Westinghouse ePX3500 Electric Pressure Washer
Designed for versatile cleaning power, the Westinghouse ePX3500 delivers up to 2500 max PSI with 1.76 max GPM. At the lowest pressure, it operates with 2000 PSI and 1.2 GPM, making it suitable for trailer exteriors, hitch areas, and decks without excessive water usage. A pro-style steel wand with quick-connect nozzles (0°, 15°, 25°, turbo, and soap) offers precise control for delicate trailer finishes or stubborn grime around axles and wheels. The unit is compact, weighing about 19 pounds and standing 16.5 inches tall for easy storage in a trailer compartment.
Mobility is enhanced by four quick-lock wheels with 360° steering and a low center of gravity to help prevent tipping on uneven loading ramps. An onboard 20-ounce soap tank lets you apply detergents directly to the surface, useful for removing road salt or grease around towing hitches and undercarriage areas. The 25-foot hose is nylon braided for durability, providing workable reach when cleaning trailers parked in driveways or yards.
Westinghouse ePX3100 Electric Pressure Washer
The ePX3100 offers 2300 max PSI and 1.76 max GPM, stepping down slightly from the ePX3500 but retaining anti-tipping technology and an onboard soap tank. Its compact, lightweight design (about 19 pounds) with a 16.5-inch profile makes it easy to maneuver around a trailer’s undercarriage or wheel wells. The product includes a pro-style steel wand and a 25-foot hose, expanding reach when cleaning hard-to-access areas beneath trailers parked in narrow bays or on steep driveways.
Five quick-connect nozzles (0°, 15°, 25°, turbo, and soap) provide flexibility for different surfaces—perfect for removing mud on trailer ramps, spray decks, and fenders without damaging paint or decals. The onboard soap keeps detergents away from the pump, supporting longer life for frequent trailer washings and seasonal maintenance tasks.
LWQ Pressure Washer With Foam Cannon
The LWQ model focuses on power and versatility, delivering up to 2.5 GPM and a deep-clean capability suitable for trailer maintenance. It ships with four quick-connect metal nozzles (0°, 15°, 25°, 40°) and a foam cannon, enabling foam-based pre-washing to loosen road grime on trailers, axles, and hitch assemblies. The detergent bottle can hold chemicals such as cleaners or degreasers without passing through the pump, protecting internal components during heavy-duty cleaning tasks.
Movement is facilitated by a wheeled design, with a two-roller setup and anti-tipping features, allowing you to move around the trailer and campsite without strain. The unit can pull water from a faucet or a bucket, offering flexibility when washing trailers in off-grid locations or during roadside maintenance where a garden hose isn’t convenient.
Westinghouse WPX3000e Electric Pressure Washer
The WPX3000e elevates cleaning power with 3000 max PSI and 1.76 max GPM, supported by a heavy-duty induction motor. This model is especially capable for trailer maintenance where robust cleaning is needed on concrete ramps, undercarriages, and exterior surfaces. A .45-gallon soap tank, a 25-foot abrasion-resistant hose, and a 5-nozzle spray gun (0°, 15°, 25°, soap, and turbo) provide a broad range of cleaning options, from delicate waxed surfaces to stubborn road grime around axles and tires.
Additional compatibility with surface cleaners, undercarriage cleaners, and foam cannons expands the range of trailer-specific tasks. The heavy-duty motor and auto-stop pump help sustain performance during frequent use, making it a practical option for frequent trailer washdowns or fleet maintenance operations.
Westinghouse Universal 16″ UnderCarriage Cleaner
This attachment is designed to complement trailer cleaning by targeting the undercarriage, mud flaps, and exposed wheel wells. It functions as both an undercarriage cleaner and a water broom, offering two modes for different cleaning tasks. With a max 4400 PSI rating, it can handle tough grime while remaining compatible with most gas and electric pressure washers via M22 1/4″ quick connectors. Using this accessory helps protect trailer frames and suspension from corrosive road grime and debris that can accelerate wear.
Combining the water broom mode with a compatible pressure washer expands your cleaning options for flat surfaces like driveways and ramps, keeping trailer bases and surrounding pavement safer and neater. Regular use can prevent buildup that complicates maintenance and inspections during trips or after storage.
Westinghouse Pressure Washer With High-Output Nozzles
This model emphasizes high-pressure cleaning with 3.0 GPM and up to 3,000 PSI, balancing efficiency and water use for trailer washing. It includes four quick-connect metal nozzles (0°, 15°, 25°, 40°) and a foam cannon for heavy buildup tasks. A 21-foot hose and a 17-foot power cord enhance mobility on a trailer or at a campsite. The detergent bottle can hold chemicals while preventing backflow into the pump, preserving pump life during frequent use on trailers with mud, salt, or tree sap on exterior surfaces.
Buying Guide: Key Considerations For Trailer Cleaning
When choosing a pressure washer for trailer maintenance, consider these factors to ensure reliable performance and long-term value:
- PSI and GPM balance: Trailers benefit from models that deliver sufficient PSI to dislodge mud and salt without damaging paint. Look for units in the 2000–3000 PSI range with 1.5–2.5 GPM for efficient cleaning.
- Mobility and storage: Choose compact, light units with wheels and ergonomic handles to maneuver around trailers and ramps. A low center of gravity helps prevent tipping when docked or loaded.
- Detergent compatibility: An onboard soap tank or detergent compatibility helps apply cleaners to wheels, undercarriages, and hitch areas. Detergent injection should protect the pump from chemical damage.
- Nozzle versatility: A set of quick-connect nozzles (0°, 15°, 25°, turbo) plus a foam cannon expands cleaning options for metal, painted surfaces, and textured undercarriage components.
- Accessories and extensions: Consider attachments such as undercarriage cleaners or water brooms for trailers. Compatibility with standard M22 fittings ensures easy expansion.
- Durability and warranty: Induction motors and robust pumps offer longer service life in outdoor environments. Check warranty terms for residential versus commercial use.
- Water source flexibility: Models that can draw from a faucet or bucket support remote locations or campsites where standard water access is limited.
For trailers, the emphasis is on protecting structural components like frames and axles while maintaining paint and decals from road grime. A model with a balance of power, portability, and accessory options provides the best long-term value for frequent trailer cleaning tasks.
