Features to look out for when buying a pressure washer

There is no denying that power is one of the main features people look for when they are buying a pressure washer however, there is more to consider.


Pressure mainly depends on what you will be using the pressure washer for. If you want to remove dirt quickly and easily, the answer is simple, invest in a pressure washer that has more power. You can measure pressure in bars and the many pressure washers on the market range from 100 to 200+ bar.


There are a few pressure washers that are not exactly lightweight. Moving them around can be a chore on its own, however, investing in one that has a long hose makes life easier. Always look for a pressure washer that has a 4-meter hose and anything less than that should be sidestepped because it will just make cleaning a lot harder than it should be.

What size pressure washer do I need to clean concrete or perform various tasks?

What size pressure washer do I need to clean concrete is a question that many people ask themselves, however, before deciding on the size, you need to decide whether you want an electric or petrol one because they are different from each other. If you want a pressure washer from professional use, petrol pressure washers are the ones to go for because they have more power and designed for heavy-duty use. The best part about them is that you don’t need an electrical cord to use as they run on fuel plus they offer you extra mobility.

All you have to do is plug them into a power socket, press a button and you are ready to go. Many customers who buy electronic pressure washers love them because they are perfect for garden and home use. The major drawback, however, is the cord can make it difficult to clean or reach certain areas and it can be a trip hazard. If exposed to water and if one isn’t careful, there is the potential to get electrocuted.
