How to Choose the Best Pressure Washer
Before choosing the best pressure washer (lavadora de alta pressão) for you, it is always important to be familiar with the main features of the washers. Below, we will show the main ones:
The best type of motor is the induction motor. This type of engine is more resistant, has greater durability, powerful, and with greater pressure, but more expensive and heavier. Therefore, an induction motor is a great choice if you are looking for performance.
Unlike the induction motor, the universal motor is for those looking for value for money. This type of engine is lighter, has a higher speed, a shorter durability and less powerful, yet efficient for most domestic uses.
Maximum pressure (PSI)
Maximum pressure or PSI (translated from English, pounds per square inch), is the maximum pressure that your washing machine can exert. The higher the pressure, the more efficient it will be for cleaning stubborn dirt and other types of heavy cleaning.
The ideal is to get a pressure washer between 1600 and 1800 PSI, for domestic use. For professional use, it is recommended to take a washing machine with more than 1800 PSI.
Flow rate (l / h)
The flow rate is given by liters per hour (l / h) and is related to the pressure of the washer.
The higher the pressure of the washer, the more water per hour it will release, which is better for saving time, since you do not need to keep the washer on for a long time. This uses less water in the long run.
One thing that a lot of people are wrong when buying a washer, is to find that the washer that has more pressure, and a higher flow rate, is less economical. In practice, it works differently.
The washer with the highest pressure tends to be more economical, since you don’t have to keep the appliance on for so long to remove dirt. Thus, you save more water and more electricity.
Adjustable nozzle is a nozzle where you can switch between concentrated water jet and fan jet.
- Concentrated jet – single straight jet, ideal for washing heavier soils, such as garages and floors.
- Fan jet – spread jet to wash less resistant dirt. It is more suitable for washing more delicate objects, such as glass, cars, motorcycles, etc.
