Choosing The Best Pressure Washer

You likely know what a pressure washer is and what it is used for. That doesn’t mean you’ll know what to look for if you want to purchase one. Pressure washers aren’t all the same. Like many consumer products, there are features that can make some pressure washers better than others. When you know what those are, it’s easier to shop for the best pressure washer for your needs.


Here are some important factors for choosing the best electric pressure washer.

  • Cleaning power rating (CU-cleaning units)
  • Pressure (PSI-pounds per square inch)
  • Flow rate (GPM-gallons per minute)
  • Size and weight
  • Quality of materials
  • Motor and pump
  • Accessories
  • Price

You want to compare these against each other when you’re looking at different models of electric pressure washers. Once you know what to look for, it will be much easier to choose the pressure washer for your household. That being said, let’s start by looking more closely at the factors listed above. Then we’ll show you some specific models for sale on Amazon right now that may make good options for your needs. 


What Should I Look For When Buying An Electric Pressure Washer?

Some manufacturers are very clear about what the cleaning power rating is for their products. It’s sometimes indicated as CU, or cleaning units, within the product description or somewhere on the box. That rating is a function of the pressure and the flow rate. The pressure washers have a high cleaning power rating. But what does that actually mean?

Sometimes you’ll have to calculate the cleaning power rating on your own. You’ll do that by multiplying the pressure and the flow rate together. The pressure is measured in pounds per square inch (PSI) and has to do with the force that is being created to push the flow of water through the hose. The flow rate is measured in gallons per minute (GPM) and indicates the amount of water that can make it through the hose every minute. You want both of these numbers to be higher for the best pressure washer. 

What’s More Important In A Pressure Washer—PSI Or GPM?

Neither of these is more important than the other. You can have the best pressure out there, but if the flow rate is low and slow, it won’t matter. The water stream will be too small to make much of an impact. Cleaning will take you a lot longer this way. The same is true the other way around. If you have a high flow rate, but your PSI is low, there won’t be enough force to push the flow of water very hard. That will make it hard to clean some types of dirt and grime off of certain surfaces. It makes for weak pressure washers. 

Should I Buy A Gas Or Electric Power Washer?

There are a lot of reasons to buy an electric pressure washer to use at home. Two of the most important reasons, though, are the size and the weight of electric pressure washers compared to the size and weight of gas pressure washers. You’ll find that gas pressure washers are built more for commercial use rather than residential use. 

Most of the pressure washing projects you’ll be doing around your home won’t require any more power than what you can get from electric pressure washers. So, you don’t need something with a huge and noisy motor inside that is fueled from a large gas tank. Gas pressure washers have additional components that cause them to have to be larger. Not only does that make them harder to maneuver around when you’re performing your cleaning tasks, it makes them hard to store, too. 

The size isn’t the only problem that extra components present. There is also the matter of how much many gas pressure washers weigh. A gas pressure washer that is heavy can make your cleaning sessions very tiresome and even dangerous, in some instances. 

Residential consumers also like that electric pressure washers are quieter than gas pressure washers. They’re better for the environment, as well. 


Other Considerations For Choosing The Best Pressure Washer

Most electric pressure washers are made of plastic and PVC hoses. You should take a look at the build of the electric pressure washer you’re considering. It’s ok for them to be made of plastic, as long as its thick enough to support the activity and well built. 

You’ll want to look at the fittings and what they’re made of. Manufacturers will often scrimp on the materials for the fittings in electric pressure washers. They will use plastic fittings that leak and break easily. The best pressure washer options will have brass fittings or something equally durable.

The motor and the pump are the components that are going to back up the PSI and GPM to get you that high cleaning power rating. Check that the motor is working with at least 12 to 14 amps. That’s about where you’ll want it for an electric pressure washer to use at home. Be careful with going higher than that because it can result in blown fuses.

The pump will either be axial or triplex in design. Axial pumps are larger and won’t be as efficient as triplex pumps. There will be a slightly higher cost associated with electric pressure washers that have triplex pumps, but it’s worth it for the smaller machine and increased efficiency.

If you’re really having a tough time choosing between different electric pressure washer models, you can turn to the accessories that are included. The best pressure washer options will have multiple nozzles that are interchangeable. A longer hose is ideal to give you more range. An extension cord will help with this, too. Also, look for the storage piece for the cord and the hose. You can even find electric pressure washers that have an attachable reservoir for detergent to use in the spray or an intake hose that draws soap in.

You need to make sure you are comparing the prices of different electric pressure washers, as well. All features being equal, choose the best pressure washer price.
