The Karcher K3 pressure washer is ideal for any use, as it offers professional-level cleaning, removing dirt from bicycles, fences, engines, and other items, making them shine.
Its high pressure, combined with the Quick Connect gun and the 6m hose, provide the necessary freedom of movement, while removing even the most stubborn stains. The water pressure can be adjusted with the pressure regulation gun (VPS). The turbo nozzle is ideal for removing stubborn dirt. The K3's pump is protected by a water filter - for longer life.
Quick Connect
The high-pressure hose is easy to handle, as it connects and disconnects from the device and the gun with a single movement.
Clean Tank Solution
The practical detergent container simplifies its application.
Regular storage on the hook
The large hook allows for neat storage of the cable on the device.

Plastic motor! Leakage from the motor! The components break! Failure of the entire system! Stay away, everyone! Give something more and get it with a metal engine!
Very powerful. Not suitable for professional use. I washed balcony doors and terraces with very good performance. After one hour of use, it started to heat up. It needs short breaks between uses. Pay attention to the adapter that connects to the back.
Update: I cleaned the courtyard tiles. It took me about 6 hours as my courtyard is very large. The result is quite satisfactory. I also unclogged the drain.
Small and lightweight, just as I wanted. Very user-friendly and powerful enough for the job I bought it for (washing cars and motorcycles). Also, the noise didn't seem particularly loud or annoying to me. I have used it 2-3 times so far and I am very satisfied. As for durability, I have no idea, we'll see. I didn't like the pressure hose very much. It's quite rigid, but you get used to it (can't do anything else).
I have no experience with any other pressure washer, but this one seems to have a sturdy construction and was effective in removing stubborn dirt and dust from walls and patios, making them look like new. It is also very easy to clean the car with it. However, you need to be careful when pressing the handle while opening the hose, otherwise it disconnects from the pressure that builds up. Only time will tell. I would like to have a wider variety of accessories inside the box
Recently purchased mainly for washing cars at home but also for yards. From the first use, I combined it with the Karcher 4.730-059.0 filter and I highly recommend it.
The packaging did not impress me, to be honest, and I generally expected everything inside the box to be neatly packed in bags, not loose, especially for a brand like Karcher.
The build quality is average to good, compared to Bosch of the same price, slightly better. It is very easy to assemble and there are videos on YouTube for anyone who wants to consult.
In terms of power, it is very satisfactory, better than a Nilfisk I had purchased in the same category (Nilfisk C 120.7-6 PC) and it is also much quieter. Its warranty is 2 years + 1 year if you extend the warranty on the Karcher website (a 1-minute process).
I do not have an opinion on its durability over time yet, I will come back with future updates to share my impressions with you.
11/01/2022 - Until today, absolutely no issues. It is necessary, after connecting the water hose, to perform venting (with the switch on the machine closed) and then normal use. The opposite is true before shutting down for the motor's longevity.
I have had it for 6 years with heavy use but also with a lot of care. The machine has served me well, but I also take care of it during use by taking breaks to prevent overheating, and when I finish the job, I empty the hose and the motor from the water. There have been days when I have washed 2 cars, 2 large rugs, and an 80 sqm terrace, always with breaks to prevent overheating. I believe that if you respect it, it is a good value for the money
For its price, it is a decent machine, it has a good hose length and its pressure is satisfactory for every intended use. Of course, there are plenty of videos on YouTube to see it in action.
Moderately average machine. Compared to the K7.21 (model 2007 ~ 140 bar) that I have, there is no comparison. That one, even though it's old, is a beast compared to this one. The pressure of the K3, even though it's 120 bar, is very low. It tires you out trying to remove stains and dirt. For oils and other tough dirt, it requires a lot of soaking. The build quality is mediocre. Also, the hose of the gun is quite short, to the point where it annoys you. I expected more from Karcher. This specific K3 is for extremely amateur use. Bad choice for purchase.
Excellent online store. The machine is of excellent construction and quality. Immediate telephone service from the staff. I highly recommend it for professional or household use.
