Man using pressure washer

The importance of keeping your home or workplace clean at all times cannot be overemphasized. First impressions last long. This says something about how you want people to feel about you once they step into your space. However, we can’t reduce the importance of cleanliness to first impressions.

Having a clean space removes distractions, boosts your ability to focus, and motivates you to work. Not to talk about the numerous health advantages. Regular and efficient cleaning will not only keep your property clean; your property will also become more visually appealing and healthy.

Pressure washers work by adding air to the water supply to increase the speeds to provide a clean environment. This way, a pressure washer makes the most challenging cleaning tasks easy and fast. If you have found yourself having to deal with the worst cleaning jobs, pressure washers are the way to go. Still, getting the right pressure worker for your home may be a tricky business.

How To Choose a Pressure Washer

When searching for your new pressure washer, one specification you must always lookout is the pressure rating of the device. It is calculated by multiplying the PSI and GPM of the product. The result shows how efficient and effective a machine is.

Pounds Per Square Inch (PSI)

The PSI is a unit used for measuring the amount of pressure with which the device releases streams of water.

Gallons Per Minute (GPM)

This is used for measuring the volume of water released by a device in a given amount of time.

Electric Pressure Washers Vs. Gas Pressure Washers

Electric pressure washers are the ideal pressure washers for residential use doing most medium to light cleaning duties. They are usually lightweight, compact, and very easy to maneuver. They are easy to maintain, too, and they won’t require fueling or oiling. They are suitable for most home cleaning tasks. More so, you can argue that they are more environmentally friendly and they don’t make as much noise.

On the other hand, gas pressure washers are a more powerful pressure washer. They are usually more expensive and more suitable for commercial and industrial use. They have quite similar PSI ratings to residential gas pressure washers. However, their higher GPM truly sets them apart. Their ability to release a higher volume of water means they execute tasks in less time. Also, there is no restriction of movement with gas pressure washers.

Unlike electric pressure washers, once you fill the gas tank, you can get on with your job. You have to connect a power cord in electric pressure washers restrict movement even though some of them come with very long power cords. The noise gas pressure washers make; however, it is a downside. Gas pressure washers usually need more maintenance than electric washers.

Residential Pressure Washers Vs. Commercial Gas Pressure Washer

Residential pressure washers are cleaning machines that you use to perform cleaning duties inside or outside your house. So, if you need to clean your furniture, vehicles, gutter, pathways, windows, or remove some paint, a residential pressure washer is what to use. They can be either electric or gas, and they perform a range of residential cleaning duties, from heavy to medium and light duties. They are time-saving and efficient cleaners designed to tackle the toughest household cleaning project.

Compared to commercial cleaners designated for heavier tasks, residential pressure washers generally have less PSI and GPM.  Commercial gas pressure washers are designed for more professional handling and cleaning tasks. Professional pressure washers are more gas-powered than electric powered and generally have more PSI and GPM.


Generac Vs. Simpson Pressure Washer

Both brands have similar performance levels, but Simpson’s pressure washers tend to be more portable and easier to use.

Ryobi Vs. Simpson Pressure Washer

The Simpson pressure washers offer more power and durability compared to Ryobi pressure washers. Simpson pressure washers are generally preferred to Ryobi pressure washers

Ryobi Vs. GreenWorks Pressure Washer

Ryobi pressure washers are more powerful and than Greenworks pressure washers. Customers generally choose Ryobi Pressure washers over GreenWorks.

Ryobi Vs. Generac Pressure Washer

Both brands are top-rated among buyers, but the Ryobi pressure washer will take this one due to its overall performance

Karcher Vs. Ryobi Pressure Washer

Owned by Techtronic Industries, a holding company in Hong Kong, Karcher is a more reputable brand than Ryobi. While they are both popular and respected brands, Karcher offers more specialized pressure washers than Ryobi.

Karcher Vs. Simpson Pressure Washer

While Karcher may perform ideally for vehicles, Simpson is considered the best overall pressure washer brand. Simpson gas-powered pressure washers are incredibly highly rated in residential cleaning tasks. The Simpson brand makes pressure washers that are quite affordable, powerful, and more durable.

Karcher Vs. GreenWorks Pressure Washer

Greenworks makes only electric pressure washers. Karcher, on the other hand, makes both electric and gas-powered pressure washers. Greenworks is also more affordable than Karcher products. So, your choice between Karcher and Greenworks pressure washers depends on your needs and budget.


From the above comparisons, we can observe that the Simpson Pressure Washer maker stands out among the others. This is mainly because of the production of more efficient tools and incorporation of the latest technologies. Their devices are top class and edge the others in terms of high mobility, good comfort, and control.

However, the other makers also produce highly efficient tools and when purchasing one, take your time to consider the features so that you can come up with the best washer for you. The best pressure washer should leave your house completely clean.
