Q: I want a Karcher Pressure Washer with a built-in detergent tank-no siphoning. Is the Model K2.425 my only choice? I will be using the unit for general exterior house cleaning,etc. No commercial work.
by Arnold on February 25, 2012

A: No, there are a few models that Karcher offers with a detergent tank or bottle. Along with this model, models K3.48M, K3.740, & K5.740 have either a detergent tank or bottle built into the machine.

Q: I need to pwer wash brick, cinder block, and blue slate at my home. Which power washer will get the job done?
by Reese from New York on June 27, 2011

A: Something lik this would do the job, as long as this is just a cleaning and not a deep clean or resurface. It is most likely going to take you a while to do this, but would should do the job. You may want to bump up to something a little more powerful though to cut down your cleaning time and make everything easier.

Q: Comparing the different Karcher models, I still have the same 2 basic questions.1) Does motor shut off with the trigger wand? and 2) where the water hose connects is it metal or plastic and is a kit needed to covert it to metal?
by Judy Averhart from Mississippi on March 27, 2011

A: Yes all Karcher electric models have the total stop feature when you release the trigger gun. Some of the Karcher models have brass water inlet fittings and some models have plastic. This specific model has plastic garden hose fittings and comes with a plastic quick connect attachment to prevent the user from cross threading the threads. To convert the fittings to plastic, you would have to purchase a brass garden hose quick connect kit.

I posted the product below that I am referring to:

Q: Do you have any self priming pressure washers for sale (gas or electric) ? I have wood deck on my 1/2 acre pond to clean & would like to be able to use the pond water. Thankyou.
by John from Ohio on March 25, 2011

A: Yes, all Karcher branded pressure washers both the gas and electric versions have self priming pumps that can pull water from a standing source such as a tank or pond. We also sell Kranzle and DirtKiller brand pressure washers which too have self priming pumps. Kranzle and DirtKiller only offer professional grade pressure washers while Karcher offers residential and prosumer grade models.

I would definitely recommend that you use a filter on the end of the hose that is placed in the pond to prevent debris from entering the pump. Karcher makes a hose with filter for this purpose that we sell as an accessory.
by Brian, Product Expert

Q: What happens when you use hot water in a Karcher electric power washer? I never knew they were (Electric-Cold Water) listed.
by Bob Mills from Michigan on March 25, 2011

A: Karcher's cold water pressure washers can accept water up to 104F degrees. This is common with all cold water pressure washers. Using water hotter than 104F degrees in a cold water pressure washer will definitely damage and wear away the seals in the pump, causing the pump to fail. This is the fastest way to damage a pump that is rated for "cold water".
by Brian, Product Expert

Q: Just bought the Karcher 3.74 from you guys. What is the "Pump Guard" which is recommended for storing and protecting the pump? And how do I use such?
by Preben Jensen from California on March 24, 2011

A: The Karcher pump guard is a chemical that is designed to extend the life of the pump and the seals within. Pump guard or pump saver as it is also called, will lubricate the seals in the pump and also prevent any water that is left inside the pump from freezing during the colder months.

To use this product, you simply attach it to your garden hose water inlet fitting and turn the machine on for a few seconds. Once the chemical exits the outlet high pressure fitting, the pump is protected.

You should defintely run this chemical through the pump every time you are going to store your pressure washer away for extended periods of time such as over 30 days. You should also run this chemical through the pump periodically throughout the year to keep the seals moist.

Need To Wash Underside Of Car
Here in mid-coast Maine, we get a lot of salt spray and consequent corrosion on the underside of vehicles. I have a model K3.97, 1600 PSI Karcher that has served me well for 6 years.

Is there an adapter available to allow me to spray (up) to wash underneath the car? It would need an angled output nozzle.

Karcher actually makes two for their electric washers.

The simple Underbody & Gutter Cleaning Angled Wand is a useful tool around the house as well as cleaning your car.

If you're serious about cleaning under things (and it sounds like you are!) then Karcher also makes the very cool Chassis & Underbody Surface Cleaner. It fits all current Karcher electric pressure washers K2 thru K7 with a set of color-coded adapters.

It rolls easily to clean where you can't reach, and has a foamer attachment so you can soap away grime and salt. Pleae be aware that your vehicle must have at least 6" of ground clearance for this accessory.

