Hotpoint Aquarius..Excessive fluff...help!?

I have the Hotpoint Aquarius tumble dryer and although I remove the filter after 1 or 2 cycles to clean the fluff away I have noticed it gathers excessively in the empty bit what the filter slots into. This causes it to gather up onto the square side panels and eventually ends up in the drum, your hand cant fit down without getting it stuck because its too narrow...any ideas into getting the remainder fluff out would be very much appreciated folks!!...:-)
