As many of you know, we use the Turbo Twister modified to clean parking garages. However, we have tested two side by side non motorized surface cleaners. The one was Hydro Tek ANT 28, with the other being the Steel Eagle 30 inch.
We found that the Steel Eagle cleaned faster and more aggressively than the Hydro Tek. This could be because of the swivel. The Steel Eagle was fitted with the optional Dueblin swivel with a 3 arm wand ( Nozzle size (3) 2.0 @15), where the ANT 28 had a different swivel with a 2 nozzle arm( Nozzle size (2) 3.0 @ 15).
Both surface cleaners were run at 5.8 GPM , 4300 PSI with 225 degrees, though both manufactures claim their units can do more GPM's and more heat, up to 250 degree's. We noticed that the Steel Eagle spun faster than the Hydro Tek, however, this could of been because of the extra arm and /or because of the different swivel used.
With that said, we bought the 30" Steel Eagle with the Dueblin swivel, 3 arm, for just over $800 with free shipping.
We wanted to test the Big Guy, but no vender's in our area had one to test.
