Why Go Cordless?

Pressure washer manufacturers came up with a solution to this with the portable pressure washer. But they needed a power source to run and this was usually a plug that connected to the cigarette lighter socket in a car. Now there are cordless pressure washers that use a rechargeable battery.

This gives you the absolute freedom to use them anywhere with no restrictive cables and they can be supplied with water from a bucket or container. No restrictions from power cords or hoses connected to taps means total portability and the ability to pressure wash:

  • Mountain bikes
  • Boats
  • Off-road vehicles
  • Canoes
  • Remote properties not connected to utilities
  • Cleaning walking boots
  • Cleaning outdoor furniture
  • Kennels
  • Aviaries
  • Caravans
  • Cars
  • Gutters
  • Barbeques
  • Children’s toys
  • And many other places with no electricity or water.

How Do Cordless Pressure Washers Work?

Cordless pressure washers work in the same way as corded pressure washers only using a rechargeable battery instead of a direct electric current. Many have onboard water tanks, making them completely portable and not reliant on any external hoses or cables. The water passes through an internal pump that increases the pressure of the water to enable easy cleaning.

Effectively, a cordless pressure washer provides most of the advantages of an electric pressure washer with the portability of a petrol-powered model. They do lack power, unfortunately, but the extra freedom and portability make up for the lower power.

What Are The Benefits Of A Cordless Pressure Washer

The advantages of a cordless pressure washer outweigh the disadvantages in most cases. The benefits are:

  • No annoying cord
    The power cord on an electric-powered pressure washer can be restricting and in the wrong circumstances dangerous. Cordless models remove the danger and the restriction giving you the freedom to move without hindrance and the ability to clean almost anywhere.
  • Compact
    Easy to carry and small enough to fit into the boot of a car with no problem.
  • Lightweight
    Compared to a corded model, cordless pressure washers are lightweight and easier to move around.
  • Ability to use water from nearly any source
    Rather than just relying on a garden hose for water, cordless models are capable of using buckets, water butts, containers, wells, anywhere the suction hose can fit into basically.
  • Convenient to use
    As there’s no power cord to plug in, a cordless power washer is so simple to set up and use. You’ll be getting it out just as often as you can, just for the fun of it.

What Are The Disadvantages Of Cordless Pressure Washers?

As cordless pressure washers are a fairly new innovation, there are a few disadvantages, they are:

  • Expensive
    This will change as more companies introduce their own cordless models, but currently, cordless pressure washers are as expensive or dearer than electric-powered pressure washers.
  • Short battery life
    On a full charge you can just about squeeze 20-minutes of run time on high-power from the Li-Ion battery. Which takes an average of 5-hours to reach full charge.
  • Low-powered
    The top Pound per Square inch (PSi) for a cordless pressure washer is around 800 PSi. Whereas, electric-powered models start at around 1400 PSi, and rise to around 2000 PSi. So you can expect half to one third the power from a cordless compared to a corded model.
  • Lower flow rate
    The low power means the flow rate is lower too. On decent cordless models, the flow rate is around 0.79 Gallons Per Minute (GPM). Electric-powered models tend to start at around 1 GPM and rise to around 2.5/3.0 GPM. The higher the flow rate the faster it will clean.

Cordless Pressure Washer Buyers Guide

Before buying a cordless pressure washer here are a few points to consider.

Accessories

Before you make your purchase, check exactly what you are getting, as it seems to be quite common to not get everything you’ll need straight out of the box. Some models supply a battery pack but no high-pressure hose, others vice versa and some have no tools etc while others have everything you’ll ever need and more.

Water Pressure 

This will either be quoted in bars or PSi. Bars measure the rate of energy the water will hit the object you are cleaning. 1 bar is equivalent to 14.4 PSi. PSi is Pounds per square inch of energy hitting the object you’re cleaning. So they measure the same thing only they express it in a different way. The higher the pressure rating, the more cleaning power you will have.

