The whole idea behind the BD DA was to wash a larger load and have turnover....the original concept and test was a packed test machine, with a clear tub, adding a black sock to a white load, and watch the actual turnover from the top of the washer to the bottom where the cleaning was actually taking place....only Kenmore had it, and designed it first, mainly because every agitator by them had only vanes at the bottom, if you wanted vigorous wash action on a REAL load (not a few pieces of clothing in a large tub of water) you had to wash HALF loads, at least Whirlpool gave you VANES up to the top, even if the machine was a EX-LARGE capacity, the vanes stretched with it, on a Kenmore or even a Maytag, they only increased the length of the agitator post....
That's why on almost every YOUTUBE video, they either wash a small load to show wash action or they fill the tub all the way up and add a few pieces to show "great" rollover...
I know some of you people out there only have yourselves to wash for, and can't wait for a few pieces to build up, just to get your machine running, and theres others out there who have many members in a household, some with only one set of machines, and do you really think your gonna wash a few pieces at a time or get a whole load done, I love watching the machines operate as the next member, but theres days I have a million things to do, I have laundry EVERYDAY, and I have 3 sets hooked up, all going at the same time to keep up...
Unimatics of any type are fun to watch, and so are Maytags and countless others, we have a ball with them, but if you had to wash several loads a day and juggle everything else in daily lives, some may consider a better perspective of getting a job done faster.....thats what the "average" public was looking for when the DA was introduced...
just my opinion...
