I've long heard this mantra that front load washers are more effective
at cleaning than a top loader.

I used front load Speed Queens at the local laundry for months. I
can't say I noticed any obvious evidence that it got the clothes any
cleaner. Seat of the pants, it doesn't make sense that it would. In a
front loader, the clothes are being plopped into the soapy water over
and over. In a top loader, the agitation action seems to be a more
active approach. Now that I've got a top load washer again, it seems
the clothes are at least as clean as they got in the commercial front
loader.

Have there been any actual studies made?
