Rinsing
Yes, this EASY looks very BOL, many other models had faucets and the shower cone in the spinner.
Rinsing in most twin tubs is not a "one time" process. You fill the spin tub with soapy clothes and spin that out, then fill with clean water and spin it out, then re-distribute the clothes around and fill clean water and rinse again. The spintub doesn't need much water, it's still efficient to fill and spin maybe 3 times before you'd use as much water as a complete wash tub fill on an automatic. It's very "hands on" but also fun and effective.
The models with the cone are better for sure, and the faucets to let you hose the soap back into the washtub and easily refill the spin tub wth fresh water. This model likely just drained out to the floor drain on both sides, and used a garden hose to fill. BOL is BOL. Did EASY BOL mean no pump at all, maybe?
Hoover Twin Tubs---I redistibute the clothes at least twice for very good rinsing. And if you want fabric softener, I have a large bucket of water with a capful of FS. For the last rinse, I puor the bucket over the clothes instead of the fresh clean water, it works well.
In comparison, have you ever checked a load of clothes in an automatic after the first spin and spray, moments before the rinse fill? In my Kenmore and Maytag, not so much GE, the bottom bunch of clothes in a large load, pressed against the perf tub, can still have a lot of hot water heat in them, meaning still a lot of suds after extraction and spray. In my 1-18 with the circle spray excellence, I only notice if it's all towels or jeans, very heavy material.
So if automatics(most of them) do Extract-Spray-Deep Rinse-Extract-Spray again(some) you really can't complain if a twin tub spinner requires a redistribution for a second rinse. And both EASY and HOOVER literature talks about the option of deep-rinsing with fresh water in the agitation tub. They are quite versatile, and ENTIRELY hands on.
All this talk makes me want to pull my EASY and HOOVER out for a washday, but with all the "hands in water" required, I'll wait until summer.
