You're wrong on the "no venturi action"!  The Automatic Aquarium Water
Changer actually works on the venturi principal and removes the same
amount of water that it puts in the aquarium.  It will pump "uphill", but
it is not recommended for safety (if the venturi should get clogged, you 
would then have the possibility of an overflow).  Actually, that is why
the company put an inline filter on the unit so that the venturi remains
clean and protected.

Both pieces of equipment are good, but they are for different purposes.
You can enjoy your aquarium while water is being changed with the
Automatic Aquarium Water Changer.

Best wishes for the coming Holiday Season.
