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.

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.

Not the most powerful. Definitely less than my gas powered 3200 psi which broke down all the time. Should be strong enough for most tasks around the house. Simplicity, lightweight and small size make it a keeper at 99 $

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.

Great pressure washer for most uses. I've used it to treat and clean my wooden deck a few times. It packs down fairly compact as well.

Purchased Aug 2025 It’s now March 2026 Worked good for a while, make sure to use water tape for leakage. Lightweight, easy to move around, long cord. The yellow tip i’ve been using for cars does okay. It’s only 1800psi so it’s not for heavy jobs. Although, It has no problem running for long periods. Recently, the yellow tip popped out as the oring had been unseated somehow inside the tip of the gun. After i popped it back in it’s been fine. Also, the handle grip has been locking up to where It’s not letting me press the trigger far enough down to spray. The side the hose connects to has a filter gasket that has been leaking, took it off and it’s fully deteriorated, I ordered a new gun and filter gasket. I hoped this would be a lasting purchase and maybe with the parts changed out it will be.

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.

Great pressure washer. Good build quality and pressure.

I am very happy with my purchase great item

Es perfecta y de tamañobideal para traer en el interior de mi carro que es pequeño. Es mejor si compras adaptadores de conexion rapida pero es perfecta, funciona muy bien. Llego en paquete sin detalles y cerrado. Para mi negocio es perfecta buena compra.

One summer, washed a couple cars and deck..put it away for winter and just brought it out. Pump ran for 15 seconds and now it's dead. Tried resetting breakers, hose plugged in, unplugged... nothing..I will be emailing Karcher about this product because I am now out a few hundred for this junk plus accessories
