## Description

The Kärcher FJ6 foam nozzle provides a powerful foaming action for easy vehicle cleaning. It can also be used to clean garden furniture, siding, stairways, RV's, paths, walls, patios, driveways, etc. The FJ6 container holds approximately 20 ounces. To use the Kärcher FJ6, simply pour Kärcher detergent directly into the foam nozzle, add water (if using concentrated detergent), attach the nozzle to your pressure washer gun and apply the foam. The detergent Dose can be easily adjusted on the foam nozzle using the yellow dial on top. The jet level can be easily adjusted as required. The FJ6 foam nozzle is compatible with all Kärcher K2-K5 pressure washers. Not compatible with K1700-K2000 power washers or gas pressure washers.

Review: Nice Foam Attachment for my intended use.. car wash / detailing - For use only with Karcher Electric Pressure Washers as it attaches with the proprietary Karcher wand connection. Works quite well for foaming a car when washing. You can adjust the amount of the mixture and adjust the direction of the spray path with the twist of a nozzle. Background on my primary use of the product - I much prefer an electric pressure washer to a gas as there is less noise and fumes plus they are typically more cost efficient to purchase and run. I use mine primarily for detailing my cars and some occasional cleaning of plastic siding on the house, so anything over 2000 PSI would be over kill for my purposes. The use of the electric Karcher also allows me to wash my cars in the garage with the door closed during the colder months and out of the sun during the summer months. Review of the actual product - In terms of this Foam Jet attachment, most Foam Canons are only made to use with gas pressure washers so this was a nice find for the electric Karcher models. In terms of operation and results, a proper Foam Canon such as MTM creates better foam but this is a close second having used both. Considering that MTM and others require the use of a gas pressure washer and these Foam Cannon's cost roughly twice as much as this Karcher attachment, this is a great product. It is also far superior than trying to use a Foam Sprayer that connects to a regular garden hose or the regular reservoir that is attached to most electric Karcher pressure washers. I purchased this model as it appeared to be better when compared to the smaller Karcher model 2.643-146.0 since it has a larger reservoir as well as the ability to change the mixture (density of foam) with the turn of a knob. The smaller version had many reviews that were also complimentary with most of the complaints centering around the size of the reservoir and this one again has a larger capacity. At the date of my purchase the model as reviewed is also only about $10 more than the smaller model. You can also do a search on youtube for Karcher Foam Canon and see videos of both this and the smaller model in action.
Review: perfectly match for my karcher k2 - great material, working perflectly
