MEKOH 16.5” Pressure Washer Surface Cleaner, Large Lightweight Driveway Pressure Washer Attachment 3600PSI, 4 Caster Wheels, 1/4” Quick Connect, Universal Gas & Electric Power Washer Surface Cleaner vs Westinghouse ePX3500 Electric Pressure Washer, 2500 Max PSI 1.76 Max GPM with Anti-Tipping Technology, Onboard Soap Tank, Pro-Style Steel Wand, 5-Nozzle Set, for Cars/Fences/Driveways/Home/Patios

Price and Value Comparison

The MEKOH 16.5” Pressure Washer Surface Cleaner is priced at $39.99, while the Westinghouse ePX3500 Electric Pressure Washer costs $169.00—making the MEKOH nearly 76% cheaper. This significant price difference reflects a fundamental distinction: one is an accessory, the other is a complete pressure washing system. The MEKOH attachment offers a low-cost upgrade for users who already own a pressure washer, delivering immediate efficiency gains without requiring a new machine. In contrast, the Westinghouse unit represents a full investment in cleaning power, including a pump, motor, hose, wand, and soap tank. For someone seeking a standalone solution, the higher upfront cost is justified by the included components and functionality. However, if you’re already equipped with a pressure washer, the MEKOH provides exceptional value per dollar spent.

Cleaning Efficiency and Performance

The MEKOH surface cleaner dramatically improves cleaning speed and coverage by transforming a slow, manual process into a fast glide. Its wide cleaning path and spinning jets allow users to cover large flat surfaces like driveways and patios in significantly less time than traditional wands. While it doesn’t specify PSI or GPM values, its design enables efficient, streakless results across concrete, wood decks, and pavers. The Westinghouse ePX3500, on the other hand, delivers 2500 max PSI and 1.76 max GPM (at lowest pressure), providing strong water pressure ideal for tackling tough grime on cars, fences, driveways, and patio furniture. It also features a 2000 rated PSI and 1.2 rated GPM flow, ensuring consistent performance under load. The Westinghouse’s higher pressure output makes it better suited for heavy-duty cleaning tasks that require more force.

Portability and Maneuverability

The Westinghouse ePX3500 is engineered for ease of movement with four quick-lock wheels and a 360° steering design, combined with a low center of gravity and anti-tipping technology. At just 19 pounds and 16.5 inches tall, it’s compact and lightweight, making it easy to store and transport. The MEKOH surface cleaner also includes four caster wheels, enabling smooth rolling over concrete surfaces with minimal effort. However, unlike the Westinghouse, it lacks built-in mobility features such as a handle or upright design—it’s meant to be pushed manually behind an existing pressure washer setup. The Westinghouse’s integrated wheel system and balanced build make it far more portable as a standalone unit, especially when moving between different areas of a yard.

Design and Build Quality

The MEKOH surface cleaner is described as “built tough” and designed to fit right on compatible pressure washers, emphasizing durability and proper fit. Its splash-resistant skirt prevents messy sprayback, keeping users clean and containing debris during operation. The Westinghouse ePX3500 features a pro-style steel extendable wand and a durable construction with a 3-year limited service, labor, and parts coverage. It includes a 20-ounce onboard soap tank and a 25-foot easy-coil nylon braided hose, all contributing to a robust, professional-grade design. Both products prioritize longevity, but the Westinghouse’s comprehensive warranty and inclusion of multiple accessories suggest a more complete, long-term investment in reliability and maintenance support.

Ease of Use and Features

The Westinghouse ePX3500 enhances user convenience with several built-in features: a Total Stop System that automatically shuts off the pump when the trigger isn’t engaged, conserving energy and extending pump life. It comes with a five-nozzle set (0°, 15°, 25°, turbo, and soap applicator) and a quick-connect system for rapid nozzle changes. The MEKOH surface cleaner uses a 1/4” quick connect, allowing fast attachment to most pressure washers, and its design eliminates back strain through lightweight construction and smooth-rolling wheels. The Westinghouse’s onboard soap tank simplifies detergent application, reducing the need for external containers. Both tools aim to reduce physical effort, but the Westinghouse offers greater automation and versatility through its integrated systems.

Target Use Cases and Ideal Users

The MEKOH surface cleaner is best suited for homeowners who already own a pressure washer and want to streamline driveway, patio, or garage floor cleaning. It’s ideal for those prioritizing speed, reduced physical strain, and even cleaning results without investing in a new machine. The Westinghouse ePX3500 targets users seeking a complete, self-contained pressure washing solution—perfect for car detailing, fence cleaning, deck maintenance, and general home exterior upkeep. Its anti-tipping design and portability make it suitable for frequent use across varied outdoor spaces. If you’re starting from scratch or want a one-stop cleaning system, the Westinghouse is the logical choice. If you’re looking to enhance an existing setup, the MEKOH delivers high impact at a fraction of the cost.

Which should you buy?

Choose the MEKOH 16.5” Pressure Washer Surface Cleaner if you already own a pressure washer and want to cut cleaning time by up to half—especially for large, flat surfaces like driveways and patios—while saving $129.01 compared to the Westinghouse. It’s the smarter, more affordable upgrade for experienced users focused on efficiency and comfort. Opt for the Westinghouse ePX3500 Electric Pressure Washer only if you need a complete, standalone cleaning system with built-in soap storage, anti-tipping stability, and powerful 2500 max PSI performance—ideal for first-time buyers or those wanting a versatile, all-in-one solution. The Westinghouse ranks #154 in bestseller rank, indicating strong market demand, but the MEKOH’s lower price and targeted function offer superior value for specific tasks.
