I Bought Hindware Nevio 90 1200 auto clean chimney last year. When I started to use products it works well. In starting suction is good no cooking aroma come to room. It has three suction modes available low, medium and High. Although LED light also available but it is useless.
Noise level is very less at starting, but the problem started in few month.
Suction level reduced and noise become louder. plates choked every week and auto clean not working properly. You have to clean suction plate every week if you cook oily food like non veg regularly.
Cleaning work of suction plate is a headache becuase dust and oil waste keep stuck inside it and you cannot dismantle it for cleaning. Although service center response is good in my case.
Also cleaning of whole chimney is difficult too.
I suggest to some other chimney who performed better.
