Overview of the Products
The MEKOH Pressure Washer Surface Cleaner 20'' is designed as an attachment for pressure washers, while the Simpson 3400 PSI Gas Pressure Washer is a standalone unit. The MEKOH attachment retails for $209.99, making it about 36% cheaper than the Simpson, which is priced at $329.00. This price difference highlights the options available depending on your needs—whether you're looking for a full pressure washing solution or an accessory to enhance your existing setup.
Cleaning Performance
MEKOH’s surface cleaner boasts a superior cleaning performance due to its two high-pressure jets that provide non-marking cleaning. This attachment can clean surfaces eight times faster than traditional nozzles, making it highly efficient for large areas. On the other hand, the Simpson pressure washer delivers 3400 PSI at 2.5 GPM, making it powerful enough for various cleaning tasks like driveways and patios. While both products excel in cleaning ability, the MEKOH may be more efficient for larger flat areas, whereas the Simpson provides a versatile solution for multiple cleaning scenarios.
Ease of Use
The MEKOH attachment features four universal wheels and two angle-adjustable handles, making it easy to maneuver across surfaces. This design allows users to operate it with minimal effort, enhancing the cleaning experience. Conversely, the Simpson pressure washer includes 10” pneumatic tires that roll smoothly over uneven terrain, allowing for easy transport. Both products are designed with user convenience in mind, but the MEKOH might be more appealing for those who prioritize ease of operation when cleaning expansive areas.
Build Quality
MEKOH uses lightweight and environmentally friendly materials in its surface cleaner, claiming solid brass construction and fully sealed bearings to prevent leaks. This design is coupled with a heavy-duty construction that can withstand high pressure and chemical exposure. The Simpson pressure washer features a welded steel frame with a powder-coated finish, ensuring durability and resistance to corrosion. While both products are built to last, the Simpson's robust frame may offer an edge in long-term durability for frequent users.
Versatility
The MEKOH pressure washer surface cleaner is designed specifically for larger flat surfaces like driveways and patios, providing efficient cleaning for these areas. It also allows users to switch between different cleaning patterns with changeable nozzles. In contrast, the Simpson pressure washer is equipped with four quick-connect nozzles (0°, 15°, 40°, and soap), making it versatile for various tasks ranging from washing cars to cleaning windows. If versatility across different tasks is a priority, the Simpson may be the better choice.
Maintenance and Care
The MEKOH attachment's design aims to minimize maintenance with its upgraded bearings preventing leaks and blockages. This focus on reducing upkeep is beneficial for users who want to spend more time cleaning than maintaining their equipment. On the other hand, the Simpson pressure washer features a maintenance-free OEM Technologies axial cam pump, which includes a thermal relief valve to prevent overheating. While both products are relatively low maintenance, the Simpson’s built-in features designed for ease of use can provide peace of mind for homeowners.
Price Comparison
With the MEKOH priced at $209.99 and the Simpson at $329.00, there is a significant difference of $119.01, making the MEKOH about 36% cheaper. This price point can greatly appeal to budget-conscious consumers who need effective cleaning solutions without breaking the bank. However, the higher price of the Simpson could be justified for those seeking a powerful, standalone pressure washer that offers versatility for a variety of cleaning tasks.
Which should you buy?
Choosing between the MEKOH Pressure Washer Surface Cleaner and the Simpson 3400 PSI Gas Pressure Washer ultimately depends on your specific cleaning needs. If you're looking for an efficient attachment that excels in cleaning large flat surfaces and is budget-friendly, the MEKOH is an excellent choice. However, if you require a more powerful, versatile cleaning machine capable of handling multiple tasks, the Simpson pressure washer may be worth the investment, despite its higher price. Consider how you plan to use the product to make the best decision for your home cleaning needs.
