Our tumble drier has just broken so need to get a new one
This one is about 24 years old so it has done a very good job 
The fluffy collects in the main door in a plastic grill thingy (over the window) that is very easy to unclip, take out and open then take out the fluffy
It seems by looking online this afternoon that the plastic grill thingy that fits on the window/door has gone in the "new and improved" tumble driers
The thing that is good about the fluffy being collected on the door grill is that you can see how full it is each time you open the door
I also seem to remember that these fires were "maybe" caused by the fluffy close to the heating elements so am nervous what tumble drier to get that will be safe.
The size is important cos we need it to be 59.5 wide and 84.5 high which reduces the number of ones available with a back vent for a tube/pipe thingy
TIA MN for any help
