Premium K5 Karcher Pressure Washer Review

Kärcher K5 Premium

If you’re looking for a pressure washer where there are no compromises, with power to spare, then the K5 Karcher Pressure Washer might just pique your interest.

It’s the second most powerful model in the Karcher Full Control range, and it offers excellent power with great cleaning delivery.

Like the other models in the series, it has a full set of accessories for domestic cleaning tasks, and it even has some advanced control technology built right into the lance handle.

If you need a unit that can deal with almost every conceivable cleaning job, then it’s time to take a closer look at the K5.

Karcher K5 Premium Features

  • 145 bar pressure with 500 litres per hour of water flow.
  • Includes an 8m high quality hose.
  • Integrated hose reel and on-board lance clip.
  • Pressure controls built into the lance handle.
  • Water cooled motor.
  • Plug-in detergent system.

Who Could Use the K5 Karcher Pressure Washer?

The K5 has been designed for the most demanding domestic users. 145 bar of pressure is a significant increase over the 110 – 130 bar that is found in most entry to mid-range units.

More pressure means better cleaning, and the high water flow rate means that cleaning is faster. If you need to clean your car, even if it’s an off road vehicle, then this would be an ideal pressure washer for you.

The unit will also clean outside surfaces, including patios and decking, and it can be used to clean fences, walls, garage exteriors, and house exteriors.

If you have any outdoor cleaning task, ranging from garden tools to outdoor furniture, then the K5 Karcher Pressure Washer has been designed for you.

Cleaning Performance

As a high end model, you would naturally expect the cleaning performance on the Karcher K5 to be nothing short of excellent. If you do decide to purchase one of these, then you’re not going to be disappointed, and your expectations may even be exceeded.

The high pressure and water flow both mean that not only can you tackle everyday cleaning tasks, but you’ll also be able to clean heavily soiled surfaces, even those that have been neglected for years.

Clearing debris out of brick or stonework will be easy with the 145 bar pressure, and light-duty tasks will be over in minutes. If you’re cleaning a city a car, you’ll be able to complete the job with fewer and faster passes of the lance.

Even if you own an off-road vehicle that you’ve taken out for some fun on the weekend, the Karcher K5 Premium will be perfect for getting out mud and any other debris that you’ve picked up along the way.

If you have used other pressure washers that have felt underpowered for your needs, particularly entry level models, then the K5 Karcher Pressure Washer will be a noticeable step up, that will likely satisfy all of your cleaning demands today, and in the long term.

Included Accessories

If you’re familiar with other Karcher pressure washers, then you will know that they come with all of the accessories that you’ll need to start cleaning various surfaces and items at home.

The K5 has a multijet lance that is an improvement over the individual lances that they provide on older and lower tier models. This attachment can be used for basic pressure washing, dirt blasting, or applying detergent to a surface before hosing it down.

This model also includes the T350 surface cleaner, which allows you to clean horizontal and vertical flat surfaces without excess water splash.

There’s a detergent plug-in system that is easy to use, and is a big improvement over the suction hose attachments on entry level models.

One of the best features on this premium model is the addition of the Full Control system. It allows for pressure to be adjusted with an electronic keypad, and there’s also an LCD display to show you the setting that is currently selected.

Best and Worst of the K5 Karcher Pressure Washer

This high end pressure washer doesn’t disappoint when it comes to features and performance. Some of the highlights are:

  • Easy control of power modes from the lance grip.
  • No need for multiple attachments, thanks to the 3-in-1 lance.
  • Excellent power and water flow makes heavy cleaning jobs easy with this pressure washer.
  • Water cooled motor allows long operating cycles.
  • 3-year warranty provides peace of mind.
  • Included patio and flat surface cleaner head.

There’s nothing particularly disappointing about this pressure washer, and besides bumping the power, there’s little room for improvement. While you may see the high price as a downside, the fact that it comes with an extensive warranty and is incredibly well made, means that the investment will continue to pay off for years to come.

Final Thoughts

This is a pressure washer for people who have extensive cleaning tasks, with some of them being particularly grimy or heavy-duty. It’s not an entry level unit and isn’t the best option if you only plan to clean your car and driveway every other weekend.

However, if you do need the power that comes from high pressure and increased water flow, then you’ll find a lot to love about the K5 Karcher Pressure Washer, and the extra touches like the full control lance make this a compelling choice in the high end market.
