Karcher K7 Premium Full Control Pressure Washer Review

This Karcher K7 Premium Full control home pressure washer is the latest model from Karcher. This is the highest performance pressure washer in the Karcher range and one of the most powerful pressure washers on the market. This is the update to the previous K7 model featuring a new design and high performance.  

Here are the specs for the K7 Premium full control pressure washer:

FeatureSpec
Waterflow (l/h)600
Pressure (Bar)160Motor (watts)2800
Pressure (Bar)160Motor (watts)2800
Hose Length10m

Equipped with a 10 metre high pressure hose, cleaning around cars and vans is easy without having to move the base unit too often. This hose is easy to pull out and put away, as well as storage on the front of the K7 for easy storage of the trigger gun and lance. The unit is robust at 18kg and will take some lifting which is aided by the handle on the top of the unit. You can also easily move the unit on the ground thanks to the durable wheels. The simple yet sleek design adds to the overall quality build of this pressure washer. 

The K7 Premium Full Control comes with a number of accessories included to help make your cleaning more efficient and quicker. 

  1.  3 in 1 multi jet vario lance

    This multi-jet lance helps you to quickly switch between different types of spray, by twisting the head of the lance. You have 3 options to use depending on the pressure required. Standard flat jet nozzle, detergent dispenser and dirt grinding nozzle. By increasing the pressure like this not only do you save time by not constantly finding and changing to the correct accessory, but you can make sure you do not damage your property. When cleaning a car for instance it is best to use the finer spray and then increase the pressure when moving to your patio for more stubborn dirt and stains.

  2. Dirt Blaster Spray Lance
    When you need a bit more power to get rid of tough stains and dirt then the dirt blaster is for you. Ideal for patios and other surfaces exposed to the elements, the blaster produces a high pressure rotating point jet which can help to clean these areas.

  3.  T450 Patio Cleaner
    One of the most common uses for the Karcher K7 Premium pressure washer is for cleaning patios. The T450 attachment helps you get your patio looking like new while saving you time. It is a powerful attachment which gets great results. However, if you are working on more delicate surfaces you may want to lower the pressure, which can be done at the flick of a switch. Because of the protective grille you can also use this attachment to clean over gravel and other lose surfaces.
  4. 10m high pressure hose
    The 10m hose ensures that you can reach around large vehicles and hard to reach areas without constantly moving the base unit. 

Pros

  •  Suitable for cleaning a variety of items
  •  Powerful pressure washer
  •  Excellent for patio cleaning
  • Attachments save time
  • 5 Year manufacturer warranty

Cons

  • Can damage delicate surfaces

Pressure Washer Guide

What Are Pressure Washers?

Pressure washers offer users the chance to clean their property using high powered, motor assisted water compression. These are usually electric powered for non-commercial use but can also be petrol powered. They are usually attached to a standard garden hose and so are simple to use and set up. 

In order to clean touch stains and dirt, they use a focused stream of water which is highly powered out of a nozzle. This saves time and elbow grease over the alternative of a hard scrub.

What Can I Clean With a Pressure Washer?

There are a lot of items around and attached to your home which a pressure washer can be used to clean. Be careful to check which pressure washer is suitable for the area you wish to clean before starting, as some washer models are more suitable for different jobs than others. For instance a long hose is very useful for getting around a large van without having to move the base unit. However, you may require less pressure for more delicate areas.

Areas which a pressure washer can be used to clean:

  • Cars & Vans
  • Bikes
  • Patios
  • Garages
  • Outdoor Furnitures
  • Brick/Stone Walls
  • Driveways
  • Many many others…
