Kärcher FJ10 Foam Nozzle with Ultra Pressure Washer Detergent

Great product I was a little u sure when buying it but I read the reviews which is what sold me on the item. I run a K4 I bought the ultra foam over and above the car shampoo it gave me a great foam I've just done 4 cars and could probably do another 8 of 1 bottle so that's really good value for money. The click system is so easy to use and the bottle can be refilled after. The actual ultra foam is really good and I have a great finish so I'm tempted to just try and get a refill of that but the option is there if you want to use a different one. Personally for the money I'd buy this one over and above a generic one.

This Karcher FJ10 nozzle is brilliant. Twist lock onto the Karcher handle - Click fit to the bottle of foam wash that was supplied with the nozzle and turned the mix ratio dial down to minimum... to test the foam-ability of the combination. I was highly impressed even with the dial set to minimum.... the car was covered in a thick blanket of foam. My car is a large 4 door saloon and has a large surface area to cover. But I reckon I only used about 1/8th ( 12.5% ) of the shampoo, so I think I will get 8 washes out of the 1 bottle of Karcher Car foam. So that's not bad value when you think about it. You can then either purchase more Karcher or refill the empty reusable bottle with the foam of your choice. I am very happy with the quality of the Karcher nozzle and can genuinely recommend this model when used with the K4. The foam is great on bodywork and washed off lovely, however I prefer to use an alloy wheel cleaner specially formulated to dissolve break dust to keep my alloys in tip top condition... each to their own... I guess..... but just be aware that the Karcher foam wash has it's limitations.... don't hesitate if thinking about getting one, I'm sure you'll be as happy as I am with my purchase.

The product works very well, I like the flow rate adjuster, so I'm not wasting too much of my products, the quick release system is also brilliant for quickly switching between pre wash, shampoos and car wax. The main reason it is a 7 is because of the relatively cheap feeling construction combined with the price tag, that I feel is a little steep. Maybe have a version where you don't include the karcher shampoo too lower the price for those that have their own

Good job but very hard to insert and remove from the lance

Really enjoy using this foam gun, when the car is white over, leave it for 5 minutes to allow the foam to dissolve the dirt, jet wash off and apply remainder of foam, wash with soft brush or microfibre cloth, wash off and wipe dry with clean microfibre cloths. Brilliant 👌

I've previously purchased a snow form lance from a leading car detailing website, but the top quickly came off. I was a little reluctant to pay the price of a genuine Karcher lance, but it has so far proved its worth. Coupled with my Karcher K5 jet wash, it hasn't yet missed a beat in helping get every last ounce of grime off my cars. The bottle design is particularly good as once the bottle is empty, you can fill it with your own snow foam mixture with ease. Highly recommended for anyones car detailing arsenal.

Worked well until the seal plug got stuck inside the gun and i couldn't get the lance fittings on had to retrieve it with long nose pliers now it happens every time I use it

It works but I have learnt the hard way to not to grip around the top when adjusting the spray, the bottle is too easily released, annoying when you’ve barely used any and you’ve spilt more than you’ve used.
