Investing in a high pressure water cleaner for your job site, farm, factory or business? Don’t spend a cent before checking our essential guide.

Commercial high pressure water cleaner units are known for their powerful engines, durable pumps and ceramic pistons. But the list of advantages goes on much longer. There are some quality manufacturers that build models designed to tackle your general business cleaning right through to the the toughest industrial grade tasks with ease.

Commercial high pressure water cleaner units are packed with features, accessories and high quality components to make them suitable for practically any application, from concrete cleaning, mechanics garages, removing mold and mildew, washing fencing and retaining walls…the list goes on!

Quality Commercial pressure washers are known for their powerful professional grade engines, durable brass head pumps, and anti-corrosive ceramic pistons.

What makes high pressure water cleaner different from Domestic Pressure Washers?

With higher pressures than domestic pressure washers, pro pressure washers are fast and effective. Whether you need to wash down equipment on the farm or in the factory, they will cut cleaning time so you can move onto the next job.

Commercial: Quality commercial grade pressure washers from brands such as Gerni, Crommelins, Subaru, AR Blue Clean will use brass pump heads which are stronger, can handle more intensive use and have a longer lifetime.
Quality commercial grade pressure washers will also use solid ceramic pistons to avoid corrosion and thus also extending the unit’s lifetime.

Domestic: Pressure washers built for home use will typically use an aluminum pump head and solid steel pistons. These are lighter in weight and suit household cleaning requirements. When looking at domestic washers, again its best to opt for a quality brand (as listed above) as they will use non-corrosive aluminum which will prolong the life of the unit, as compared to cheaper brands which are often prone to corrosion.

Electric, Petrol, or Diesel Commercial Pressure Washer?

Deciding between an electric, petrol and diesel powered commercial pressure washer is the first decision you need to make.

Commercial electric pressure washers are more powerful than their domestic counterparts, so they can tackle larger areas and work for longer. They are quieter than fuel-powered machines and can be used in certain areas (such as indoors, or around food etc.), often where fuel-powered machines cannot. You also won’t need to spend as much time and money maintaining the machine with servicing, fresh oil, fuel etc.

For business use, electric high pressure water cleaner models are typically used for light to medium tasks such as; agribusiness cleaning, small automotive garages, car rental companies, cleaning tools/equipment, small building facades, graffiti removal, sandblasting and more.

Petrol and diesel powered pressure washers are more powerful still and are used for medium to heavy grade cleaning tasks in commercial industry. They have the benefit of not being restricted to access of mains power and can handle regular, intensive use for larger tasks.

Good quality petrol powered high pressure water cleaner models are powered by the likes of Honda engines –  designed for professional and commercial requirements and built to handle intensive use over many, many years.

Petrol and diesel powered pressure washers are are designed for intensive use and are used for medium to heavy grade cleaning tasks in commercial industry.

Similarly, premium grade diesel powered pressure washers are powered by the likes of Subaru engines are designed for industrial grade tasks. When choosing between petrol or diesel pressure washers, it often comes down to what fuel your business is using for other power equipment such as generators, pumps, vehicles etc. Diesel engines don’t have to work as hard as petrol engines to get the same power output and have the benefits of longevity, whereas petrol engines are typically cheaper and there is a greater choice available.

Petrol and diesel powered pressure cleaners are most commonly used for commercial requirements such as; paint stripping, large shop front cleaning, washing down dusty & dirty machinery, construction & mine sites, concrete cleaning, vehicle fleets, agricultural and hire industries.

What size do I need?

When choosing a pressure washer for sale, an important thing to note is that you can actually clean just about anything with a pressure washer over time…for example, you could use a small, entry-level 1500PSI domestic pressure washer to clean a large semi-trailer truck, but it would take a very, very long time! So one of the key things you are buying is time; generally speaking, the larger the task, the larger the required pressure washer.

