Power

The Simpson ALH3225-S in use

The Simpson ALH3225-S

With a 196 cc (6.5 hp) engine, its triplex pump delivers a pressure of 3200 PSI (roughly 53 times more than a standard garden hose) and a flow of up to 2.5 GPM (CETA-certified values), resulting in the Simpson ALH3225-S's cleaning power of 8000 Cleaning Units.

This gas-powered pressure washer’s KOHLER SH265 engine is started by a traditional pull-start mechanism.

The fuel is stored in a steel tank, which can hold up to 0.95 gallon of gasoline.

Design & Handling

The wheelbarrow design of the Simpson ALH3225-S grants mobility and stability to the unit. The aluminum frame ensures the device's durability, as it will not rust. The handle adds to the ALH3225-S convenience of transport.

The majority of users will be able to maneuver this unit easily, it only weighs 74 lbs. As its 196 cc KOHLER SH265 engine and triplex pump account for a good portion of that weight, Simpson's choice of an aluminum frame allows the device to stay at a reasonable weight. However, the two 10" pneumatic wheels allow the ALH3225-S to be easily manipulated and maneuvered.

Main Features

The Simpson ALH3225-S in use

The Simpson ALH3225-S

The Simpson ALH3225-S's package includes a spray gun, a wand, a pressure hose, 5 nozzles and a detergent injection feature, with a more detailed description below.

  • Soap injection: While the device doesn't feature a soap tank, detergent supply is ensured by a siphon hose. The detergent is diluted with a 7:1 ratio by the Simpson ALH3225-S's automatic soap dilution mechanism. The detergent is automatically added to the water when a soap nozzle is connected.
  • Pressure hose: The 35 ft ⌀5/16" high-pressure hose, which is included with the device, can be stored neatly on the unit itself when idle, using a set of convenient hooks.
  • Spray gun and wand: The included classic ergonomic spray gun and its steel wand can be easily stored in a side hook.
  • Nozzles: The table below shows you the 5 included nozzles, as well as the surfaces they're the most appropriate for.

The Simpson ALH3225-S's performance versus other pressure washers

The following charts are provided to give you an idea of how the key specs of the Simpson ALH3225-S compare to similarly priced pressure washers.

  • With a maximum pressure output of 3200 PSI, the Simpson ALH3225-S finds itself in the expected pressure range among gas-powered units that cost between $400 and $625. If you're going after the highest possible power of the water stream, one of the best in this price range is the DeWalt DXPW3625 that can reach up to 3600 PSI.
  • As this washer can produce a flow of water of 2.5 GPM (gallons per minute), it is average in terms of water volume for the above-mentioned price range. If being able to rinse away debris as efficiently as possible is your priority, one of the products with the highest GPM in this price range is the Lifan LFQ3370, with 3 GPM.
  • The 8000 Cleaning Units (PSI x GPM), of the ALH3225-S result in an average cleaning efficiency, compared to similarly priced gas-powered units. If you consider the highest overall cleaning power as a really important factor, the Lifan LFQ3370 and its 9900 Cleaning Units has one of the highest cleaning efficiency of all the similarly priced units.

Price comparison

As you can see from this interactive chart, when compared to other gas-powered washers between 8000 and 8500 Cleaning Units, the Simpson ALH3225-S is on the average side of the price range.

Therefore, this pressure washer nicely fits in the expected budget for this kind of cleaning power.
