Rollover with these washers is good if you get the water-to-clothes ratio just right. And if you don't load clothes past the third row of holes down from the top of the tub, rollover is great.
I got tired of jerry-rigging my water level control with a rubber band and a picture hook (which I can hook right under the face of the console, so I usually just load it to match the water level, these days. I suppose it's about an 8-lb. load. max, which gives it the functioning capacity of an early 1950's washer.
Having said that, I washed a very large load of highly-stained kitchen whites last night (and used my hook/rubber band on the water level control). Using liquid Tide With Bleach Alternative, 2 Tide Stain Release pacs and 1 cup of liquid chlorine bleach (during the last 6 minutes of the wash cycle), everything came out perfectly clean. And yes, with that toxic brew, I used the extra rinse option!
But boy HOWDY, they're an easy machine to overload. The manual says to "load clothes to the top of the agitator blades", which on the dual-action agitator is up to the top row of holes in the tub. I tried this once, and watched the clothes get dragged around in circles with no rollover whatsoever. It made me cringe, like when I see a huge load grinding around in an impeller-based top-loader.
Oh, one more thing: When you wash sheets, load it as you would a Unimatic Frigidaire---in quadrants---and tuck the loose ends of the sheets underneath. I put one queen-sized sheet in at 12:00 and one at 6:00; then I put three pillowcases in at 3:00 and another three at 9:00. This pretty much stops the wild tangling that can happen with sheets in these indexing-tub machines.
One big plus for the Frigidaire: It's nearly impossible to cause a cabinet-banging unbalanced load. I regularly wash 1 pair of heavy jeans, and have never had a problem. A front-loader (and some top-loaders) would either stop (and buzz if you grew up with a BD Kenmore), or slam the cabinet around. I've never, ever had a load it couldn't spin. Occasionally, I'll open the lid on the final spin and wonder why the wildly-oscillating tub doesn't just launch out of the machine, but it's spinning quietly at top speed, LOL!
