Best Commercial Heavy Duty Pressure Washer: Electric or Petrol?

Best Commercial Pressure Washer Table

How to Choose a Pressure Washer

Choosing a pressure washer is not always an easy task, even when you are purchasing a commercial one.

After all, there are a wide number of different models on offer and all at different prices. The first thing you need to do is ask yourself what kind of work you will be using the pressure washer for.

Is it for cleaning cars? Houses? Patios? Large industrial areas? Determining what you need it for is the first step to choosing the right one.

You also need to determine whether you want an electric pressure washer or a petrol one. The former can be cheaper to buy and run, but it has less power than a petrol pressure washer.

Petrol ones tend to be heavier and more industrial, and they offer some incredible power levels that electric ones are unlikely to be able to reach.

It’s all down to personal preference and the kind of commercial work you will be doing.

Next, is the concept of price. Are you on a budget or are you free to choose from each range level? Determining how much you have to spend can really help you to narrow down the machines that are on offer to you.

Along with this, you should ensure it is a machine you can handle in terms of weight. Is it on wheels? Is it lightweight or does it require additional support to lift? Knowing your limitations can help you to pick the best commercial model for you.

Is it from a brand you trust? Most pressure washers are manufactured by trusted brands like Wolf and Nilfisk.

While this does not guarantee quality every time, they have a good reputation because they tend to deliver reliable products. Always check to see what the brands you favour have first, as not every model from a big name costs a lot to buy.

Always take the time to read through the reviews before you make your purchase. If you aren’t sure which is best, the reviews from other customers can tell you a lot about the general level of satisfaction others have felt. This can aid in your decision making and help you with a potentially tricky decision.

Things to Look for

There are a few things you should keep an eye out for when you go to purchase your pressure washer. The first of these are the additional tools that it comes with.

This includes things like extra nozzles that allow for a more concentrated or relaxed spray. Some are even more specific, being made to deal with things like moss or hard to reach debris.

Extra tools can be a huge help when it comes to making your cleaning experience an easier and more efficient one.

You should also check to see if it comes with some sort of filter. These are able to protect the main mechanisms so that they are not damaged by debris when in use.

Checking to see if they come on wheels can also be handy for portability reasons, especially if you have to move it around a lot.

Storage for the extra nozzles, cables, and lances can also be very helpful. It is more efficient to have each of these accessories stored on the actual machine, rather than having to go off and find them when you need a different setting.

If you are using it for cleaning cars or other areas that will require detergent of some description, then a built in detergent tank is far more useful and efficient than a removable one. It makes the whole process a lot easier to go through as well as simpler.

The Advantages of a Commercial Pressure Washer

There are a few benefits to using a pressure washer. If you are considering buying one, here are the advantages to it:

  • Provides quick cleaning
  • It’s much more cost-effective
  • More environmentally friendly than using a hose
  • It saves you time
  • Gets rid of moss and fungi quickly
  • Can be used to wash your house or garage door
  • Can prevent the growth of harmful bacteria
  • Gives it more visual appeal

Before Using your Pressure Washer

Before you go to use your pressure washer, make sure you have read the instructions carefully and correctly assembled the machine. If using a petrol pressure washer, ensure that you have fuel and oil ready to go.

Once this is done, it might be worth having a look online for some visual guides on how to use a pressure washer if it is your first time.

An excellent example would be this quick and informative video. Once this is done and you know what to do, you can get started with cleaning the outdoor areas of your home at once.

All that’s left is to choose the perfect model of pressure washer for you. Take a look at our commercial pressure washer reviews and see which one works best for you.
