well the plastic Profile machines were just cheaper to build, and thats all that matters to a company......
makes you wonder though...many TL machines todays could and still do have a filterflo of sorts....
some of the little portable TLers like Avanti have a filterflo, going thru a stocking screen...
and if they put thought to it, the Calypso with its waterfall could have had a filter pan under the waterfall to filter the recirculating water.....of course what makes the filterflo really function is the moving pan, a stationary screen is not quite the same...
same goes for the Cabrios series, with the powerwash spray, it recirculates water over the load......
the big issue for people in general, they want it there, just out of sight, and so they don't have to clean it!....yet they will clean a dryer filter!....
but in the long run, I think its more for our benefit, the drama, and a gimmick, yes, it does trap lint, but how mny times I hve let it out, and didn't notice a difference...as long as your sorting properly, watertemps and detergent, and cycles....everything comes out fine..
