Our old Kärcher had unfortunately broken down and had to be replaced. After much deliberation (K4 or K5 or K7 or.... too much choice ;-)) opted for the K4 Power Control Home (premium) (without the car extras because you are officially no longer allowed to clean your car in front of your home) . The Premium models have space at the back to roll up the hose, so that's why we chose this one and that is very nice when storing. In addition, this newer model is much more powerful and quieter than our old "critter". The hose and cord are reasonably long (8+5 meters, so a total of 13 meters) so that you can clean a large area without an extension cord. Because this Kärcher is stronger than our old ones, cleaning is done much faster. By the way, we cleaned our terrace without the cleaning agent and that went well. And the spray cutter from our previous Kärcher damaged our terrace tiles and while using the T5 Terrace Cleaner we had no (new) damage. In short, very happy with it, hopefully this pressure washer will last for years to come.
