Description

Built tough enough to handle the strenuous needs of commercial use, the powerful Simpson Cleaning ALH4240 4,200 PSI 4.0 GPM 389cc Gas Pressure Power Washer can also easily handle any home project on your to-do list. A reliable motor from Honda and a triplex pump from CAT grace this cleaning tool, giving you the peace of mind that you're purchasing a pressure washer constructed with components from 2 of the most reliable and well-known brands in the world. Keeping its construction strong but lightweight was no easy task, but this 128-pound power washer was made using an aircraft-grade aluminum frame so you know it's built to last. It's great for construction jobs, outdoor cleanup, equipment cleaning, car/RV washes, decks, sidewalks, driveways, and more. An included 50-foot hose means you can restore your home or office to its former glory by blasting away dirt and grime anywhere it's hiding. As an added bonus, the hose is kink and abrasion resistant so you can wash longer without stopping to untangle. Dual pneumatic 13-inch wheels are great for uneven terrain, allowing you to wheel this washer to wherever the mess is. And because this is a gas model, you have the ability to be mobile at all times, with no need for an electrical outlet. 5 included quick-connect nozzles give you plenty of versatility, allowing for angles of 0, 15, 25, and 40 degrees, plus a soap nozzle. Tackle any job, big or small, with the power of a commercial power washer like the Simpson Cleaning ALH4240 4,200 PSI 4.0 GPM 389cc Gas Pressure Power Washer.

Awesome Pressure Washer

I needed a tough dependable pressure washer for my business. This one's it. I knew from the concern they gave in shipping it matters about their machine. Excellent quality, easy operation. I am impressed.

What a Powerhouse!

4,200 psi = all the pressure I'll ever need, even for resistant driveways stains. 4.0 gpm = cuts work time nearly in half. Aluminum body keeps weight down and suits my coastal environment. This is a mean-business machine! Couldn't be happier.
