Baracuda G3 vs G4

Jun 10, 2007
A friend recommended the Baracuda G3 as a pretty good pool cleaner. I saw that there is a G4 model also. Is the extra $$ worth it to get the G4, instead of the G3. Thanks for any input.

All thats different about the g4 is the design. The front acts like a sail propelling it through the water batter. Other than that their the same.
