Westinghouse WPX3800 Gas Pressure Washer - Powerful 3800 PSI Cleaner

Our review of the Westinghouse WPX3800 finds it best suited for homeowners and DIYers who need a heavy-duty, mobile pressure washer for routine and deep-cleaning tasks. The single biggest reason to consider the WPX3800 is its combination of a 3800 PSI rating and a 3.6 GPM flow, which delivers genuinely tough cleaning power for driveways, decks, siding and patios while still being simple to move and operate. It balances engine performance, a brass head pump and practical features like an onboard soap tank to tackle stubborn grime without professional help.

Key Features

• High cleaning power: 3800 PSI with 3.6 GPM provides strong surface cleaning force for concrete, wood and siding.
• Durable pump and engine: the maintenance-free triplex brass head pump and 274cc OHV engine are built for repeated heavy use.
• Onboard soap tank: the 0.8 gallon soap tank lets you apply detergent for mold, mildew and oil removal without extra equipment.
• Mobility and reach: 12 in high profile never-flat wheels and a 35 ft abrasion-resistant hose make it easy to move and clean wide areas.
• Complete starter kit: comes with five quick-connect nozzles, spray gun, wand, engine oil and tools so you can get started in minutes.

Who It's For

The WPX3800 is ideal for homeowners with medium to large yards or multiple exterior surfaces to maintain, including patios, walkways, fences and vehicle exteriors. It suits anyone who values a powerful gas unit with an onboard soap tank and a durable pump for frequent heavy cleaning jobs.

It is less appropriate for users who need a lightweight electric option for occasional light-duty tasks or for apartment dwellers who cannot store or operate a gas-powered unit. If low noise, zero emissions, or ultra-compact storage are priorities, consider an electric model instead.
