Question: I really need to pull the trigger on something, and probably get at 2 or three machines.
If 85% of our jobs are carpet/upholstery, would you recommend getting the 1500, or just using a water otter when needed? My techs have said that they cannot drive a spinner with the otter - I need to investigate.
When using the 1500 at lower psi, can the system function off of 1x15A and 1x20A cord?
What is the CFM and lift comparison between the 500 and 1500 models?
Thanks again for your help

The all in one tile cleaning machines are heavy and always offer less vacuum than a 500 psi carpet cleaning machine. I personally like lots of vacuum. This also means you would have to carry some type of pressure washing pump with you to use for tile cleaning work.
Goliath 500 psi models are a 30 amp vacuum.
170" X 250 cfm = 42,500 vacuum units
Goliath 1500 is a 17.4 amp vacuum
117.4" X 198 cfm = 23,245 vacuum units.
Goliath 500 is a 33 gallon pump out for true water extraction flood work.
Goliath 1500 is a 3.3 gallon pump out
Goliath 500 psi uses a .72 gpm = 360 cleaning speed
Goliath 1500 psi X 2.1 gpm = 3150 cleaning speed
Water Otter is 1200 psi X 2 gpm = 2400 cleaning speed and usually works for 12" spinners and smaller.

Answer: The Goliath 1500 is a balanced electrical machine. Both the pumps run off of both power cords. Each cord runs exactly 1/2 the machine.
The water pressure dictates the amp draw required. 3150 cleaning unit pump draws 18 amps be divided by two cords = 9 amps per cord.
Pumps in half the amp draw to start and the balance is issued between 0 psi and the the max pressure. So in this case the pump needs 9 amps to start (4.5 amps per cord) and the remaining 9 amps is pulled to push the 1500 psi or .6 amps for each 100 psi you ask it to push. In other words 1000 psi is 9 to start and then 6 amp to run = 16 amps. Again we divide by 2 because each power cord supplies half the power. The 17.4 amp vacuum system is also about 8.7 amps per cord. The pump out pump 0.7 amps per cord. So lets look at the Goliath 1500 being used at 500 psi. Total amp draw is 12 for the pressure pump, 17.4 for the vacuum, 1.4 for the pump out = 30.8
Divided by 2 cords = 15.4 amps per cord.
Now at full pressure: water pressure 18 amps, vacuum 17.4, pump out 1.4 = 36.8 amps
Divided by 2 = 18.4 amps per cord.
