Supply Hose

Pressure washers are powerful tools designed to clean surfaces with high-pressure water. They are used for various tasks, from cleaning driveways and sidewalks to washing cars and boats. However, one question often arises: do all pressure washers need a hose? This article delves into the necessity of hoses for pressure washers, exploring the types of pressure washers available, their mechanisms, and alternative water sources. By the end, you will have a comprehensive understanding of whether a hose is essential for all pressure washers.

Understanding Pressure Washers

What is a Pressure Washer?

A pressure washer is a mechanical sprayer that uses high-pressure water to remove dirt, grime, mold, and other contaminants from surfaces. The machine increases water pressure from a typical household hose to a much higher level, making it easier to clean tough stains and debris.

Types of Pressure Washers

There are two main types of pressure washers: electric and gas-powered. Each type has its own set of advantages and is suited for different cleaning tasks.

Electric Pressure Washers

Electric pressure washers are powered by electricity and are typically more compact and quieter than gas-powered models. They are ideal for light to medium-duty tasks, such as cleaning patios, outdoor furniture, and cars. Electric pressure washers are also easier to maintain, as they do not require fuel or oil changes.

Gas-Powered Pressure Washers

Gas-powered pressure washers are more powerful than electric models and are suitable for heavy-duty cleaning tasks. They can clean large areas like driveways, decks, and siding more effectively. However, they are louder, heavier, and require regular maintenance, including oil changes and fuel refills.

How Pressure Washers Work

Pressure washers operate by drawing water from a source, pressurizing it, and forcing it through a nozzle at high speed. This process involves several components, including:

  • Water Inlet: The water inlet connects the pressure washer to the water source, usually a garden hose.
  • Pump: The pump is the core of the pressure washer, responsible for increasing water pressure.
  • High-Pressure Hose: The high-pressure hose carries the pressurized water from the pump to the spray gun.
  • Spray Gun and Nozzle: The spray gun controls the flow of water, and the nozzle determines the spray pattern and pressure.

The Role of the Hose in Pressure Washers

Connecting to a Water Source

For a pressure washer to function, it needs a consistent supply of water. Typically, this is achieved by connecting the pressure washer to a garden hose. The garden hose supplies the necessary water to the machine, which the pump then pressurizes.

Types of Hoses

There are two main types of hoses associated with pressure washers: the supply hose and the high-pressure hose.

Supply Hose

The supply hose, often a garden hose, connects the pressure washer to the water source. It is usually made of flexible material like rubber or vinyl and comes in various lengths and diameters. The quality and diameter of the supply hose can affect the performance of the pressure washer, as a wider diameter hose can deliver more water.

High-Pressure Hose

The high-pressure hose carries the pressurized water from the pump to the spray gun. These hoses are designed to withstand high pressures and are reinforced with materials like steel mesh or wire braiding. They are typically more rigid and durable than supply hoses.

Importance of a Hose in Pressure Washers

The hose is a critical component of a pressure washer, as it ensures a continuous water supply and delivers high-pressure water to the spray gun. Without a hose, the pressure washer would not have the necessary water flow to operate effectively.

Alternatives to Traditional Hoses

While traditional garden hoses are the most common water source for pressure washers, there are alternative methods to supply water. These alternatives can be particularly useful in situations where a garden hose is not available or practical.

Water Tanks

Some pressure washers are designed to draw water from a stationary or portable water tank. These models are equipped with a suction hose that can be submerged in the tank, allowing the machine to draw water as needed. This setup is beneficial for remote locations without a readily available water supply.


For small-scale cleaning tasks, some pressure washers can draw water from a bucket. These models typically have a siphon tube or a built-in reservoir that can be filled with water. While not as convenient as using a hose, this method allows for greater flexibility in water sources.

Rain Barrels

Using a rain barrel as a water source is an eco-friendly option. Rain barrels collect and store rainwater, which can then be used to supply a pressure washer. This method requires a compatible pressure washer that can draw water from a lower-pressure source.

Direct Water Connections

In industrial or commercial settings, pressure washers may be connected directly to a water line. This setup ensures a constant and reliable water supply, eliminating the need for a garden hose. These systems are typically more complex and require professional installation.

Pressure Washers Without Hoses

Portable and Handheld Models

Some portable and handheld pressure washers are designed to operate without a traditional garden hose. These models are typically battery-powered and have built-in water reservoirs. They are convenient for small tasks and areas where connecting a garden hose is impractical.

Battery-Powered Pressure Washers

Battery-powered pressure washers offer the convenience of mobility and do not require a power cord or a garden hose. They have built-in tanks that hold a limited amount of water, making them suitable for light-duty cleaning tasks. These models are ideal for cleaning bikes, small patios, and outdoor furniture.

Handheld Pressure Washers

Handheld pressure washers are compact and easy to use. They usually come with a built-in water tank or a suction tube that can draw water from a bucket or other container. While they lack the power of full-sized pressure washers, they are perfect for quick cleanups and small jobs.

Pros and Cons of Pressure Washers Without Hoses


  • Portability: Without the need for a garden hose, these pressure washers are highly portable and can be used in remote locations.
  • Convenience: Built-in water tanks eliminate the need for a continuous water supply, making them easy to set up and use.
  • Compact Size: These models are typically smaller and lighter, making them easy to store and transport.


  • Limited Water Supply: The built-in tanks have limited capacity, requiring frequent refills for larger cleaning tasks.
  • Lower Pressure: Portable and handheld models generally have lower pressure compared to traditional pressure washers, limiting their effectiveness for heavy-duty cleaning.
  • Battery Life: Battery-powered models are limited by battery life, which can restrict the duration of use.

When a Hose is Essential

Large-Scale Cleaning Tasks

For large-scale cleaning tasks, such as washing driveways, decks, or siding, a traditional pressure washer connected to a garden hose is essential. The continuous water supply provided by a garden hose ensures that the pressure washer operates at peak performance without interruptions.

High-Pressure Cleaning

High-pressure cleaning requires a consistent and powerful water source. Garden hoses can supply the necessary water volume and pressure to maintain the performance of high-powered gas or electric pressure washers. This is crucial for tasks that require deep cleaning and removal of tough stains.

Professional Use

In professional cleaning scenarios, reliability and efficiency are paramount. Professional-grade pressure washers are designed to handle demanding tasks and require a steady water supply, often provided by a garden hose or a direct water line connection.
