Been looking at the Shazaam: Goliath Quad Vac - 4/2Vacs - 500 psi recently.
Nice machine but think the Jag looks little bit better spec wise, also I prefer the name

what i find interesting is that the jag says it has 298 cfm and the Shazaam Goliath says 200 cfm, the jag says 263 water lift whereas the Shazaam Goliath 170 water lift, yet the Shazaam Goliath claims this machine offers the ability to clean 200 ft from the machine with
full productivity whereas the jag with apparent better spec suction wise, says you can clean at 100',....and beyond (150') even without our exclusive Power Booster System capable of cleaning even further with ease. Someones telling porkies!!
Must admit though I do like both machines but there is a big difference in price probably cos one is 120 volts whereas the other is 220-240 volts.
Dont quite know if the jag is autofill though, because I think what they are saying with the Goliath is that because you have constant feed of pressure to the pump maintains more pressure, never knew that.
