    • Great pressure washer
Size: K1800PS Cube Color: Yellow
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.

    • Very compact and lightweight
Size: K1800PS Cube Color: Yellow
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. ... show more

    • works well
Size: K1800PS Cube Color: Yellow
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. ... show more

    • Good enough
Size: K1800PS Cube Color: Yellow
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 $

    • Leaky nozzle connection right out of the box
Size: K1800PS Cube Color: Yellow
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. ... show more

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. ... show more

    • 12 Month Review, mehhh...
Size: K1800PS Cube Color: Yellow
In my lifetime I've so far had about 5 pressure washers (currently 3 total). This Karcher is the first light duty one I purchased solely for washing cars. As of this review it's coming up on a year since I purchased it. It's not flashy, it has worked fine. I did not want an overpowering pressure washer, this one is perfect for my needs. Pressure washers have a rated life of so many hours. Models in this price range are said to have 100 hours of expected service time (you would need to spray in some Pump Guard Antifreeze after each use to help max out its longevity). If you average about 30 minutes of operating time for each wash, the expected life is 200 car washes, which doesn't seem like much especially if you have multiple vehicles, but I'm ok with that timeline. As far as the accessories don't even bother using them. The hose is only 20 feet long, so I replaced it with a non-scratching 50 footer designed for car washing. The gun is terrible, so I replaced it with a short swivel type. With all the endless options, why can't they just offer us a bare machine? The pressure washer started leaking from the machine-side (right passed the water inlet) a few days after my return window closed. The machine functions the same, but it really makes you question its viability. Overall opinion: I cannot recommend this pressure washer. At the current price of nearly two hundred dollars I find that an absurd amount for this machine (purchased mine for about half). I enjoy its small footprint, but for a machine with the same size and specs you've got to try the Ryobi from your local home improvement retailer at half the cost. If it leaks you have peace of mind with their 90-day return policy vs the 30-day here. ... show more

    • Kratcher 1800 psi electric pressure washer- great for auto detailing
Size: K1800PS Cube Color: Yellow
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. ... show more
