I'm not clear on your reference to funny agitator. Do you mean the EcoSmart agitator toploaders?
AquaSmart has fully variable water level, not limited to 5 levels like the EcoSmart. Basket float is the primary factor for HE fill level, but there's also a minimum level. Basket float level is a factor in the calcuation for agitation speed.
Most cycles that can run on deep fill (non-HE mode) run some agitation at HE level to check motor load resistance for calculating the deep fill level. The various Bulky cycles fill higher by default.
Sheets cycle is kinda odd in that it fills to a fixed non-HE level, agitates a bit, then drains some water, apparently to attain appropriate impeller contact. Runs three repeating agitation actions, aim is to avoid tangling. Two sets of sheets washes better than one set IMO.
There are several AquaSmart videos on my YouTube. Wash action is quite good IMO, better than the lethargic action of many newer HE impeller machines, and the wash period isn't as long (12 to 15 mins is typical). Rinsing takes up most of the cycle time.
I sent documents with a bunch of technical design detail about both AquaSmart and AeroSmart to the email addy on your AW profile. Some of it may be F&P marketing propaganda.
