Questions & Answers


I have no exterior outlets. can I use an extension cord with this power washer?

Asked by Gail May 16, 2020

Check the outlet your plugging into for proper wiring.

My plug keeps clicking and resetting itself and when I push the test button, the light stays on. What to do now?

Asked by Karcher April 22, 2020

Sounds like a defective GFCI. Return it.

Are they seriously requiring you to disconnect the hose from both the unit and the handle, coilin...

Asked by Joe April 21, 2020

The hose is an uncooperative “roll up” option, so I guess disconnecting it will help store it. More importantly though, the spray gun developed a major leak after just some limited household use. Water is streaming out under the threaded area where the hose attaches, making the whole unit useless. BUYER BEWARE! Thing is junk

Does the detergent concentrate need to be diluted before pouring into the tank ?

Asked by Supertool January 23, 2020

Concentrate means that it is in a form with less or no water, meaning you will have to dilute it and sure it’s fully homogeneous before using. So probably best to do mixing in a separate contained in whatever ratio required before pouring in.

What are maximum and minimum water supply hoses that can be used and can a quick release be uses ...

Asked by Jack August 21, 2019

Standard 3/4 inch garden hose is recommend, I use a quick connect with no adverse effects.

It has three tips.... what are they in degrees? 15, 20 40 ??

Asked by richard March 15, 2019

15, turbo, and detergent spray.

Asked by Sarah August 5, 2018

I want to clean my travel trailer. Is this washer the one I want or should I purchase a lower PSI?

Asked by BK July 3, 2018

Dear Home Depot Customer, this pressure washer (or the K3 Follow Me) would be great for cleaning your travel trailer. Always start with the lowest pressure and then move up as needed. Hope this helps! Karl, Karcher Customer Care Team

Full disclosure, I have never used a pressure washer before now. But it is awesome! Cleans so well, and saved me so much time! Assembly took just a few minutes, and because it is electric there is no need to fumble with mixing oil or running to the gas station. Plug it in and let it rip. The machine is relatively light, but has wheels anyway to make moving it a little easier. The wheels are big, which allowed me to easily roll it on grass. There are three nozzles, one specific for soap (although I have not tried it with soap as of yet). I got the washer to clean the vinyl siding, particularly in places a regular hose couldn't reach. But when I used it on my composite deck (picture below) I realized just how much I needed it. Last year I used a scrub brush, literally on my hands and knees and it did not come this clean. And this was without any detergent - just the high pressure spray (which is great because then it won't harm the surrounding plants). I also realized it works great to clean the white railings, which I also have cleaned painfully by hand in year's past. The washer literally saved me hours of work - and that's just on the deck!

looks to be a heavy duty outfit
Things do get dirty, It is a fact of life. We had to replace our pressure washer and this one became available so we got it. It looks to be a good solid outfit. I like the foot switch for turning it off and on when. When you have your hands full it is very handy. I like the brass hose fittings which I believe will prove to be very durable. I like the large detergent reservoir with a big easy to hit screw top for no slop. I really like the on board bin for storing the nozzle and hose when the unit is not in use. I really think this machine will serve me well for a long time.

Makes cleaning easier
This is a great pressure washer. 3 different nozzles to regulate the amount of water pressure so you don't damage anything with too much water pressure. Cleaned these concrete scalloped edgings very quickly. It has a ground fault in the plug. Playing with water and electric, you need a ground fault. I wish the cord was a little longer. Electric outlets on the outside of the house are farther between. One thing that the manual does not show is how the connector goes on the machine. The silver side goes on the machine and the black side goes on the hose.

Easy Assembly; Great Pressure; Excellent Cabling/Hose Lengths; Full of Features!
This pressure washer is well-designed, and it was extremely easy to assemble! The handle just unfolds. The wheels went on very smoothly. The hose for the wand has the same fittings on both ends so no confusion over what attaches where. It could not be easier. Most fittings (see pictures) are brass so no issues with corrosion in the future. The power cord is about 35 feet in length and has a built-in GFI for safety (see picture). The power cord easily stores on the handle (see picture). The hose for the wand is about 20 feet in length, so you really have a great amount of flexibility in where you can go with it. You have a choice of three nozzles (soap, 15 degrees, and "turbo")(see pictures) and they store on a horizontal crossbar near the top of the handle so they are easy to reach. They also solidly plug into their respective sockets so there is little chance of them getting lost. Karcher really put some thought into the design of this pressure washer. The wand hose is rated for 2,000 PSI (see picture), so it will easily take the 1,800 PSI that the unit produces. You seldom see a product like this where parts have such excellent safety margins! Lastly, the three-year warranty gives me confidence that this pressure washer will give me many years of trouble-free use. I highly recommend this pressure washer for most any cleaning jobs around the house. This is a really good performer!

After having another brand pressure washer around the $120 range from Home Depot I decided to spend a little extra on this unit. It seemed like a high quality unit out of the box but after using it you find this is not the case. During my time using it initially there was poor craftsmanship with the nozzle not fitting properly into the wand. I used this unit maybe 2-3 times before putting it away for the winter, which it was stored in a basement. After our first nice weekend here in the northeast I decided to power wash the truck. First the unit would not turn on. Secondly, the connections at the hose leaked at the wand and at the unit itself, leaving the unit with very little pressure. It seemed like a great unit, maybe I just got one of the bad ones. It's very frustrating to spend $180 on a unit that works great the first few times then has nothing but issues. Pros: Great storage Onboard soap On/Off foot pedal Cons: Poor construction Leakage

This pressure washer is for light duty projects only. I tried it on several tasks and compared it to a gas powered, higher pressure washer. Dirt that the Karcher couldn't remove point blank the gas washer removed at over 6 inches. Both the online purchase and the "hastle free" return at HD were flawless...

Quick and easy to assemble although the instructions aren’t that great. Used it (without detergent) and it worked well. Stronger than the 15 year old Karcher that finally gave out. I like the different nozzles. And the long cord. Good purchase.
