DESCRIPTION

300 PSI 11.0 GPM Gas Direct Drive Commercial Mobile Soft Wash System with Electric Start

The BE Power Equipment SW1165HEZ is a commercial-grade mobile soft wash system delivering 300 PSI at 11.0 GPM, designed for professional contractors who need low-pressure, high-volume cleaning for surfaces that cannot tolerate the force of a conventional pressure washer. Soft washing uses chemical solution, not water pressure, as the primary cleaning agent. The high-volume flow carries detergent to the surface and rinses it thoroughly, while the low pressure protects roofing materials, wood structures, painted siding, stucco, and other delicate substrates from damage.

Powered by a Honda GX200 196cc engine with recoil and electric start and built around a CP Z42PPGR diaphragm pump rated for professional soft wash applications, the SW1165HEZ is a gas direct drive platform with a pump operating speed of 550 RPM. Built on an aluminum mobile cart frame with easy bolt-down installation for truck or trailer mounting, the SW1165HEZ is a complete commercial soft wash platform ready for daily professional use.

What Is Soft Washing?

Soft washing is a low-pressure cleaning method that uses specific detergents and high water volume to remove biological contaminants such as algae, mold, mildew, lichen, and organic staining from building surfaces. Unlike pressure washing, which relies on water force to remove dirt, soft washing relies on the chemical solution to break down and kill contaminants at the source, with the water volume delivering and rinsing the solution.

Soft washing is the recommended method for:

  • Asphalt shingle and tile roofing
  • Wood siding, decks, and fences
  • Painted and stucco exterior surfaces
  • Cedar and composite cladding
  • Screens, gutters, and fascia
  • Commercial building exteriors where pressure washing would void warranties or cause damage

Features

Honda GX200 Engine

The SW1165HEZ is powered by the Honda GX200 196cc OHV engine with recoil and electric start, a commercial-grade engine with an excellent power-to-weight ratio built for continuous all-day use. Key engine features include:

  • Recoil and electric start for reliable, convenient starting
  • Fuel-efficient OHV design for extended run times
  • Automatic low-oil shutdown to protect the engine
  • 3.1 L / 0.8 GAL fuel tank

The Honda GX200 engine is covered under Honda's separate engine warranty program.

CP Z42PPGR Diaphragm Pump

The heart of the soft wash system is the CP Z42PPGR diaphragm pump, designed for commercial soft wash performance where high water volume and low operating pressure are required. The pump runs at a 550 RPM operating speed, which helps reduce pump wear, improve durability, and maintain consistent soft wash performance throughout extended commercial cleaning sessions. Key pump features include:

  • High-volume flow at 11.0 GPM for efficient surface coverage and rinsing
  • Low operating pressure at 300 PSI: safe for delicate exterior surfaces
  • Diaphragm design built for professional soft wash applications
  • Maximum operating temperature of 140°F / 60°C
  • 1" inlet and 3/4" outlet for high-flow system compatibility
  • 1/2" bypass port

Single-Piece Manifold

The single-piece manifold design reduces the number of potential leak points compared to multi-piece manifold configurations, simplifying service and minimizing downtime in the field.

Bolt-On Regulator

The bolt-on regulator provides secure, leak-free pressure adjustment. The bolt-on mounting prevents the regulator from backing out or leaking when the pressure knob is adjusted during operation, a common failure point on soft wash systems with threaded regulators.

Aluminum Mobile Cart Frame with Truck Mount Capability

The SW1165HEZ is mounted on an aluminum mobile cart frame with stabilizing feet for ground-level use and easy bolt-down installation for mounting to a truck bed, trailer, or service vehicle. The aluminum construction keeps the unit lightweight relative to its pump capacity, and the bolt-down mounting pattern accommodates a wide range of vehicle configurations. The SW1165HEZ is Truck Mount Ready (TMR).

Warranty

The SW1165HEZ is backed by a multi-component warranty from BE Power Equipment:

  • Engine: 3-year limited warranty. The Honda GX200 is covered separately under Honda's manufacturer engine warranty program.
  • Pump: 5-year limited warranty

Each unit is functionally tested at the factory before shipping. The actual product may vary slightly from the images shown on the website.

