KärcherFJ10 Foam Nozzle with Ultra Pressure Washer Detergent, Black, Yellow

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.

I've tried this product with all the best snow foam solutions. Unfortunately it just doesn't provide a thick enough foam, even on the thickest setting. I would avoid if you want the thickest foam

I have a K3.86 pressure washer and the bayonet fitting on this is too short to engage despite the description listing K3 models as compatible - it fits into the handle, but won't twist to lock. Ironically the Karcher extensions that came with the Karcher T5 patio cleaner I bought at the same time do allow me to attach it - albeit in a slightly clumsy way - so it would seem that the Karcher design team have failed to retain compatibility with their own products or want to troll all the existing owners with new design while retaining the old model names to cause maximum confusion.Incompatibility issues aside it seems to do a decent job if you can connect it.

Was a bit iffy at first thinking it would run down fast but I’ve covered my car 3 times now and it’s still more than half full. A little runny as it drips of the doors side fast. I try to leave it on for a few minutes then take the karcher brush over it. This is the lazy way and you’d get a better wash with a bucket of soapy water.

This is definitely a quality product for washing your car properly well worth buying for the serious motorist who loves a gleaming car

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.

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

The foam nozzle works well.The advertisement is slightly misleading; it gives the impression you’ll receive the nozzle, a container for foaming products, and a bottle of Karcher foam cleaner. There is no separate container, just the Karcher bottle.
