How to Choose a Karcher Pressure Washer
With all these amazing cleaning gadgets from Karcher, it’s extremely tempting to run out and buy the most powerful pressure washer in the store. Unless you plan to use the washer for light commercial or industrial use, this is usually not a good idea.
Believe it or not, pressure washers can actually have too much power, which could be dangerous to the object you’re trying to clean.
Fortunately, once you learn a few things about pressure washers, the task of deciding which one is right for you gets a whole lot easier. Let’s take a look at some of the features you’ll need to learn about before you choose a good pressure washer that will meet your cleaning needs.
PSI and GPM
You’ll hear these two terms used frequently when you’re researching pressure washers:
If you multiply the PSI by the GPM, you get the number of cleaning units, or CUs.
Using the CU number, you can more easily compare pressure washers to find the one that’s right for you. Let’s say one pressure washer has a PSI of 2,000 and a GPM of 2.0. This washer has a total of 4,000 cleaning units. So once you choose another pressure washer and do the same thing, you’ll be able to tell which one has the most power.
Karcher Gas Versus Electric Pressure Washers
Both Karcher electric and gas powered pressure washers are excellent products. Choosing between them will be the result of your personal budget and cleaning requirements.
For the most part, homeowners need electric pressure washers and nothing stronger, unless they plan to start a small business with their pressure washers. Gas-powered pressure washers generally have much more power than electric pressure washers.
They are also heavier, more expensive, and last much longer. As long as you’re just performing cleaning tasks on your deck, driveway, vehicles, and so on, you should be just fine with an electric pressure washer.
You should also take a look at the accessories available for your pressure washer. Some brands have more accessories than others, but fortunately, most pressure washers come with enough accessories to begin using them as soon as you remove them from their packaging. The additional accessories are usually items you don’t need right away. They’re just nice to have and make using your pressure washer more convenient.
Finally, pressure washers are usually divided into three categories:
Karcher are a great brand for your first pressure washer - remember, you never want to choose one that is too powerful. Just decide what types of jobs you’ll be using your pressure washer for, then research the manufacturer’s recommendations so that you get one to accommodate those needs. You can always add a more-powerful pressure washer to your collection at a later date.