Be sure to consider not only the pressure rating (PSI) of a high pressure water cleaner, but also the flow rate (Litres per Minute). The combination of these two specifications on the pressures washer really tells the story of the cleaning power of the unit. This table provides a good guide for what sized pressure washer (in terms of PSI and Flow Rate) you should look for to undertake your commercial cleaning tasks:

Features to look for?

1. Thermal Relief Valve/Thermal Dump: You want a good quality unit that has Thermal Cutout in the electric models – This feature the motor cuts out when heating is excessive to protect the unit. For petrol and diesel models, you want a ‘thermal dump’ feature which involves a valve that releases water when pressure is built up, but the trigger of the gun is not pulled to release, also designed to protect your unit.

2. Robust build: If you are looking at a petrol or diesel unit for tough work sites like construction jobs or mine sites, then look for features like rugged steel roll over frames, anti-vibration mounts, pneumatic wheels and a rubber isolated engine mounting plate. Other options include models that can be built to satisfy mine-spec standards including fire extinguisher, bunding and safety stop.

3. Compatible Accessories: There are many types of additional compatible nozzles, guns, extension lances/hoses, surface cleaners that you can look for. Two of the most popular ones are:

Turbo heads / turbohammer nozzles / powerspeed nozzles – This kind of nozzle spins a zero degree spray in a wider circle at 3000 rotations per minute. The spinning water jet hits the surface area from multiple angles, quickly breaking down the substance you want removed. As a result, turbo nozzles can cut cleaning time significantly. Very popular for concrete/paving cleaning to rid of moss, mold, stains paint etc.

Commercial Surface Cleaner – designed for fast cleaning time of driveways, warehouse, floors, large paved areas, etc. It is easy to use, has minimal splash (ideal around buildings, shop fronts, paths) and is ergonomic in design. Similar to the turbo nozzles, but limits splash.

4. Quality Brand: opt for a quality brand with a solid warranty and national service support network. Its not worth going down the path of finding the cheapest pressure washer on eBay that has no brand recognition and no service agent backing. Not only will a quality brand have superior performance in areas such as design, ease of use, reliability and output, but you’ll experience a much longer life with a reputable washer as opposed to a cheap no name product.

    I’m looking for a pressure washer for general farm use such as equipment cleaning, what units would you recommend?

    • L Adams October 10, 2016, 8:14 am

      Hi Mark, typically for general farming duties, customers will opt for a petrol powered pressure washer (opposed to electric) as they will often need to use it in places where they do not have easy access to mains power. I would recommend a unit powered a high performing engine from the likes of a Honda or Subaru – this also means you get national service agent and spare parts support for the engine. Two popular units for your type of application are:

      Gerni Poseidon 3-39PE Honda Powered Petrol Pressure Washer, 2400PSI
      Crommelins Subaru 3200PSI Pressure Washer

    Hi Steve
    I am after a cleaner for our mining equipment mainly (350 hitachi and haul truck) so not small equipment.
    Want to wash down engine (remove leaking hydraulic oil around hoses etc) with same cleaner, as well as mud etc from tracks of the machine.
    Use diesel on remote site however can use petrol as the cleaner would be used only once a week, if that.

      Hi Buddy, for your type of application we would suggest a pressure washer with a water flow rate of around 14-15 litres per minute and above. This kind of rate will make quick work of your described cleaning, including oil, mud etc. The most popular models for washdown of larger machinery/equipment are:

      Crommelins Subaru 4000psi Pressure Washer, 14hp – Pertol powered unit with 15 Litres/min flow rate. Also a popular model in the hire/rental industry for various different general commercial grade cleaning tasks.

      Gerni MC 5M 250/1050PE Plus, Petrol Honda Pressure Washer, 3625PSI – Honda powered petrol unit with 15 Litres/min flow rate. Often the Turbohammer nozzle is purchased with this as an additional accessory to deal with particularly hard to remove stains.

      Crommelins Subaru 3000PSI Diesel Professional Pressure Washer – Diesel powered unit with 15 Litres/min flow rate. Diesel units are more expensive, but they are electric start and this unit can be fully equipped with bunding, safety stop and extinguishers if required. Popular for mine sites.
