Description

The Hotsy 800 Series pressure washer is built for commercial cleaning jobs that need hot water power in a portable package. The lineup covers 4.0 to 5.0 GPM and 2,000 to 3,000 PSI, with multiple voltage and phase options so you can match the machine to the electrical service available at your shop or facility.

The featured Model 821 delivers 4.0 GPM at 2,300 PSI using a 6.2 HP electric motor and Hotsy belt-drive triplex pump. Water is heated by an oil-fired upright burner rated at 381,000 BTU/hr. Hotsy also equips the 821 with an integrated float tank, adjustable thermostat, upstream detergent injection, 8-gallon fuel tank, 50-foot high-pressure hose, and a cabinet narrow enough to fit through a standard doorway.

With solid rubber tires, casters, and forklift slots, this portable electric hot water pressure washer is set up for facilities that need serious cleaning power without committing to a stationary installation.

Hot Water Pressure Washer FAQs

What Commercial Hot Water Pressure Washer Should I Choose?

Proven brands are important for reliability and serviceability. At Seattle Pump & Equipment Co. we carry Hotsy, BE, and AaLadin brand hot-water pressure washers in gas, diesel, and electric powered models built for demanding commercial and industrial cleaning. Our team will help evaluate job-site conditions and match you with the model that fits your PSI/GPM, power-supply, mobility, temperature, and budget requirements.

Yes — Seattle Pump offers short-term and long-term rentals of hot water pressure washers (including portable and trailer-mounted units) so you can access industrial-grade cleaning power without full purchase. Lease-to-own programs are available as well.

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.
