New Karcher HDS 1.7/12 U Ed Upright Hot Water Pressure Washer
Our Take (from the SES Sales Team)
“The HDS 1.7/12 U Ed is Kärcher's entry-level upright hot water pressure washer, aimed at tradesmen, maintenance crews and contract cleaners who want hot water but only have an ordinary 120 V outlet. An electric motor runs the pump and a fuel-oil or diesel burner heats the water to 176°F, which cuts grease and oil far more easily than cold water at the same pressure.
The upright layout is the selling point. It stands on a 24.3 x 24.3 in footprint, has large wheels and a tilting aid for steps and rough ground, and the pump and fuel tank are spill-proof so it can lie down in a small service van. Controls are simple, with off, cold and hot settings, and it comes with the EASY!Force trigger gun, a 33 ft hose and a 33 in lance.
The trade-off is output. At 1.7 gpm and 1,200 psi it suits light commercial work such as equipment, entryways, dumpster pads and small vehicles, not daily fleet washing. If the machine will run for hours every day, look at a larger HDS class model.”
