There are many traits that differentiate the varying types of pressure washers, but which type is really the ‘best’?
Is it simply the machine with the highest water pressure? Perhaps a machine with an ability to distribute hot water? Or is it the flexibility of a lightweight or petrol operation that takes the cake?
Pressure washers come in all different shapes and sizes. If you’re cleaning task takes place in the workplace a commercial pressure washer needs to be used instead of a machine designed for domestic use – this is obvious. But how does someone decipher between which commercial pressure washer to use if there are so many different types?
Firstly, you need to understand the difference between a few key metrics – for instance, comparing the benefits of cold-water machines to hot-water machines. Cold-water machines offer the benefit of maximum mobility because they are more compact, lighter in weight and certain machines can also be diesel or petrol-powered, which eliminates the need for power supply. On the contrary, hot-water machines can offer faster results and shorter drying time and offer the same cleaning effect as cold-water machines at lower working pressure, which protects fragile surfaces. In addition to this, hot-water machines have germ-reducing qualities without the need for chemicals, which is better for the environment and saves time and money and highly effective against grease, oil and stubborn dirt.
These differing benefits must be understood when you consider your own cleaning task. For example, if you’re in the construction industry you’ll likely have many varying tasks that require a pressure washer. If these tasks involve cleaning bricks and tiles, washing cement mixers and facade cleaning, then you’d likely go for a cold-water unit for the mobility it offers. If you’re looking to clean large machinery such as excavators or large vehicles like dump trucks on a regular basis then you likely won’t be moving the machine around so much – this is when you might use a hot-water unit for your site. It will differ on a case to case basis; however, these are the types of questions you need to consider when buying a commercial pressure washer.
A Kärcher rep will always have a strong grasp of the cleaning task at hand before recommending which type of pressure washer to go for. You can even request a free on-site demo or site survey before purchase. This is because we understand that there is no ‘one size fits all’ when it comes to commercial pressure cleaners. The benefits you receive from mobile petrol-powered pressure washers will be different to the benefits a hot-water unit will provide.
The considerations listed here only dip the toe in the water of what needs to be addressed before a commercial pressure washer purchase, but to answer the question of which is the best – it can be said that one must first truly define the cleaning task at hand.
