New ALH 4240 pressure washer

I’m a landscaping contractor. I’ve owned about 5 lesser powered/specked units over the years including three $400-600 Simpson units. I finally decided to go big or go home because time is money. This unit is as advertised. Quality all the way. Tons of power/pressure. You get what you pay for jumping up to this size/class unit. The price from Factory Pure was very fair based on searches and delivery was excellent. Wait time in total was maybe two weeks. No regrets.

Great machine. Plenty of power. The Honda motor is a must. The aluminum frame is nice so that nothing can rust and helps cut weight. I do wish it had an easy start feature on the pump, but I still love it. Factory pure was very professional and responded quickly to any questions I had. The free shipping to the carrier terminal was a great option to save some money.
