This is the very first pressure cleaner I've ever owned. Used it a few times to clean filthy concrete, brick walls & my ute. Cleans everything brilliantly except there's a couple of issues I think should be brought to Karcher's attention & for potential future buyers:Pros:- easy to use;- manual is easy to follow, however it needs more illustrations on how to pack the unit up correctly after use.Cons:- carry handle way too short! Even though it has wheels, one still has to drag it along the ground. Needs to be a lot higher as trying to move this unit around can be quite difficult as it's heavy;- power cord isn't long enough. Need to use own extension lead.I hope my review of the K4 will assist someone in their decision to purchase/not purchase this unit.

I had a Karcher K 3 before, but it was not strong enough for my property. The K4 is much better and the right choice for my purpose. Very reliable, good features.

I grabbed this to replace a smaller unit and didn’t really know what the jet nozzle was… I love that thing! Awesome. So much faster at cleaning the muck off the driveway.I also bought the t7 cleaner head to see if that would speed things up. Previous heads that come with pressure washers have been useless so I hoped this would be good. I was not disappointed at all.As you can see from the image it’s bloody awesome.Most of the driveway that is clean is done with the jet nozzle and the T7 brush head and you can’t see where I switched.I did a three strip but on the bottom right of the photo to show how the heads works and compare.T7 is the far right right up against the fence.Jet nozzle is the middle oneSmaller left is the adjustable nozzle at full power. ... MoreI grabbed this to replace a smaller unit and didn’t really know what the jet nozzle was… I love that thing!

Bought this to replace the previous model of this unit, and the new one is faulty straight out of the box - the garden hose blows off at the unit when I release . Good service from Supercheap, but sub par crap from Karcher. Never again. The marketing for this unit is all lies, they give the impression that you can select the pressure through three buttons on the handle, not true - they are indicator LEDs.
Poor build quality for the price. Nozzle not working already, seems to have some sort of blockage. There was also a crack on storage compartment.
Easy to put together, (If you’re not keen on reading instructions, search for your model on YouTube and there are plenty of unboxing/setting up videos that make it a breeze!). Pressure is perfect, cleaned up and old ‘breeze block’ wall from dirty green/black to looking new! Easy to use. Very happy with purchase.
Bought me k4 only a month ago and has been fantastic. Previously had a k2 and must say moving up to the k4 has been great with the extra 500psi and the simplicity in its design makes it easier to move around.Extra 6m in the high pressure hose and been on a reel is great. Highly recommended.
Only used a couple of times but awesome product and very easy to use. Have cleaned car and back patio. Worked perfectly. If you want one to just be cleaning walls and concrete only, I would buy a stronger one as it will save a little bit of time but this is perfect for all purposes.
Having previously only used a heavy duty commercial waterblaster associated with my workplace, I was initially somewhat sceptical about how effective a plastic looking light duty machine would be. After checking various reviews I decided on the Karcher K4 and to be honest, it compared very favourably to what I had been used to and I was not disappointed in the K4s performance. I like the portability of this machine and is powerful enough for many tasks around the home including stripping flaking paint from a fence prior to painting and cleaning mould a gunk from masony. So far very impressed and highly recommended.
Fantastic Unit, very powerful and great for both home use and professional use.Easy to move around. A worthwhile product to purchase, especially for home use.
