Jeff....my point is the average person may leave a washcloth by accident in the machine, and then complain that the lint attached to their clothing, and yet wonder why the filter didn't do it's job...
people like you and I know how to wash and sort properly to reduce if not eliminate lint problems...
Overflo rinses were probably the best, filter flo's eith with a pan or brush were also very effective, as well as TRUE magic clean filters with a reversing flush worked well at reducing the amount of lint...
I'm just not convinced of a contraption just sitting there, and water currents from the agitator and clothes is what makes it work and clean itself....
yet we could go on and on...but you have to wonder, and I know and have seen water currents pushed into the outter tub during agitation, I just find that many machines like GE filter flo, and Whirlpool/Kenmore non self clean are more effective by pulling water from the outter tub and returning it to the inner wash basket a true use and function of water being filtered....
TRUE self clean types pull water from the outter tub and return it to the outter tub, just not as effective
and what really gets me, and I know collecting lint from a filter is slimmy, gross, yucking, etc., people who complain about touching the lint....versus...clogs drains, septic, and traps, I think I would rather have to clean a small filter compared to tearing into the drain lines or paying a plummer to fix an issue like this....yet these same people clean the lint trap in the dryer, and how about hair in the bathroom sink, better yet the sludge/hairy/stringy gunk in the tub drain
