The cordless pressure washer can be used to rinse cars, motorcycles, trucks, and bicycles. It will make your car shine even without power.

Cordless pressure washers require no wires and can be connected directly to a water hose, but some come with a water tank and are free of hoses! Usually, many electric pressure washers have 6-in-1 adjustable nozzles to suit your needs. It can be used for washing cars and watering lawns, cleaning backyards, driveways, crevices and more. Its cordless design allows it to travel anywhere.


A cordless pressure washer, also known as an electric pressure washer, a portable pressure washer, or a battery-powered pressure washer. It can eject high-pressure water through the outlet hose to clean your car, yard, motorcycles, trucks, and so on and has a high-pressure pump and is usually powered by a lithium-ion battery. The machine has a water inlet traditionally connected to a water pipe. However, some cordless, battery-powered devices are not connected to a hose but suck water directly from the tank. Other models have a detergent tank or soap dispenser. Often, there are different modes of nozzles.

Before buying a cordless electric washing machine, you should mainly consider the key indicators: noise level, water output and battery life. Next, let's take a closer look.

  • GPM vs PSI
Some ask which is better: gallons per minute or pounds per square inch. GPM represents how much water is being dispensed, while PSI shows how fast water is being delivered.

  • Noise
If you hate noisy environments, choose a less noisy washing machine. Although cordless models are less powerful, they are also less noisy. Typically, most models are below 85 decibels, except for noise and performance differences.

  • Battery life
If an electric pressure washer can't be plugged into an outlet, it won't work once it runs out of power. A greater flow rate or pressure will shorten its life. Therefore, the factor you need to consider is battery life. Bigger batteries last longer, but they are heavier and more expensive. You can buy smaller batteries. If they run out of power, you can replace them.

You can use soap, as long as there is a tank for holding soap. Not every machine has one, but a tank for holding soap is becoming increasingly popular. If it does not come with a detergent canister, you can use the attachment that adds soap. You won't need soap if you're just cleaning dirt and dust from the patio or balcony. However, if you want to clean oil stains, detergent is a must.

Many people use dishwashing detergents as the solution, but this is not wise and will not be as effective. Some detergents are designed for electric pressure washers that can give effective cleaning. The type of soap depends on the kind of cleaning and the type of machine.

Before we buy a cordless pressure washer, we make sure it can spray enough distance, whether it's a patio, a sidewalk, or a wall.

Typically, most machines can spray 20 feet or 6 meters. A home cordless pressure washer will produce 1000 - 4000 PSI. Industrial cordless pressure washers go up to 6000 PSI and can typically spray 40-60 feet.

In addition, their spray distance varies due to their power source, PSI, nozzle head and hose length. For more information, please click here .

1. Detergent flows in through a hose.

2. Water flows in through another hose and is filtered.

3. The motor or engine provides the power.

4. The water pump draws in the detergent and water. (Some models heat the water to 50-70°C.)

5. The water pump ejects the soapy water through the outlet hose. Some have narrow nozzles to increase the pressure of the water column further.

6. High-pressure water jets clean more effectively and save 80% water.
