Pros
  • 3 gallon tank keeps it pumping far longer between fill-ups than most 2 in pumps
  • Comes with hoses and a wheel kit, so it is ready to work out of the box
  • Passes 1/2 in solids for muddy or sandy water
Cons
  • At 79 lb with the wheel kit it is heavy to lift into a truck
  • Two-year warranty is shorter than Generac’s three
