Pathetically. Don't buy. Either it is a fake or German company has severely disappointed me for the first time. Since the very first use it spits out all the water with a bit of steam. Hardly in a minute steam is over because so much water is spat out directly. Second time I tried again with 75% full water and waited upto tenminutes. Same useless effect. Spend the amount on CIF and scotch Brite .. highly effective and lasts for many months.
Comes Handy if your room is full of allergens due to high humidity. Very easy to use. Great technology from Germany.... just by holding in your hand you can tell how durable this product is. Unlike chinese products which are very delicate.
I bought a Karcher SC1 EU Steam Cleaner from Amazon on April 2nd 2017 vide invoice number HR-SDEC-138735191-1308 for a price of 3,999/-. I have since used this only a couple of times and with ONLY Distilled Water. It was also being used strictly as per the user manual provided. However, the A1 Safety Lock of the device is jammed and unable to open. Quite useless.
For a German brand that claims to be superior and for which we pay a premium price, this is highly disappointing. Considering the distress this has caused and the fact that the purchase was made just three months back, I would like to return the product and get a full refund.
For others considering purchasing a Karcher product, do not be misled by the fact that it is a superior engineered product. It is just so only to look at and hold. But nothing else. Functionally this product has been rather pedestrian with no real or tangible cleaning advantage. From a reliability perspective, the fact that it can get faulty even with full care and usage as per instructions in just three months and half a dozen uses at most, is practically zero.
