Description

Crafted of aircraft grade aluminum, making it lighter in weight than most steel frame pressure washer designs. Perfect for contractors who specialize in deck cleaning, wood restoration, paint preparation, graffiti removal and all other professional cleaning services.

Zoom on the Simpson ALH3225-S

The Simpson ALH3225-S is a heavy duty, commercial pressure washer, that provides its users with an all-around versatile cleaning experience, and enables:

  • spot cleaning of hard, paintless surfaces and reaching far-away areas
  • intense cleaning of hard, unpainted surfaces
  • cleaning of painted and fragile surfaces
  • application of detergent and cleaning solutions

Its power characteristics and design, its main features and all its additional features are presented ahead.

Power

The Simpson ALH3225-S in use

The Simpson ALH3225-S

Its triplex pump, which utilizes a 196 cc (6.5 hp) engine, may deliver a pressure of up to 3200 PSI (almost 53 times more than a standard garden hose) and a flow of up to 2.5 GPM. These values correspond to a cleaning power of 8000 Cleaning Units.

A classic pull-start mechanism is responsible for starting the gas-powered pressure washer’s KOHLER SH265 engine.

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 allows the device to remain highly durable, as it will not rust. The handle adds to the ALH3225-S convenience of transport.

The device can be maneuvered with ease by most, since it only weighs 74 lbs. Since the 196 cc KOHLER SH265 engine and triplex pump account for a large part of its weight, Simpson's utilization of an aluminum frame keeps the unit at a reasonable weight. But, as the ALH3225-S does have a set of two 10" pneumatic wheels, it can be easily maneuvered and manipulated.

Main Features

The Simpson ALH3225-S in use

The Simpson ALH3225-S

The Simpson ALH3225-S comes with a spray gun, a wand, a pressure hose, 5 nozzles and a detergent injection feature, which are detailed below.

  • Soap injection: Even though the device doesn't have a soap tank, detergent is supplied by a siphon hose. The Simpson ALH3225-S features an automatic soap dilution mechanism, that will dilute your detergent with a 7:1 ratio. The detergent is automatically added to the water when a soap nozzle is connected.
  • Pressure hose: The included 35 ft ⌀5/16" high-pressure hose can be neatly stored on the unit when idle thanks to 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 following table illustrates the 5 included nozzles, along with the surfaces which they are the most suitable 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.

  • The Simpson ALH3225-S and its 3200 PSI, ranks amongst gas-powered pressure washers with a comparably low pressure output, considering the units that cost between $500 and $600. In case you are looking for a device with the highest possible power of its water stream, one of the top achievers in this price range is the A-iPower APW4200 with a PSI of 4200.
  • In the aforementioned price range, this washer, with 2.5 GPM (gallons per minute), is placed on the lower end of the GPM scale. If maximum rinsing efficiency is your top priority, one of the devices with the highest water flow in the same price range is the A-iPower APW4200, with a GPM of 4.
  • The ALH3225-S's Cleaning Units, 8000 CU (PSI x GPM), fall into the lower end when compared to gas-powered devices of similar price. If you are after the highest overall cleaning power, the A-iPower APW4200 with its 16800 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 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.
