Symphony sumo junior room cooler I had been used it for near about 8 to 10 years and till now not found any maintenance issue.
Firstly I used it in the room and found it is not able to cool the room despite of cooling it starts giving hot air and made room hot so it is my humble request to use it outside the room in window basically it is a window cooler.
Capacity of tank water tank is also found very less when the peak summer days you have to fill 3 to 4 times for full day running .
So keep size in mind while purchasing .
Due to small size ease of handling . overall average performance in a reasonable price range .
