Design & Handling
Thanks to its hand truck design and approximate dimensions of D23.5 x W18.5 x H35.4 in, the Sun Joe SPX4500 offers great mobility. The robust metal frame guarantees longevity of the assembly. The foam-padded fixed handle adds to the SPX4500 convenience of transport, while offering a comfortable grip.
The unit can be very easily carried around, as it weighs just 37 lbs. On top of its light weight, the transportability and easy of use of this model is further improved by the addition of two 9.4" wheels.
The Sun Joe SPX4500 comes with a spray gun, a wand, a pressure hose, 5 nozzles and a detergent injection feature, which are detailed below.

The Sun Joe SPX4500'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 SPX4500 compare to similarly priced pressure washers.
- With its 2000 PSI max pressure output, the Sun Joe SPX4500 is in the expected pressure range, for electric units in the $200-250 price range. If your priority is the highest possible power of the water stream, in this price range, we suggest checking out the Ryobi RY142300, which reaches up to 2300 PSI.
- This washer, with a GPM of 1.1 (gallons per minute) has a somewhat lower water flows value compared to devices in its price range. If you’re after the highest rinsing efficiency, one of the units with the highest water flow in the current price range is the Powerhorse 157055, that can deliver up to 1.5 GPM.
- The SPX4500 has 2200 Cleaning Units (PSI x GPM), which is considered low in comparison to other electric devices of this price. If the highest overall cleaning power is your top priority, the Kärcher K5 Premium, which can reach up to 2800 Cleaning Units, is one of the most efficient of the devices in the current price range.
As you can see from this interactive chart, when compared to other electric washers between 2000 and 2500 Cleaning Units, the Sun Joe SPX4500 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.
