Kärcher Electric Pressure Washer K1800PS, CETA Certified, 3 Spray Nozzles, Detergent Tank, for Cars, Driveways, Siding, Patios, 1.2 GPM

I bought this brand because my Mom had one and hers had broken (she had it for awhile). Read the instructions and make sure you have air out before turning it on (there's youtube videos on this) but it works really well. It's not really designed for large spaces because it will take you awhile but we did a large carport area in sections over several days and it did the job. It has 3 spray nozzles but we only used one for this particular job. The nozzle for the soap would be good for washing your car because it's not as strong a stream. There is a nozzle that makes a more concentrated stream but we didn't have use for it this time that we used it. We ran it for several hours straight with no issues. Had plenty of electrical line and plenty of hose line for what we needed to do. Easy to move around as it has wheels but we did not try and pull it around like some of those that are lower to the ground. I didn't feel like we needed to move it all that much to cover the areas we were working on. The carport was heavily covered in algae so it did take smaller stronger sprays to get the algae off. In the one area not exposed to the sun, it went much faster to get the layers of dust off and some stains. We used a degreaser (not through the detergent bin) to get some of the more heavily stained areas clean. I haven't used any other brands but I can recommend this one as being sturdy and stores super nice with everything fitting in the device itself.

This electric pressure worked flawlessly for me all summer.

Works perfectly except for the hose connector that comes with it. The hose connector is junk. It leaked and would not allow the hose to tighten on. I used the hose connector from my old karcher unit, and it worked perfectly. I don't understand why karcher makes such a good tool and then sends it with junk as hardware.

Excellent pressure washer for home use. It has plenty of power for cleaning patios, cars, and siding, and the three spray nozzles make it easy to switch between tasks. The built‑in detergent tank is very convenient and keeps everything compact and tidy, and overall the unit feels sturdy and well designed.

Amazing pressure washer for the price. I had a cheap one from Harbor Freight I got for around 80 dollars that died, but I figured I wouldn't get much life out of it so I found this one on Amazon for 129 (sale) and grabbed it. I recently just used it to clean the cars, porch, and the siding and so far it has worked out really well. It was easy to assemble, took about 5 minutes just putting the handle on, wheels, and getting all the attachments out, connected, etc. I am going to clean more of my siding in the future, but it's 90+ degrees where I live so sometimes you gotta do it later in the day or in the early morning, but all I know, is this thing works well, and I am happy with my purchase.

Needed to replace an older model that died in use. Ordered that afternoon and it came the next day. On sale at a great price and free shipping with Prime. Karcher is a great brand and it works perfectly. I only use it to clean our large screened-in lanai. My gas unit for the house is too powerful and will cut the screens. Super easy to use and brass connectors, not plastic. Great unit and has a onboard soap dispenser and nozzle too. Other accessories available. On/off foot switch. 2 yr. warranty. Highly recommend this unit.

Good morning I really don't know what to say about this product. But I was expecting the upscale product from Amazon. I ordered this back in Nov 2025. And I'm just now got time to use or assemble it to use it. Which in my book was fairly easy. But one of the things that I quickly notice was the detergent tank was not assemble. It was just sitting there. Now it's been a while since I out the machine together but I don't remember having to put the detergent tank together at any point. Anyways I went o go out it together and there's no fitting to connect the rubber hose to the tank and no prefabricated hole in the tank to connect. So now I can use this machine until I get something to connect the two. So I really can't give a review on the use of the pressure washer at this time.

The pressure washer works great but the wand snapped in half after the first use . The twist connector had to been fractured case it snapped at the connector . Now I’m using my old wand and it works again .
