DEFECTIVE POWER SUPPLY
Died after an hour of use. It worked fine for an hour the first day and the next day, I hooked up everything correctly and the machine wasn't getting any power so I surmised it was either the plug (with built-in GFI) or the switch. The problem wasn't any of my outlets. This is my THIRD Karcher electric PW and the previous ones each lasted about 3 years. The ONLY reason I bought this one was because I had previously purchased several attachments that I figured I could use again. SO, against my better judgement, I'm replacing it with the exact thing and if it dies this time, I will never purchase another Karcher product. Never.

Bought this to replace the Karcher 1650 PSI unit that I had for 8-10 years when I had a big job to do and it appear to be electrically dead.Later realized that while the ON/OFF switch no longer functioned , the unit could be run powered on/off with the GFCI control box (I donated 1650 PSI unit to our son for use at his new home and is STILL running fine, albeit with no ON/OFF switch). Now, about the K3450: Upon unpacking the new unit I immediately found it to be substantially different design. Lots of plastic parts and a piece of netting immediately puzzled me. Comparing to the 1650 PSI machine:(called '16P' hereafter) from top to bottom: 16P had a sturdy handle that came to a point on either side, like little horns. Nubs very convenient place to hang coiled up pressure hose and electrical cord, respectively.when moving or storing the washer. Current design of upright Karcher washers is u-shaped handle that comes straight across at the top, no place to 'hang' hose. Next, the 16P had a hard plastic 'hood' that snapped onto the back with two compartments, one for each wand. Very robust and convenient 'accessory'; in contrast, K3450 has a flimsy cloth/nylon net to hold the wands. I expect it to tear and be useless within a heavy usage environment.The wands catch in the netting going in and coming out. The old 16P flow control handle had a 'lock on' button that allowed you to direct the spray where needed on a long stretch without depressing the trigger, very useful on big jobs.Gone on the K3450, so hand fatigue is an issue in using the machine for extended periods. One of the worst designs I ever saw is the wheel system. On 16P it was heavy duty plastic wheels on a metal axle that passed through the washer body. The K3450 has flimsy plastic (again) wheels mounted on
individual plastic axles to be held in place with plastic studs designed to spread the wheel hub opening and 'lock' in place. They don't lock and the wheels fall off on a regular basis when moving the machine anywhere while doing a job..Now the really bad & STUPID design change: the water hose input of the 16P and quick disconnect were BRASS connections, very robust and were standard sized so readily replaced if ever needed. This is replaced by a CUSTOM sized PLASTIC connection system; my guess it will be first thing to break which will make washer useless.Karcher took a very robust friendly and serious machine design and now sells something that feels like a toy and needs 'home engineering' to make it friendly. Gets two stars only because the motor does its job of cleaning up quite nicely; the extra 150 PSI is noticeable. Wouldn't buy another one however. Better to spend more money on a sturdier/ friendly design.. ..

One tough sprayer.
Bought this to replace one that was several years old but nearly the same style, that is it has the rotating nozzle and adjustable nozzle. Years ago I read reviews that the spinning nozzle stopped working after very little use. Had the same problem. Poured about a tablespoon of OLIVE OIL into the nozzle and ran it for about a minute, then repeated for good measure. Worked four four or five years without any problem. Had the same problem with this new sprayer and fixed it with olive oil. Like new. Any vegetable oil would probably work the same.
Interesting sideline. The machine was run overnight all night, with NO water maybe three times in it's life. Turned hose on and ran like new every time. The old sprayer was left outside more than once and rained on. Eventually stopped the motor, but I have it set aside and can probably oil the motor and be back in business.

Perfect amount of pressure for the average home
Perfect amount of pressure for the average home...cleaned siding, outdoor furniture, driveway quickly and easily. We use it often. Good purchase!

Work Horse Pressure Washer
My husband and I love this pressure washer. It makes the job of getting mold off the sidewalk and the north end of the house easy!

I used it on four or five different occasions for a total of about 10 hours and then the pressure dropped to regular water pressure even though the motor was running. I tried restarting it but I couldn't get any pressure out of it.

Seems like a well made piece of equipment
Seems like a well made piece of equipment, and has worked well so far. I gave it a four instead of five because the connections for the hose are plastic and may not hold up.

Karcher continues to improve
This is my third one, and the best so far. Worked great right out of the box.