Cheap, Did Not Work
Water came out of the nozzle but with minimal pressure. Very cheaply made. It is not Pressure Washers Direct fault but for the price I would expect quite a bit more quality. It would be nice if it worked out of the box.

Sending it back. Hopefully I get a full refund.

I looked for your order; it was under a different email address. We used that other email address on 4/21 to send you instructions on what was needed for your refund. If you haven't received the instructions yet, please check your Junk Mail file; sometimes they wind up there.

The "X" series pressure washers have sold well, and our customers have been very pleased with their performance. I'm sorry this wasn't true in your case. We appreciate your business, and apologize for any inconvenience.

Approved By A Couple Of Oldies
We are a couple in our 80's living in a wooded area. Our sidewalks get black. This machine cleaned the walks faster than any other machine in the past. They actually look like new.

We found it easy to use for folks in our age bracket. We did have to add extra washers where the hose attached, but once that was done it worked with no problems.

Finding it so easy to use, we ordered the gutter cleaning attachment which we plan to use next spring. Thanks for a nice piece of equipment.
Pros: Easy To Store, Easy To Use, Light Weight, High Quality

Big Disappointment
My wife bought me this thing and was so proud of herself for getting me a much needed tool. I don't have the heart to tell her that it works better as a boat anchor than a tool. Total junk.

The veri-wand worked for maybe 5 times before breaking. The internal plastic connectors from hose to motor broke. It sprays water from the inside of the housing. A one year warranty is great except it seems the parts are designed to break in 13 months. Worst power tool I ever had.
Cons: Low Quality, Difficult To Use, Unreliable, Durability

Worst Power Washer
If I hadn't throw away the box I would have return it. I had to use vise grip to try and stop it from leaking water everywhere and could not.

Very, very disappointed after seeing your info commercial.

A few wraps of Teflon pipe tape (under $1 at any hardware or grocery store) on the threads can help reduce leaking where the garden hose connects; so can adding a fresh garden hose gasket (about 25). Please be careful with the vise grips- adding a garden hose quick connect set ($5 at home stores) will save wear & tear on the plastic connector.

If those tips don't help- even though you've thrown away your packaging the warranty on the unit is still in force. Karcher's Rapid Exchange Program will replace your pressure washer with very little effort on your part- just click on the link to see their explanation on how their program works.

You will need to send Karcher a copy of your invoice. Please just click on the "My Account" link in the upper right corner of our website and follow the prompts to print one out.

I'd also like let you know Karcher makes all their own info commercials & advertising- we are allowed to use them on our website, but we don't have any say on their content.

We appreciate your business, and I hope I've been able to help!

Very Light Weight And Quiet
I use a washer a lot and the last one lasted about 10 years- same brand, different model. There are a few changes to this one for the better, much quieter and lighter.

Great product for the money.
Pros: Light Weight, Easy To Use, Quiet, Price

Electric Pressure Washer
Once I determined that this unit would not pump water from the lake and hooked it up directly to our well, the unit worked fine. It might be a little under powered for my use, cleaning a wood deck of three years of dirt and algae that results from living within thirty feet of a lake and a little more power would have helped. But the electric unit worked just as well as the gas unit I previously used, except that its range is limited by its power cord. There were no leaks whatsoever, and the... more

Did Very Well
My main use is for landscaping blocks. What made me decide on this model was the rotating nozzle.

I needed power enough to take off moss, residue and ground in dirt. This model has done just that. I was disappointed about the water leak spray I get from the hose connection. Tried three different connections and no luck. It does not take away from the performance, its just annoying.

Just cleaned over 200 blocks, did very well.

Not A Pressure Washer
I purchased this 1600 psi unit to replace a 1500 psi unit that I have used for 12 years. There is no adjustment to the spray that will maintain any pressure to clean a surface. I was trying to clean my garage floor not very productive with a 2 inch wide spray!
Pros: Easy To Use, Light Weight, Easy To Store
Cons: Low Quality

This pressure washer includes both Vario-Spray Wand and a Dirtblaster Turbo Wand. I would suggest reviewing the Owner's Manual to make sure you've assembled it correctly and are using it correctly. If you're still having issues, Karcher can be contacted directly @ (800) 537-4129
