A glorified squirt gun and shoots a straight stream, and this should be interchangeable with spray nozzles.

We are sorry to hear you are having problems with your Extension Wand. The Extension Wand just extends/adds on to the length of the spray lance.

The main section has the bayonet (twist and click) connector that takes the place of your spray wand. You will need to make sure you hear (or feel) the "click" to make sure it is securely seated.

Then you can choose how many sections you want to add in the middle, but you must use the piece with the spray wand receiver at the end. That will let you twist and click your spray wand (or other Karcher accessory) into the end of the extension wand, letting you reach and clean farther.

As we say in the Features for this accessory, this extension wand will only work with Karcher electric pressure washers; it will not work with any other brand.

If all the pieces are correctly connected to your Karcher spray gun you will see the full power of your pressure washer coming out of the spray wand on the end of the extension wand. If this isn't happening, please call the folks at Karcher, toll free, at (800) 537-4129 for further troubleshooting.

I live in south west Florida. We have a "cage" over our lanai that has a white frame that gets gray with mildew. The extension set I bought lets me get to the top of the frame without a ladder.

I was impressed with the quality of the extension pieces and the ease of putting them together. I would recommend it to anyone.

Beware of the plastic threads
By Robert McR. 
Lake Oswego, Oregon
Purchased 04/15/2014 | 
Review Posted 08/27/2014 
I bought this to help wash my house siding above the height that I can reach. It worked well for this.

However, I needed to break it down to store it each night and I inadvertently cross threaded the metal tube threads onto the plastic receiving threads rendering one extension tube unusable. It was awfully easy to do, so I would recommend that if you buy this not breaking it down once assembled, or at least do it very carefully.

Review Posted 08/07/2014 
I bought this extension to wash moss off my house. The added 6 feet made it easier than using and moving a ladder around.

It is a little awkward to move around being 6 feet long (plus the length of the basic gun) but that didn't matter when you see the results.

Bayonet has no pressure
By John Abrahamsson 
Coral Springs, Florida
Purchased 06/15/2014 | 
Review Posted 06/22/2014 
I purchased the bayonet extension wand for my 1600 psi to reach 2nd floor to pressure clean outside of gutters, NO pressure ! its like a garden hose but much weaker, a single skinny stream only, weak. why would you sell the bayonet with the wrong pressure tip? or tell me so I can buy the correct tip, if even available???

I will say the it works great without the bayonet, but I would not use it on driveways, you will be there all day! Great for stepping stones, walk ways, gutters, patio, stripping, entrance steps.....Stupid if anyone is using it on a car, unless you have a truck or jeep and go in the mud and or you don't care about the finish of your vehicle.

"Bayonet" is the name of the connector that electric pressure washers use. It is a 'twist and click' connection, and each manufacturer tends to use a unique profile (where the 'ears' are located) so accessories work only with that brand.

As we say in the Features for this accessory, this extension wand will only work with Karcher electric pressure washers; it will not work with any other brand. I checked our files but didn't see a listing for your pressure washer purchase, so I want to make sure you are only trying to use this with a Karcher unit.

The main section has the bayonet (twist and click) connector that takes the place of your spray wand. You will need to make sure you hear (or feel) the "click" to make sure it is securely seated.

Then you can choose how many sections you want to add in the middle, but you must use the piece with the spray wand receiver at the end. That will let you twist and click your spray wand (or other Karcher accessory) into the end of the extension wand, letting you reach and clean farther.

If all the pieces are correctly connected to your Karcher spray gun you will see the full power of your pressure washer coming out of the spray wand on the end of the extension wand. If this isn't happening, please call the folks at Karcher, toll free, at (800) 537-4129 for further troubleshooting.

The extension wand is light weight so it's easy to use- but that also means you must be careful not to lean on the wand to try and clean harder. Just let the water pressure do it's job and the wand will last a long time.

Great addition

This wand extension I bought for doing porch ceilings to get rid of bugs and spider webs. It also helps for about everything. Use in sections or at full length. It allows the electric washer much more utility.

I have a $3000 gas washer I rarely use now. This is a very good add-on product.
