Does double cyclone use G-max (Emax) flush

Trying to determine which new toilet to get.

Looking at the Drake & Ultramax

Came across the Drake II and Ultramax II with 1.28 gal flush.

Apparently these werre the Gwyneth 2 and 1 piece toilets respectively.

Trying to decide between Ultramax and Ultramax II and Drake & Drake II
to replace two toilets - one one piece and one 2 piece

Is the flushing system for the double cyclone like the GMax with just a change to the bowl?

Any comments or suggestions would be appreciated.

Thanks

Yes it does the difference in the Double Cyclone is the way the water gets into the bowl.
The Drake and Ultramax has some rim was but flushes more like a waterfall.
The Double Cyclone water comes out of two holes and has no rim holes.

For what it's worth, I have 2 one-piece Gwyneths and would definitely buy them again if I needed another toilet. I like the double cyclone bowl wash, and they flush extremely well.

thanks

Thanks Peanut9199 and Steve W

I am pretty certain I will go with the ultramax II for one of the toilets and maybe a drake for the other.

Just concerned about the 1.28 gal flush a bit.
