I seem to have a very strange fault with this cleaner.
The cleaner started pulsing so the pre filter was cleaned.
A few weeks later the battery died and was replaced,
on reassembly it started pulsing again.
This time the unit was stripped down and the cyclone
was found to be filthy and was thoroughly cleaned.
the pre filter was renewed and the motor filter cleaned.
after careful reassembly the problem persists!
the cleaner will work/run if you lift up / remove
the round pre filter,as soon as you let it go
the suction seals it and the motor pulses again.
I cannot understand how/why the filter is
stifling the airflow?
I am tempted to drill several holes in the
top of the filter body to let the air into
I have tried removing the filter fabric and
putting just the filter body back but
that does not work either.
Any thoughts please
