Simpson Cleaning ALH4240: A Deep Dive Review
The Simpson Cleaning ALH4240 is a gas-powered pressure washer designed for heavy-duty residential and light commercial use. Its key selling points include its Honda GX270 engine, a robust triplex pump, and a sturdy steel frame. Let's break down its features, performance, and overall value.
Key Features and Specifications
Before getting into the nitty-gritty of performance, let's outline the core specifications of the ALH4240: Engine: Honda GX270 OHV Engine Pump: AAA Triplex Plunger Pump PSI (Pounds per Square Inch): 4200 PSI GPM (Gallons per Minute): 4.0 GPM Hose Length: 50 ft. Nozzles: 5 Quick Connect Nozzles (0°, 15°, 25°, 40°, Soap) Frame: Welded Steel Construction Tires: 13" Premium Pneumatic Wheels Weight: Approximately 128 lbs Warranty: Limited Warranty (Engine and Pump have separate warranties. Check Simpson Cleaning website for details.)
Unboxing and Assembly
The ALH4240 typically ships partially assembled. Expect to attach the handle, wheels, and some hoses. The included instructions are generally clear, but some users may find it helpful to watch a setup video online.
Assembly Tips
Read the Manual: Don't skip this step! Understanding the components and assembly process will save you time and frustration. Engine Oil: The engine likely ships without oil. Be sure to add the correct type and amount of oil before starting the engine for the first time. Check the Honda GX270 engine manual for specific oil recommendations. Hose Connections: Ensure all hose connections are tight to prevent leaks. Using Teflon tape on threaded connections can also help. Wheel Installation: Properly secure the wheels to ensure smooth maneuverability.
Performance and Cleaning Power
The combination of the Honda GX270 engine and the AAA triplex pump delivers exceptional cleaning power. The 4200 PSI and 4.0 GPM figures translate to effective grime removal on a variety of surfaces.
Driveways and Sidewalks: The ALH4240 makes quick work of removing dirt, algae, and mildew from concrete surfaces. Using the 15° or 25° nozzle is generally recommended for these tasks. Vehicles: With the appropriate nozzle (40° or soap nozzle), the pressure washer can be used to safely clean cars, trucks, and boats. Be cautious not to use too much pressure, which could damage the paint. Decks and Fences: The ALH4240 can effectively clean wood surfaces, removing stains and preparing them for painting or staining. Test a small, inconspicuous area first to ensure the pressure doesn't damage the wood. Heavy-Duty Cleaning: For tough jobs like removing graffiti or stripping paint, the 0° nozzle provides concentrated cleaning power. However, use extreme caution with this nozzle, as it can easily damage surfaces.
Real-World Example: I recently used the ALH4240 to clean a heavily soiled concrete patio. After applying a pressure washer-safe detergent with the soap nozzle, I used the 25° nozzle to blast away years of accumulated grime. The results were remarkable, leaving the patio looking almost new.
Ease of Use and Ergonomics
Despite its power, the ALH4240 is relatively easy to use. The quick-connect nozzles make it simple to switch between different spray patterns. The 50-foot hose provides ample reach, allowing you to clean large areas without moving the unit frequently. The 13" pneumatic tires contribute to smooth maneuverability, even on uneven terrain.
However, the weight of the unit (around 128 lbs) can be a factor when lifting or transporting it.
Noise Level
Gas-powered pressure washers are inherently noisy. The ALH4240 is no exception. While the Honda GX270 engine is known for its relatively smooth and quiet operation compared to some other engines, wearing ear protection is still recommended, especially during prolonged use.
Maintenance
Proper maintenance is crucial to prolonging the life of your pressure washer. Here are some key maintenance tasks: Engine Oil Changes: Follow the Honda GX270 engine manual's recommendations for oil change intervals. Pump Saver: Using a pump saver solution before storing the pressure washer helps protect the pump from damage caused by freezing temperatures or mineral deposits. Air Filter Cleaning: Regularly clean or replace the air filter to ensure optimal engine performance. Spark Plug Maintenance: Inspect and replace the spark plug as needed. Hose Inspection: Check the hose for cracks or leaks and replace it if necessary. Nozzle Cleaning: Keep the nozzles clean to ensure proper spray patterns. Use a nozzle cleaning tool to remove any debris.
