Great pressure washer
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
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.

Karcher support is TERRIBLE
Worked great for a month, started leaking internally. Talked to Karcher they said they would replace it, THEY DID NOT!

Great little washer
Well, I’ll just start by saying I used to work for a big Orange hardware place as the rental manager and know the quality of this company. When this popped up on my suggested list and the price was too good to pass up, I pulled the trigger. I did purchase some extra tips with a larger orifice to lower the PSI and increase the water flow as I’ll mainly be using this to wash my cars with. The assembly was quick & easy. The usage setup is good, but I did order quick disconnects for the hoses after a few uses. The extra $20 was a smart investment. The unit is light and easy to move/use. Make sure you flush out ALL the air by pulling the trigger WITHOUT the pump being on. If you don’t, the pump can cavitate and it will surge and eventually cause damage that I believe isn’t covered. I have used this, besides washing the cars weekly, to clean thirty years of grime off the concrete driveway & sidewalks. I’ll be using it to prep the house for painting in the spring.

Good enough
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 $

works well
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.

Great for washing cars
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.

Good Power, Tiny Soap Reservoir
I'm conflicted about this little washer. There are things I like and things I don't like. I bought this to replace a Greenworks pressure washer that stopped dispensing soap, and the parts I needed to fix it aren't available. I thought about just buying a soap bomb, but I decided to get a new pressure washer instead. Amazon gave this one good reviews, although the customer reviews were mixed. The price was right, so I decided to give it a try. PROs: 1) I like the small size and shape. Since it's a cube, there are no problems with it tumping over while I'm using it. 2) Also, it has PLENTY of power for what I need, which is cleaning the little kid swimming pools I keep for my dogs, and other household items, such as floor mats and rugs. 3) It was easy to use. CONs: 1) The detergent tank is entirely too small. It holds about five minutes worth of detergent and then I have to stop and refill it. This is really annoying for me, because when I get in the mood to pressure wash, I'm washing LOTS of things. 2) It comes with a doohickey that screws into the side of the washer with a sort-of quick disconnect for the garden hose. Instead of turning the hose, you turn the doohickey to connect them, and it works well. My issue is that all my other hose accessories have real brass quick connects (male and female) that simply plug into each other. When I connected on of those to the doohickey, the hose leaked big-time. I wasn't able to screw the brass quick connect directly into the washer--maybe the threads are proprietary. I don't know. I just know I couldn't use the sort of connector I typically use. 3) It came with only one soap tip, a rotary tip, and a yellow tip. Yellow is overkill for most of what I do; I usually use a green tip. I have a set of tips, so I was able to use the green one I like, but there's no place to store them on the washer. In fact, there's no place to store all three of the tips that came with it. There are two spots to store three plugs. I watched a YouTube video of a guy setting his up. He mentioned that if you're trying to disconnect the hose to the want, you MUST let all the water pressure off first, or they won't come off. Glad I remembered that when I tried to take it apart and that hose wouldn't come off. I haven't decided whether I'll keep this or not. If I decide I need to buy a soap bomb, I might as well use the Greenworks washer I already have.

Excelente hidro, compacta y potente
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.

Garbage don't buy
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

I am very happy with my purchase great item

Decent unit, but included tools/accessories are all extremely poor quality.
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.
