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

Love it. Easy to use and cleans so good! Has a good power spot won’t take long to clean even your driveway. Compact and easy to store.

Nice and compact and lightweight, mounted on a shelf in my garage, and put a 150-foot hose and reel on it, It has been working great, with good pressure, not as much water flow but it is expected, overall no issues, and have used it a lot around the house (prepping roof for sealer re-coat, washing exterior walls and windows, cleaning concrete floors, washing cars, etc.) Much more practical than a gas power machine and can be moved very easily if needed, NOTE it has less power and flow than a gas-powered one but it's good for most applications without the hassle of gas and pull starting it.

needed to buy a new one. reserched around and found Karcher is still selling them--they were one of the firsts selling electric ones. this one is compact and light. does a really good job cleaning up the patio. does tasks like blasting green scrunge off of chairs and stairs. like all of these pressure washers, you need to insure there is enough FLOW of water for it to work. Initially it was stuttering, then i remembed i had my whole house water filter in the line. when i switched the whole house filter to bypass, it worked fine. despite its cheap price and small size, it MOVES A LOT of water at a pretty high pressure. Being compact, i can easily store it in the basement for the winter too! I am very happy with the investment. about the only thing i wish is that the pressure hose would be another 10 feet longer.

Went together easily enough and is well made nice brass fittings. I figured the 1800 PSI was going to be enough but it took a long time to clean the concrete patio and clean off the fountain algae build-up.

Great little electric pressure washer! Only issue I had was after about 8 months switching to a longer garden hose 50’ to 80’ and 25’ pressure washing hose to 50’ the water pressure diminished substantially and would take 30 minutes to regulate. Outside of that issue it was absolutely flawless for auto detailing. I do ceramic coatings so electric is essential as gas can strip the ceramic. Electric power washer with your canon having a 1.1 orifice installed will create the ideal consistency for automotive detailing. Compact design, light weight, and easily configurable to accommodate M22 quick release setups.

I was excited to get this Kärcher K1800PS pressure washer after reading the positive reviews. Unfortunately, right after assembling it and following the setup instructions, I encountered a major issue that prevents the washer from functioning properly. The problem is with the nozzle quick connect fitting. No matter how tightly I connect the different nozzles, there is a constant leak from this connection point when the washer is turned on. The nozzles themselves feel loose and don't seem to lock in securely even when fully inserted. I've included a video showing the leak and how the nozzles are loose even when fully inserted. You'll see water spraying out from the base of the nozzle instead of just coming out the spray tip. It's disappointing because otherwise the pressure washer seems well-built and powerful based on my initial impressions. But this leaking nozzle connection is a dealbreaker and means I'll have to return this unit for a refund or replacement. I'd recommend checking this connection point carefully if purchasing this model. Hopefully my issue was just a single defective unit, but it renders the whole thing unusable right now. I'll update if I'm able to exchange it for one that doesn't have this leaking problem.

I bought the 1800PS Cube, and it works amazingly. I've had a Karcher power washer before, but it only had the 15° nozzle. When I cleaned, I had to hold the nozzle a few inches from the ground and it tended to leave stripes everywhere. My first time using this product, I initially used only the 15° nozzle, thinking that the "Turbo" would be too powerful for cleaning my paver stones. I was wrong! What a difference! It blasted the dirt and mold away so easily, and didn't leave any streaks behind. I was done in no time. With the old pressure washer my hands and back were so sore and cramped afterward, but this one was much more user-friendly. I'm glad I got the cube instead of the wheeled version. It's easy to move around and it packs so compactly I was able to fit it right on a shelf. The only possible negative criticism would be that it doesn't have an adjustable flow. You can only control the power of the spray by how closely you are to the surface you're cleaning. For my patio I would only need a powerful spray, but if you're cleaning something that can dent, make sure to stand farther back when you first turn the hose on.

Good quality and for a good price. My only complaint is that I wish the cord/hose were longer. Overall it works as we had hoped. If you’re looking for something with the same power as gas, this is not it. However, it has ample power for washing cars, maybe just not cleaning siding on a house several feet above your head.

I only used this machine once and it does not work as it is supposed to. I wish I tried it out as soon as I bought it so I could have returned it. The "swirl motion" (not sure what its called) tip does not swirl. The machine pressures up intermittently / when it wants to. Water leaks internally and pours out the side. The wand is loose even though threaded all the way.

Buena hidro, muy practica con su cubeta para llevar todo, se escucha y se siente potente. le puse unas conexiones rapidas para poner y quitar las mangueras y todo esta funcionando bien. Viene con 3 boquillas (jabon, 40° y turbo) suficientes para el auto y casa, la mangera se dobla facilmente pero posteriormente la cambiaré por una uberflex.

I am very happy with my purchase great item

Purchased after seeing many good reviews both here and on other sites. Have to say I am incredibly disappointed. I see a lot of the reviews are a few years old so it's possible the manufacturer has changed things for the worse. The OK: So far the actual pressure washer - the unit itself - is fine. I've only used it a few times so we'll see if it holds up. The form factor is very convenient. To be completely honest, I have my doubts about how long it will last just based on the quality of the pipe fittings coming out of the plastic shell. They look extremely poorly made and if that's an indicator for the quality of the rest of the internal components, I don't have high expectations for durability. The Bad: This might be an issue with my unit specifically, but the unloader valve either doesn't work or isn't set properly, so pressure just builds up when you let go of the trigger and causes a huge kick when you press it afterwards. The pressure washer wand is the I've ever used. Worse than the cheap Simoniz ones. Way worse than the cheap Chinese drop shipped one I replaced it with. The nozzle attachments it comes with are awful. One of them broke the first time I used the machine - shot the little metal insert (not the nozzle itself, but the piece of metal inside it) out of the nozzle like a bullet. Luckily I always point at the ground when I start it. The hose is also the worst pressure washer hose I've ever had. It is comically short (a "generous" 25 feet), incredibly stiff, kinks constantly, and is altogether miserable to use. The soap dispenser on the machine is awful and inconvenient. It isn't removable, so if you do use it, you have to use all of the soap and then flush it out before you can have clean water again. The M-F filter fitting that the unit comes with is cheap plastic junk and broke on my 2nd use. This thing is probably the cause for all the complaints about leaks you see in other reviews. If you're going to buy this unit and plan to use it more than once a year, plan on also buying the following: Brass M-F fitting for the garden hose connection. Brass Quick disconnect fitting for the garden hose connection. Brass Quick disconnect fitting for the pressure hose connection. Brass Quick disconnect fitting for your wand. A new wand/gun. A new hose. A foam cannon/soap attachment for your wand. You can probably add $100-200 to the price of the unit for all of this, just to get to something you won't hate using.

Funciona perfecto 10/10
