This steam cleaner has certainly the best price / performance ratio which you can get. However, the cleaning effect is rather average. The water which comes out of the nozzle is no longer really hot due to the long hose. Limescale can thus hardly remove. But that's all the system and applies to other steam cleaners. The build quality is impeccable and you get a lot for your money here. The strengths of cleaner plays out at places where one normally does not come out right. For example, profiles of window frames, between the radiator etc. Very stuck dirt must first be softened / dissolved (lime). Despite a buy recommendation when a steam cleaner that is deliberately not high-pressure cleaners are. Therefore only 4 stars.
