I got this Karcher SC1122 steam cleaner a year ago. Used it less than 3 times since bought. The kit is just as good as new.
The streamer is very good in cleaning the air-con cooling coil and Drainage Pipe as what I used that for. But after the second clean, I got lazy to use it, since that we are not heavy air-con users. And I just left the set inside our storeroom. Until yesterday, when doing the clearing inside the store. Then I decide to clear out this cleaner.
This piece of Germany made steam cleaner cost me S$428 when I bought it. Now I am willing to let go at $350 (price can be neg with serious buyer).
