Also, what about the
brushes and the commutator, these can wear to the point that the arcing
melts the metal or underlying plastic and the motor, to use a technical term
is knackered. Also of cours as I discovered with a Vax, it seems some motors
are just not very good for very long.

Also check the obvious the flexible tube attached to his nose.

This can become partially blocked especially when clearing up DIY
rubbish and reduce the airflow into the internals and cooling air to the
motor.

Possibly compare the suction at Henry's nose with the tube removed and
then again with the tube fitted.

I've found that sometimes the only way to clear the blockage in the
flexible hose is to use a garden hose and fill the tube with water and
then quickly release all the water. Repeat so the water flows both ways.
