But first, let us talk about what is an electric pressure washer and how it works.

What is an Electric Pressure Washer? 

In a scenario where you have busy timetables, cleaning your house can be exhausting and you can not afford to waste every single minute of your time. You don’t clean your houses or offices in most situations, because cleaning can take a lot of time. 

If you want to make cleaning your house simple and time-saving, you can buy an electric pressure washer for this situation. Similarly, since you can do the job in a very short time, a pressure washer will be a perfect way to clean your driveway.

How does Electric Pressure Washer Work?


First, we will talk about how an electric pressure washer works. The washer is attached to an electrical socket and then, by high-pressure water, it is used to clean surfaces. 

Pressure washers are powerful tools we experience on a daily basis, whether it is in our households or outside. We use them to quickly clean and refresh things that have gone very dirty, such as the kennel of our pet and some appliances we may not have taken out for an extended period of time for cleaning.

In a variety of commercial establishments, such as car wash shops, pressure washers are often frequently used for easier and quicker washing of the exterior of a vehicle.

It is quite easy to run pressure washers and even a first-timer will only face little or no trouble when he first picks up the hose. With their eyes closed, experienced users can also use these power tools.

One of the best and one that guarantees to be a premium electrical pressure washer is the Karcher K5 Premium and most people also seemed to agree so far. 

The question is: is it going to do all you need to do? Let’s find out about this Karcher K5 Premium Electric Pressure Washer review.

This is not a small unit, but it’s much more portable than many of its rivals. Plus, given how many washers seem to give out during the first year, the warranty is very amazing. Let’s see what it’s all about for this quiet bad guy.

Portable and Stylish


It shouldn’t take up much space for a decent pressure washer for home use. This is more important for people who have little storage space. In design, the K5 machine is compact and its vertical design makes storage simple. But because it’s high, it can be very difficult to lift it for transport.

It is also stylishly designed to appeal to the eye, with black and yellow colors. The pressure washer would also enhance your environment.

Water-Cooled Induction Motor


The type of motor the machine uses is very important when it comes to electric pressure washers. In this case, a water-cooled induction motor comes with the Karcher K5 premium pressure cleaner.

This is a very powerful and long-lasting engine that’s going to last up to 5 times longer than the normal engine. When water circulates around it, the motor works optimally and it is well regulated, thereby reducing the temperature. This boosts engine efficiency and helps it last longer.

Powerful 2000 PSI unit


When buying a pressure washer, one of the first things to look at is its strength. A maximum of 2000 PSI and 1.4 GPM is provided by the Karcher K5 premium pressure washer. This makes it offer 2800 cleaning power for such a small machine, which is cool. 

Therefore, you can clean the patio, deck, driveway, fencing, outdoor furniture, and much more using this tool. In short, it is ideal for residential cleaning activities that are light, medium, and heavy-duty.

Onboard detergent tank

It can be very difficult to use a pressure washer if it doesn’t have an onboard detergent tank. As it comes with a removable onboard detergent tank, the Karcher K5 electric pressure washer is very easy to use. 

So, without having to use another tool, the user can easily apply the detergent. Also, it has an adjustable dial that enables the user to monitor the dispensed detergent. Therefore, you won’t add excess detergent while in use.

Two wands 


Another remarkable element of the Karcher K5 pressure washer is the two shower wands that come with it. These are crucial as it allows the users to easily adjust the pressure to the best work close by. It has a Vario wand spray and a Dirtblaster splash wand. 

The Vario splash wand is for typical cleaning needs and can be adjusted to suit various cleaning necessities. The lowest pressure settings release detergent automatically. 

Then again, the Dirtblaster shower wand is made for the toughest cleaning jobs as it produces more in excess of 40% pressure than a regular garden hose. Additionally, it finishes the work in less time.