After 1.5 years of use on car-terraces and rugs, the pressure suddenly dropped in the pump. It is also not easy to disconnect the hose, which is very hard and constantly twists. It also does not have a reel to collect the hose. The wheels simply do not work. I had the K2 before, which after 3 years of use, I sent to the dealership to fix it and even though I received it back okay after 3-4 months, it simply did not work properly. So, I don't plan on sending the K2 for repair because who knows when and if they will ever fix it!!! You might ask why I bought KARCHER again. I bought it because the hose for the old one that I wanted to replace cost around 70 euros. While the new K2 cost 100 euros. So, I preferred to have a new one and only use the hose and accessories that I wanted from the old one. Stay away from KARCHER now, they are expensive, difficult to use, and easily break! Just a waste of money!!! Complete disappointment...
I have it for 6 years.
I mainly wash cars. I don't put detergent in the built-in container, only in the gun making foam. Maybe this is the key to the longevity of the motor and other internal components, because I read other reviews and I see quite a few problems...
So far, absolutely no problem... maybe I'm lucky? What can I say?
It seems very powerful, I use it for washing tractors and it doesn't leave any oil anywhere, even on the engine. I washed carpets and the patio, and it even cleaned the joints between the tiles. As for the mold, it completely removed it. I don't know how long it will last, but I consider the 3-year warranty on the engine to be very good
After 1 year of sparse use without any force, it broke down. Supposedly, you give some money to get a reliable brand, but in the end, it's a total disappointment. Stay away from Karcher, never again!!
It was used for the first time in a car with very good results. It has two nozzles (one adjustable), which is very useful. The long hose also helps a lot in not moving the machine almost at all. With a retail receipt, it has a 2-year warranty, and by registering the product on the official KÄRCHER website, it adds an additional year. So the 3-year warranty is another positive aspect of the machine. As for its durability over time, I don't know yet.
*Second wash using a foam sprayer and a regular soap from jumbo. The foam had nothing to envy from professional washing as it stayed on the car and was thick, really like snow! Also, we always close the water at the end, remove the hose, and press the trigger to empty the remaining water inside the washer and clean all the accessories and the machine with a microfiber cloth. I have been following the same routine for 12 years with a KÄRCHER k2 (portable) and it still works like a charm. -24/3/21 The pressure washer still works just as satisfactorily as the first day. I don't understand how some people have them break within 6 months. Also, there is a 3-year warranty, so why "throw them in the trash"?
Unfortunately, it broke after 6 months of use. I press to spray and it doesn't build pressure. It was very powerful while it was working. It's a shame for the money we spent.
I have no opinion on its durability because I have only had it for a month and I only use it for car washing. I will definitely use it for balcony cleaning and for now, I am very satisfied. I would prefer it to come with the nozzle attachment for cleaning solution as a standard accessory. The water pressure is satisfactory for car washing and the whole machine is lightweight, user-friendly, and easy to store.
UPDATE: 2 years later and it is still functioning properly.
It broke after a few months of light use. It simply doesn't start, the on/off switch doesn't work. This is my third kärcher that breaks quickly, presenting exactly the same problem! If it cost 49 Euros, maybe it would be worth the money, but at 150-200, definitely not! Never again kärcher!
It broke after a year and very little use. I am waiting for a replacement from the dealership for 1 month. While it was working, it didn't give you the impression of the 120 bar compared to other similar ones I tried while waiting for a replacement (still waiting)
After 14 months of use, it started to leak water from the inside when I turned the switch to the "on" position. The motor was working normally but with reduced pressure. I took it to Karcher in Thessaloniki and they asked me for 69 euros to repair it. But I told them that it has a 2-year warranty and their response was that the warranty is only for 1 year from the date of purchase with an invoice!! For as long as it worked, it was average to good, but Karcher is finished for me, never again!!
I am 100% satisfied with the product... even the sound of the engine tells you that it is of good quality! Its sound is very smooth and doesn't tire me at all! If you plan to use it for a car, motorcycle, etc... and if you have the extra 20 euros... I recommend you also get the foam attachment! Washing with foam makes a big difference! I don't know about its durability in different weather conditions or if it will break quickly or cause any problems because I have only had it for a short time!
