All of the other versions of this machine, with the autofill, are HE impeller machines. I have one of those too, labeled Whirlpool Cabrio though it's not a true Cabrio. The stores around me have had this machine for only a couple of months now. The fill does take longer as it restricts water flow for the spray rinses. To make the machine simpler, Whirlpool put on valves that restrict the flow of water constantly making the fill take a little longer, but not much. The machine does use use the tub break during any of the spin cycles to stop the tub either, it allows the tub to coast to a stop. The lid locks as soon as the machine is started and unlocks at the end of the cycle or when all parts have stopped moving if the machine is paused. (This can take a couple of minutes if the machine was spinning.) Other than that, the machine doesn't really take noticeably longer. Maybe 5-7 minutes longer overall. The machine takes less time than a normal washer if the single spray rinse is used.
Here's a video of the machine doing it's full 700 RPM spin with a proper Whirlpool agitator!
