Zoom on the Powerhorse 750143
In a nutshell, the Powerhorse 750143 is a heavy duty, commercial pressure washer, which not only offers an all-around versatile cleaning experience, but that also allows:
- spot cleaning of hard, unpainted surfaces and high-reach cleaning
- intense cleaning of hard, unpainted surfaces
- cleaning of painted and fragile surfaces
- application of detergent and cleaning solutions
Using an impressive 212 cc (6 hp) engine, its axial cam pump delivers a pressure of up to 3100 PSI (roughly 52 times more than a standard garden hose) and a flow of up to 2.5 GPM (values claimed by the manufacturer). Together, the values result in a cleaning power of 7750 Cleaning Units.
This gas-powered pressure washer’s engine is started by a traditional pull-start mechanism.
Gasoline is stored in a fuel tank with a maximum capacity of 0.95 gallon.
Design & Handling
The Powerhorse 750143 is very mobile, due to its hand truck design and approximate dimensions of D21 x W25.5 x H38.5 in. Its sturdy steel frame provides longevity to the assembly. The foam-padded fixed handle adds to the 750143 convenience of transport, while offering a comfortable grip.
The majority of users will be able to maneuver this unit easily, it only weighs 68 lbs. Its 212 cc engine and steel frame all add up to a substantial part of that weight. But, as the 750143 does have a set of two 10" never-flat wheels, it can be easily maneuvered and manipulated.
