Buying Guide
When it comes to buying the best Simpson power washer, there are a few key factors to consider. We’ve used and tested several models, so we know what to look for.
Pressure
One of the most important factors to consider when choosing a power washer is the pressure it produces. The pressure is measured in PSI (pounds per square inch) and determines how forcefully the water is sprayed. For most cleaning tasks, a pressure of 2000-3000 PSI is sufficient. However, if you’re planning to clean heavy dirt or grime, you may want to consider a model with a higher pressure.
Flow Rate
Another important factor to consider is the flow rate of the power washer. The flow rate is measured in GPM (gallons per minute) and determines how much water is sprayed. A higher flow rate means you can clean larger areas more quickly. However, keep in mind that a higher flow rate also means more water usage.
Power Source
Simpson power washers can be powered by electricity or gas. Electric models are more environmentally friendly and require less maintenance, but they are also less powerful than gas models. Gas models are more powerful and can handle tougher cleaning tasks, but they are also louder and require more maintenance.
Nozzles
Finally, consider the nozzles that come with the power washer. Different nozzles are designed for different cleaning tasks, so make sure you choose a model that comes with the right nozzles for your needs. Some common nozzle types include a 0-degree nozzle for tight spots, a 15-degree nozzle for general cleaning, and a 40-degree nozzle for larger areas.
By considering these factors, you can choose the best Simpson power washer for your needs.
