Zoom on the Sun Joe SPX4600
The Sun Joe SPX4600 is a heavy duty pressure washer, that provides its users with an all-around versatile cleaning experience, and enables:
- spot cleaning of hard, unpainted surfaces, reaching high areas, and removing stubborn stains
- comprehensive cleaning of hard surfaces, vehicle washing, and readying surfaces for painting
- gentle cleaning of delicate surfaces, and low pressure cleaning of larger areas
- using cleaning solutions, and rinsing surfaces to remove residue
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 14.5-amp induction motor, its axial pump can generate a forceful pressure of 3000 PSI (roughly 50 times that of a standard garden hose) and a flow rate of up to 1.3 GPM. While these PSI and GPM values represent the maximum capabilities of the washer under specific conditions, it's important to note that under typical usage, the working pressure is 2300 PSI and the flow rate is 1.1 GPM. When these values are taken together, they yield a cleaning power of 2530 Cleaning Units.
The SPX4600 easily starts up with the press of an ON/OFF switch, providing seamless operation. The unit is ready-to-use with peace of mind, thanks to the included 35 ft GFCI cord.
Design & Handling
Enhanced mobility is a key feature of the Sun Joe SPX4600, thanks to its hand truck design. Guaranteeing longevity, the robust metal frame offers stability and protects internal components, even when subjected to demanding tasks. The foam-padded fixed handle adds to the SPX4600 convenience of transport, while offering a comfortable grip.
With a weight of 36.6 lbs, this unit is designed for ease of maneuverability, catering to a wide range of users. This substantial weight can be partially attributed to the incorporation of the motor and a resilient metal frame. Still, the SPX4600's two 9.4" wheels ensure easy handling and maneuverability.
Main Features
The Sun Joe SPX4600 comes with a spray gun, a wand, a pressure hose, 5 nozzles and a detergent injection feature, which are detailed below.
- Soap injection: Detergent storage is ensured by a 1 gal tank. The device has a dial which allows you to manually select the detergent dilution ratio. Connection of a soap nozzle triggers the pressure washer to automatically incorporate the detergent into the water stream.
- Pressure hose: When not in use, the unit allows for tidy storage of the included 20 ft ⌀1/4" high-pressure hose using a set of convenient hooks, ensuring convenient organization.
- Spray gun and wand: A side hook allows for an easy storage of the included classic ergonomic spray gun and its wand.
- Nozzles: Review the table below to learn about the 5 included nozzles and the surfaces they're recommended for.

- Safety: Safety of operation is enhanced by a trigger lock mechanism (which prevents accidental operation).
