Before recommending any product, I wish to mention that Robotic Vacuums although quite useful and trendy are expensive pieces of equipment in terms of its monetary price but on the other hand also quite economical for most people who are tied up with their busy schedule. These devices have built-in sensors for performing its tasks and most robotic vacuums can be operated remotely through a mobile app.
Now coming to the main point as to which Robotic vacuum cleaners in India to go for, I would like to mention that there are actually not many options available in this category in the Indian market but one such equipment that comes with the name of iRobot 900 Series Roomba 960 Vacuum Cleaning Robot is making rounds to be a promising product. There are a number of good verified user reviews for this robot vacuum that can be purchased from Amazon at around Rs.54,900.00 and it also works with home assistant like Alexa.
There are some minor downsides of the above iRobot 900 Series Roomba 960 Vacuum Cleaning Robot such as its runtime is a little on the lower side at 75 minutes only. Further, turbo mode is also not available while cleaning different surfaces like carpet etc. But overall, it does a perfect job of cleaning a 2BHK house in around an hour or so and makes your floor almost clean and dust free.
Alternatively, I would recommend considering the Mi Robot Vacuum that costs around 450 USD and can be imported from popular e-commerce sites like Gear Best etc. It has some really cool features and can smartly clean your home without having to attend it. Plus, it even charges itself on its own without any intervention from the owner's end.

So to conclude, if the price is not a concern, you may perhaps look for any of the vacuum robots as mentioned above. If you go for the imported one, be informed that apart from the listed price in the International e-commerce sites, it will also attract customs duty at applicable rates.
