I "chose" this expensive version because it was the only one available to take away on the day. It did work, although I expected a bit more control of the mixture. I mostly used it near minimum but wanted to have the option for even less to be sure of my preference. The quick release bottle feature was a disaster as it is almost impossible to detach the gun without unintentionally releasing the container and having to grab it as it hits the deck and starts spilling its expensive contents. The answer is to release the bottle first, before twisting off the gun when swapping to a lance, but then you run the risk of knocking the open bottle over anyway with the unwieldy stiff hose. Such a faff and time waster, and you can't just set the assembled unit safely aside in one go. The best option is to buy the "simple" version in the first place. Having got that out of the way, the separate gun idea is so much better than having the pull-out feeder tube dipped in a vulnerable open bottle, as on my K5 Compact, and the switch to clean water doesn't have a couple of minutes of wasted soapy spray while the system clears through. Hooray! So buy a Kärcher spray gun by all means, but not this £40 version.

Very good product

I bought this product some time ago and have used it multiple times to great effect. It completely and fully serves its function and is very easy to use

Wouldn’t recommend this.

Works fine, although the clip for the bottle isn’t great as dropped off a couple of times losing some of the content in the process.

Not impressed

I bought this recently the dispenser bottle us fine but not impressed with the snow foam. I left it on fir 10-15 mins on a not very dirty car, after power washing it off with my Karcher the dirt was still there I had to wipe over the car with a sponge and then snow foam again dirt came off then. Would have been quicker with a bucket of water and some shampoo.

Not good value .

Very expensive and not very good. You can but much better quality at far cheaper price from alternative manufactures.

The yellow seal/connector got stuck in the lance on my K2 on first use. Broke the hose while battling to get the normal nozzle back in before I realised what the problem was. Looking at the reviews I’m not the only one, a disgrace that Karcher can’t make a product that works with their own equipment!

Great product

Tried this attachment for the first time today - I had it on the lowest setting and there was lots of foam - but was really disappointed after I rinsed the cars - so much so that I had to wash them both again ( the old fashion way this time ) to get them clean. Two cars at the lowest setting took about a third of the bottle of detergent - it’s quite expensive - about 6 car washes in total

Great foaming action, and turn it to the lowest mix setting for extended life of the shampoo. Still on my first bottle after at least 14 car washes.