Flow Rate

The flow rate is measured in Gallons Per Hour (GPH) or Litres Per Minute (LPM) This is how much water flows through the pressure washer per time frame, either per hour or per minute. If you’re planning on using multi-nozzles you’ll need a flow rate of at least 13 LPM (171  GPH).

Onboard Water Tank

Some cordless models have an onboard water tank. This is handy as you don’t have to endure the constraints of dragging a supply hose around with you. But onboard water storage will increase the overall weight of your machine. Each litre of water weighs 1 Kg So be sure to factor that extra weight into any weight considerations.

For instance, a cordless pressure washer might only weigh 7 Kg when empty but if it has a 20-litre tank, that’s almost 4 times the weight full to empty. They often come on wheels but the weight can be a problem for the elderly or infirm.

Water Tank Size

The size of the onboard water tank can vary, consider how much water the average cleaning job requires, then see if the tank has the capacity. If not you will have to stop and refill the tank before continuing with the job.

Design

Some models seem to have been designed by very practical people, everything has a place, and all of the accessories can be stored onboard etc. Others are a struggle as soon as you get them out of the box. 

Robustness

Look for a model that looks like it can take a bit of misuse. I don’t mean neglect your pressure washer, but some models are sturdier than others and can take a few accidental knocks.

Wheels

Some cordless models come with fitted wheels, these can be very handy especially if the water tank is full. It saves struggling to carry 27 Kg of weight, just wheel it into position and start cleaning. Also how large are the wheels? Are they robust enough?

Attachments

Brushes, wands, gutter cleaners, etc, some models come supplied with these as standard, in others they are extras. Do your research before you buy to be sure to get the attachments you need.

Battery Charge Time

How long does the battery pack take to fully charge? How long will that charge last? Does the pressure washer come with a spare battery pack? Or can you buy a spare for convenience?

Pressure Settings

Does the pressure washer have pressure settings? If so, how many?

High-Pressure Hose

How long is the high-pressure water hose?  We find the longer the better, but that’s our preference. Some people like the hose shorter so they cannot trip on it.

How Many Spray Patterns 

The spray gun should have at least 3 spray patterns. Some include a shower pattern that is safe enough to use on pets.

Nozzles

The nozzles determine the spray pattern, so you’ll either have a spray gun with a swivel action to change spray angle or interchangeable nozzles. Check that the model you choose has all that you need.

Suction Hose

Some cordless pressure washers have a suction hose allowing you to draw water from buckets, water butts, wells etc. Some need to be filled manually.

Water Filter

Does it have a water filter so any foreign bodies in the water from a water butt etc don’t clog the jets up on the spray head?

What’s The Working Time?

This is really how long does the battery keep its charge in full use? Some of the better models last up to 60 minutes.

Storage Space

How compact does the pressure washer become when storing? Some models have onboard tool holders etc.

How Easy Is It To Set Up

Some models are simple to set up and operate, others need an engineer to explain it in detail. Check that you understand how to set yours up before starting.

Power

There are 2 types of cordless pressure washers, one has a rechargeable battery, and the other is hand primed and works simply on air pressure. The hand primed models have less power, less water capacity and less cleaning power.

Detergent Bottle

Just like their electric counterparts, cordless pressure washers can have detergent bottle attachments. Some have built-in detergent bottles, Check that the model of your choice has the type you prefer.

Coins

How Much The Cordless Pressure Washer Costs

As this technology is improving at an exponential rate, new cordless models become available almost every week. So the cost can vary greatly.

  • The hand primed model is around £20
  • Handheld multi-jet cordless are around £90
  • A compact model is around £80
  • Top of the range models top out at around £250

Brand

Buying a well-known brand from an established manufacturer is always favourable. Because their machines are usually more reliable and in the unlikely event of it developing a fault, they will have a decent customer service department to offer good advice or honour any warranty agreement.

Guarantee

Most appliances come with a manufacturers guarantee and guarantees for cordless pressure washers tend to be for a minimum of 12 months and up to a maximum of 3 years. Some have the option of extending them beyond their stated time. Any warranty is only as good as the company that issues it. Which is why we always recommend using a reputable retailer and buying from a well-known brand.
