Very good cleaner! Minus one star only because the packaging is small if you have to clean several carpets or upholstery and you have to fill the vacuum cleaner's tank with water many times.

It was used with the Karcher SE 4001 for cleaning carpets of various types (short pile, long pile, very long pile) and had good performance. There is a mild sense of freshness on the carpets after washing and drying, but nothing terribly intense.

It is enough to clean two cars with the vacuum or one large sofa. You don't need to use a large quantity. Very nice and pleasant clean scent

Very good, it's worth it especially if you find it at a good price!

With the RM 519 cleaning liquid from Karcher, I cleaned all my carpets, which are all wool and silk, and they look like new!!!! It's as if I had them professionally cleaned!!! So I know who I will trust once again in this area: Karcher!!!

The 1L was divided into zones of 100ml because I didn't have a measuring cup. The material is good but very expensive; is there any other tested, more affordable option?

It takes work for stains that have been there for a while. Small bucket when pulling water for carpet cleaning. Expensive product and large consumption I would say. It is great for cars. It needs work for home

I used it and it cleans perfectly fine. Follow the instructions exactly for better and accurate results.

It does the job. It cleans deeply without much foam. That's what you need for using a vacuum cleaner.

It was terrible and the couch looked brand new. It's as if I had a professional cleaning done. It really is worth its money

Very good product, compared to a no name, this one also has a nice scent but it removed a stain from the couch that the other one didn't clean. P.S. You need to pour the liquid with the vacuum cleaner, leave it for a few minutes and then suck it up, exactly as stated in the instructions.

Extremely effective cleaning results on carpets. The mixture was made with warm water at 45 degrees in the recommended proportions

Nice fragrance. It does the job. However, I will experiment with cheaper material. Nevertheless, it is decent. It cleaned car seats and some small carpets just fine.
