Description

The Hotsy 900 Series stationary electric hot water pressure washer is built for facilities that need dependable hot water cleaning for daily commercial use. Delivering 4.0 GPM at 2,000–2,300 PSI, the 900 Series is ideal for automotive repair shops, fleet maintenance facilities, manufacturing plants, equipment service bays, and other applications where electric power and consistent hot water performance are essential. Available with natural gas (NG) or liquid propane (LP) heating, it quickly cuts through grease, oil, and stubborn grime while eliminating engine exhaust in indoor environments.

Machine components are easily accessible for maintenance, while the built-in hose reel mount, float tank, and included 50-foot high-pressure hose, trigger gun, and wand help maximize productivity and minimize downtime.

Which Type of Hot Water Pressure Washer Is Best for my Business - Gas or Electric?

Both electric and gas hot water pressure washers deliver professional cleaning results, the difference is where and how you work.
