But The Motor Works
Purchased this product in 2012 used for 2 seasons. Every piece of plastic which the water was connected to split this was not from frost seams just split on plastic pipes. Stay away from this product.

Works Great
This is my 3rd Karcher pressure washer and, like the other 3, for an 1800 PSI electric with the Dirtbuster wand, it does a super job at cleaning dirt. moss, and other misc items off cement and wood.

My only complaint on this model is the "quick connect" hose connector, since it is plastic it does not tighten well and leaks water but has no real effect on the water pressure or cleaning results.

Harold,
You may want to try fresh gaskets in your garden hose and a couple winds of teflon pipe tape (about $1 in any hardware or grocery store) around the threads. This will usually cut down on dripping.

Not A Great Machine
I bought the Karcher pressure washer mainly for cars. It has decent pressure for an electric washer. The detergent tank is small and mixes at a predetermined amount.

Overall construction is cheap, with nowhere to store the electric cord and hose. All in all it doesn't have the GPM to make car washing quick, and it's not powerful enough to do any thing else. I would spend an extra $100 and get a better unit- this one doesn't have many uses.
Mike, the Pressure Washer Expert
Product Expert
John,
The 1800 PSI should be plenty to wash cars, lawn furniture, boats, etc.

Please check to make sure your garden hose is 1/2" or 5/8" diameter, and not longer than 50 feet; and is connected to city water or a well that can supply at least 2 GPM.

If you're using an extension cord (not recommended), please make sure it is a heavy gauge (10 or 12 gauge), not a lightweight household appliance cord.

Either (or both) of these things will rob your pressure washer of power. If these solutions don't help, please feel free to contact Karcher Tech Support, toll free, at (800) 537-4129 to see if it requires warranty service. Be sure to have the serial number handy when you call.

It Works Great
I recently purchased a Karcher pressure washer and found instantly it to be defective. I called to relate my problem & was told that all I had to do was get them the serial number & model number & send that to them and they in turn would replace the washer. It was amazing

I had a new pressure washer within 3 days time- no questions asked & no extra charges. I will recommend you to everyone & by the way I love the new washer- it works great!!!

Absolutely Without Redeeming Qualities
I received it for Christmas - in Minnesota - in April. When I hooked it up to clean my boat the pressure hose blew off.

I called Karcher customer service who agreed to send me the hose; it was on back order. When I finally received it, it was the wrong hose. When I finally received the correct hose and attached it I checked all the connections and it blew off. Junk, junk, junk.
Pros: Price
Cons: Low Quality, Unreliable, Durability, Does Not Work

Brad,
If the second hose didn't attach properly either it would seem that the connector on the unit might be the issue.

You may want to call the folks at Karcher, toll free, at (800) 537-4129 to access their Factory Warranty. Please be sure to have the serial number of your unit handy when you call them.

We don't show that you purchased the unit from us by the name or email you provided, so we're sorry, we can't send over a copy of your invoice. The folks at Karcher will need one for the warranty claim.

Pump Leaking
One year after purchase, the unit is leaking. Very poor construction.
Pros: Price
Cons: Low Quality, Unreliable

Product Expert
Adi,
This unit has a 1 year Factory Warranty from the day it was delivered. Our database has no listing for you, so we're sorry; we don't know if your warranty has expired.

You may want to call the folks at Karcher directly at (800) 537-4129 if you're still within the warranty period. Please be sure to have the serial number of your unit handy when you call.

One of the things that will cause a pump to leak is not turning the unit off when you walk away. The pump uses the running water to take away the heat; if the water doesn't run, the pump overheats and leaks.

The other common reason for a pump to start leaking is storing the unit where it will freeze, and not using a pump saver product. Since you live in Florida freezing is probably not a problem for you, although if you have very hard water a pump saver product will lubricate the seals and keep them from getting crusty and leaking.

Everything Works Great, Except The Brush
So far everything works great, I especially like the rotating wand.

The rotating power brush was a big disappointment. It doesn't rotate fast enough to do much good.

Leaky Fitting
The washer worked as advertised with one issue. The quick connector on the water hose is made of plastic and leaked a large amount of water while in use. I went out and purchased a brass fitting for $6 and replaced it.

Steve,
You might also find that Teflon pipe thread tape- about a dollar at any hardware store- will do a good job stopping leaks, too.

My son in law had one and I borrowed it, I was hooked! I bought one just like it. It is the best power washer I've seen. The only thing I don't like is the hose connection should be metal, not plastic.
