Buyer’s Guide

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. 

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

Electric Pressure Washer or a Petrol Pressure Washer –  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.

Price Range – 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.

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 pressure washers model for you.

Brand – 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 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.

Key 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.

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.

Filter – These are able to protect the main mechanisms so that they are not damaged by debris when in use.

Portability – 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.

Final Thoughts

When it comes to deciding which is the best commercial pressure washers, we first look at whether you should pick petrol or electric.

Generally, the latter provides more power, but the former can be more cost-effective and eco-friendly.

A lot of it is down to personal preference. If you are looking for an electric model, the best from this selection has to be the Karcher HD511C HD5/11C 240V.

It’s lightweight, compact, and offers some incredible power levels. For petrol, it has to be the WOLF 200 BAR, 3000psi, 6.5HP.

A robust model, it offers exceptional power levels along with a great range of features that are sure to help you out while carrying out your tasks.

These commercial pressure washers are fantastic models to buy if you are looking for something reliable, durable, and powerful.
