Please DO NOT BUY this. It just worked for 1 month for us, we are crying with customer service, in fact they also admit they get the same issues from a lot of customers. In short it just worked for 1 month and stopped working. Cleaning is complex, service is too poor...PLEASE STAY AWAY.... they spent money in ads in various sources instead the company can spend money to give a quality product so it works at least for 2 years. I have checked with few of my friends and all of them have to say the same story.
People should share their experience and save other people from these type of third rated products.
