MEKOH 14” Surface Cleaner Attachment
Designed for large surface areas, the MEKOH 14″ surface cleaner is compatible with most electric or gas pressure washers and features dual rapid-spinning jets that deliver a wide, streak-free cleaning path. With a maximum 2500 PSI and 2.7 GPM, it cleans up to four times faster than traditional nozzles, making deck railings, planks, and adjacent concrete much quicker to restore. The ABS polymer housing resists impacts while staying lightweight for extended use, and a 1/4″ quick-connect fitting enables fast setup. Note: an adapter may be required for certain brands (Portland, Kärcher, Husky, PowerClean, Black & Decker models) to convert to 1/4” QC.
LWQ Pressure Washer
The LWQ unit offers up to 2.5 GPM and includes four quick-connect metal nozzles plus a foam cannon, enabling flexible cleaning of decks, driveways, and fences. Its dual-roller design aids mobility, while an anti-tipping base adds stability during use. The detergent bottle can hold chemicals without drawing them through the pump, and the unit supports both faucet and bucket water intake, providing versatility when cleaning areas without direct water access. This makes it a solid option for mid-size decking tasks where mobility and variety matter.
SIMPSON Cleaning 88282 Cleaner
This concentrated soap solution is designed for heavy-duty deck cleaning and can be used with pressure washers, automatic scrubbers, or steam cleaners. Its high concentration reduces the need for multiple products and is effective at cutting grease and grime on outdoor surfaces. While primarily a soap solution, it complements deck cleaning when combined with appropriate nozzle settings and temperature control, helping to lift staining without harming wood or composite materials.
Electric Pressure Washer – 2.5 GPM
This portable unit emphasizes mobility with a 20-foot hose and long power cord, plus a four-nozzle spray system and foam cannon. It’s well-suited to deck maintenance near yards or garages where outlets and water access vary. The anti-tipping base helps prevent accidents on uneven decking, while the dual-wheel design allows easy movement around steps and railings. It accommodates faucet or bucket water intake, making it flexible for different cleaning scenarios on wood and composite decks.
Westinghouse Universal 16.5” Surface Cleaner
With a 16.5-inch diameter, this surface cleaner is designed to cover wide, flat surfaces like decks and patios quickly and evenly. It’s compatible with a broad range of gas and electric washers due to its 1/4″ quick-connect fitting. The design emphasizes ease of use and professional results, helping homeowners achieve a uniform finish on deck boards and surrounding concrete without leaving swipe marks or uneven patches.
Westinghouse ePX3500 Electric Washer
Combining 2500 max PSI with 1.76 max GPM, the ePX3500 provides a balanced level of cleaning power for decks, fences, and patios. Features include a pro-style steel wand, onboard soap tank, and a 5-nozzle set, supporting a range of cleaning tasks from gentle deck maintenance to tougher grime. Its anti-tipping design and compact form factor make it a solid option for homeowners seeking reliability without bulk.
Buying Guide: Key Purchase Considerations
- Power and flow: For decking, aim for at least 2000-2500 PSI and 1.8-2.5 GPM. Higher PSI helps remove tough stains, but too much pressure on wood can cause damage; balance is essential.
- Surface cleaners: Wide-head attachments (like 14″ or 16.5″) dramatically improve deck cleaning speed and uniformity. They reduce streaks and edge damage along boards.
- Attachment compatibility: Check quick-connect fittings and ensure the unit works with your washer (electric or gas). Note adapter needs for certain brands.
- Mobility and ergonomics: Consider weight, wheels, and anti-tipping features, especially when cleaning elevated decks or uneven surfaces.
- Detergents and foam: Onboard or compatible foam cannons help with heavy grime. Ensure cleaners are suitable for wood and do not degrade finishes.
- Durability: Look for robust housings and corrosion-resistant components for long-term outdoor use.
- Water source flexibility: Units that accept bucket water in addition to a garden hose provide flexibility when full-house water access is limited.
- Maintenance: Consider units with easily replaceable parts and widely available accessories to extend lifespan and simplify upkeep.
- Safety: Use appropriate nozzle angles, avoid high-pressure direct hits on wood seams, and protect surrounding plants and electrical outlets.
- Budget and use-case: For big decks with extensive staining, a surface cleaner plus a sturdy pressure washer offers best efficiency. For portable tasks or tight spaces, a compact unit with multiple nozzles suffices.
