Description
Zoom on the Pressure-Pro PP4240H
The Pressure-Pro PP4240H is a heavy duty, commercial pressure washer, that provides its users with an all-around versatile cleaning experience, and enables:
- complete cleaning of hard surfaces, vehicle washing, and surface prep for painting
- gentle cleaning of delicate surfaces, and low pressure cleaning of larger areas
- applying detergents or chemicals, and rinsing surfaces afterward
The following sections will present you in detail its power characteristics and design, its main features and all the additional features it has to offer.
Power
Powered by a powerful 389cc (13 hp) engine, its triplex pump can deliver a pressure of 4200 PSI (around 70 times more than a standard garden hose) and a flow of up to 4 GPM (values claimed by the manufacturer). With these values combined, the Pressure-Pro PP4240H boasts a cleaning power of 16800 Cleaning Units.
Initiating the Honda GX390 engine of this gas pressure washer is achieved through a classic pull-start process.
The pressure washer's steel tank has a maximum capacity of 0.3 gallon for storing gasoline.
Design & Handling
The Pressure-Pro PP4240H's mobility is greatly enhanced by its hand truck design. Built to endure, the steel frame ensures the assembly's longevity by providing stability and safeguarding internal components under all working conditions. The reversible handle offers further versatility, as its different positions make the unit less bulky when stored.
Tipping the scales at 115 lbs, this unit's weight presents a notable challenge for users, especially when it comes to lifting and moving it, particularly over uneven ground. The main contributors to its weight are its 389cc Honda GX390 engine, the triplex pump and steel frame. Nevertheless, with its two 10" never-flat wheels, users can manage the PP4240H with less difficulty, even over uneven terrain.
Main Features
The Pressure-Pro PP4240H comes with a spray gun, a wand, a pressure hose, 4 nozzles and a detergent injection feature, which are detailed below.
- Soap injection: Though lacking a dedicated soap tank, the device ensures detergent supply via a siphon hose. Upon attaching a soap nozzle, the pressure washer seamlessly integrates the detergent into the water flow.
- Pressure hose: For easy organization, the included 50 ft ⌀3/8" high-pressure hose can be stored on the unit using a set of convenient hooks when it's not in use, ensuring a clutter-free workspace.
- Spray gun and wand: The included classic ergonomic spray gun and its wand can be easily stored in a side hook.
- Nozzles: Review the table below to learn about the 4 included nozzles and the surfaces they're recommended for.
15° | 25° | 40° | Soap | |

- Accessories: Besides the usual owner's manual (opens in a new tab) and documentation to get you promptly started, the Pressure-Pro PP4240H comes with spray gun, wand, soap hose, pressure hose and oil.