Frequently Asked Questions about Pressure Washers

How to store a pressure washer?

To ensure the durability of your heavy duty pressure washer:

  • Empty the gas tank to prevent fuel from degrading or clogging the engine.
  • Empty the pump and hoses of any remaining water.
  • Perform necessary maintenance before storage.
  • Store in a dry area.
  • Cover.

What is a pressure washer?

A power washer is a cleaning machine that uses a gasoline engine to power a high pressure water pump and nozzle. It’s used to clean driveways, decks, vehicles, outdoor furniture and more by spraying water at high PSI to remove dirt, grime, mold and other debris.Many models also come with a detergent tank for added cleaning power.

How does a power washer work?

A power washer works by drawing water from a connected hose and pumping it through a high pressure nozzle. The gas engine powers the pump which pressurizes the water and then expels it through the nozzle at high speed to clean the surface. The water pressure is measured in PSI (pounds per square inch) and the flow rate is measured in GPM (gallons per minute).Many models also feature adjustable water pressure settings to cater to different cleaning needs. BE makes pressure washing easy with models available for light jobs and heavy duty commercial cleaning projects.

Gas vs Electric power washers?

The main difference is that a gas pressure washer, known for its cleaning power, is powered by a gasoline engine, making it more powerful and portable, while an electric pressure washer is powered by electricity and is generally quieter and lighter.

Gas pressure washers are for heavy duty and large areas due to their durability, whereas electric pressure washers are for smaller jobs.

Your BE electric pressure washer is perfect for smaller jobs and built for portability, and we offer a wide range of electric models. Included with our electric models is a long extension cord for use anywhere around your house.

What to consider?

When choosing a gas pressure washer consider:

  • Pressure (PSI): More PSI means more cleaning power but also more potential for damaging delicate surfaces.
  • Flow Rate (GPM): More GPM means faster cleaning as more water is dispensed.
  • Engine Power: Bigger engines mean more durability and power.
  • Portability: Weight, handle design and wheel size for easier to move.
  • Nozzles: Multiple spray nozzles to adjust the spray pattern for different tasks.
  • Adjustable Nozzle: Allows for fine-tuning the spray intensity and pattern for various cleaning needs.

How much pressure do I need for?

The required pressure (PSI) and cleaning power depend on the surface you’re cleaning:

  • Light duty (car washing, outdoor furniture): 1,300-1,800 PSI.
  • Medium duty (patios, fences, decks): 2,000-3,000 PSI.
  • Heavy duty (driveways, brick walls, large equipment): 3,000+ PSI.

Many pressure washers come with adjustable pressure settings to handle different cleaning tasks effectively.

Can a pressure washing damage surfaces?

Yes, a power washer can damage surfaces if used incorrectly. High pressure water can strip paint, dent soft surfaces or even cause structural damage if the pressure is too high or the nozzle is held too close to the surface. Always use the right PSI for the material you’re cleaning and keep a safe distance from delicate surfaces.

To prevent damage, consider using a model with adjustable pressure settings.

How to maintain your pressure washer?

To ensure the durability and smooth operation of a pressure washer:

  • Change the oil as per manufacturer’s instructions.
  • Clean or replace the air filter to ensure good airflow.
  • Inspect and clean the nozzle regularly to prevent clogs.
  • Drain the gas tank if you’re storing the washer for a long time.
  • Check the hoses for leaks or damage and replace them if needed.
  • Follow regular maintenance requirements to keep the washer in optimal condition.

Can I use a pressure washer in cold weather and low water temperature?

You can use a pressure washer in cold weather but it’s more difficult. The water flow rate in the hoses and pump can freeze and damage the equipment. If you plan to use your pressure washer in cold temperatures make sure to winterize it and store it in a warm area when not in use. You can also use anti-freeze solutions for pressure washers.

Some models are designed to use hot water, which can be particularly effective for cleaning in cold weather.
