Description

Tackle your toughest home, outdoor and auto cleaning tasks with the powerful 13-amp induction motor, designed to last longer, run quieter, and work cooler than traditional universal motors. (source: Sun Joe (opens in a new tab))
Note: Sun Joe claims that this unit provides 2500 PSI and 1.48 GPM. In fact, the stated PSI value is only at the initial trigger pull, while the stated GPM value is with a nozzle opened to the lowest pressure. Under a typical load, the working pressure is 2000 PSI and the flow is 1.1 GPM.

Zoom on the Sun Joe SPX4501

The Sun Joe SPX4501 is a medium duty pressure washer, that provides its users with an all-around versatile cleaning experience, and enables:

  • spot cleaning of hard, paint-free surfaces and out-of-reach areas
  • intense cleaning of tough, paintless surfaces
  • cleaning of painted and fragile surfaces
  • application of detergent and cleaning solutions

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 13 amp motor, its axial pump can deliver a pressure of 2000 PSI (around 33 times more than a standard garden hose) and a flow of up to 1.1 GPM. Combined, these values mean that the Sun Joe SPX4501 has a cleaning power of 2200 Cleaning Units.

Since it is an electric pressure washer, the motor of the SPX4501 is started simply by an ON/OFF switch. The unit is ready-to-use with peace of mind, thanks to the included 35 ft GFCI cord.

Design & Handling

Thanks to its hand truck design and approximate dimensions of D23.5 x W18.5 x H35.4 in, the Sun Joe SPX4501 offers great mobility. The foam-padded fixed handle adds to the SPX4501 convenience of transport, while offering a comfortable grip.

With a weight of only 45.9 lbs, the unit is definitely easy to carry around. As if this lightweight wasn't enough, the device also features two 9.5" wheels to further improve its ease of use and of transport.

Main Features

Along with the Sun Joe SPX4501 itself, the package also includes a spray gun, a wand, a pressure hose, 5 nozzles and a detergent injection feature, which are discussed in further detail below.

  • Soap injection: Detergent storage is ensured by a removable 1 gal tank. The detergent dilution ratio can be manually selected, using a dial. The detergent will be added automatically to the water when a soap nozzle is attached.
  • Pressure hose: The 20 ft high-pressure hose, which is included with the device, can be stored neatly on the unit itself when idle, using a convenient hose reel, which also improves its lifespan.
  • Spray gun and wand: A side hook allows for an easy storage of the included classic ergonomic spray gun and its wand.
  • Nozzles: The following table illustrates the 5 included nozzles, along with the surfaces which they are the most suitable for.

Other Features

  • Onboard storage: Stay prepared for any job with Sun Joe SPX4501's handy storage area, which allows you to neatly store any nozzles and accessories which you may need for the job.
  • Safety: Safety of operation is enhanced by a trigger lock mechanism (which prevents accidental operation).
  • Accessories: The Sun Joe SPX4501 comes with an owner's manual (opens in a new tab) and some basic documentation to get you quickly started. On top of that, you also get nozzle cleaner, pressure hose, wand, spray gun and power cord.

The Sun Joe SPX4501's performance versus other pressure washers

The following charts are provided to give you an idea of how the key specs of the Sun Joe SPX4501 compare to similarly priced pressure washers.

  • With its 2000 PSI max pressure output, the Sun Joe SPX4501 is in the expected pressure range, for electric units in the $220-330 price range. If you're going after the highest possible power of the water stream, one of the best in this price range is the Sun Joe SPX4601 that can reach up to 2300 PSI.
  • In the aforementioned price range, this washer, with 1.1 GPM (gallons per minute), is placed on the lower end of the GPM scale. If rinsing away debris most efficiently is your priority, one of the devices with the highest GPM in this price range is the Sun Joe SPX9004-PRO, which can reach up to 1.8 GPM.
  • The SPX4501's Cleaning Units, 2200 CU (PSI x GPM), fall into the lower end when compared to electric devices of similar price. If you are after the highest overall cleaning power, the Kärcher K5 Premium with its 2800 Cleaning Units is one of the products that can achieve the highest cleaning efficiency in this price range.

Price comparison

As you can see from this interactive chart, when compared to other electric washers between 2000 and 2500 Cleaning Units, the Sun Joe SPX4501 is on the expensive side of the price range.

While certainly not the cheapest of its cleaning power range, purchasing it could most likely also mean enjoying the reliability of a high-end product.
