Kyvol Cybovac S31 Video Review

Hello! There are a few features on this table listed as "No" that are actually available on the device. The following are included as features:

Full Bin Detection: You'll receive a notification when either the bin on the robot, or the auto emptying vacuum bin is full.

Multi-Map Support: You can have up to five stored maps.

No-Mop Zones/Virtual Walls: This device includes the ability to set both No-Mop Zones and No-Vacuum Zones, as well as setting up virtual walls, all within the app.

IR Remote: This device comes with a remote and two batteries.

----
Aside from the IR Remote (which I thought came with all these devices, so I'm not sure why it's listed as a no), I believe at the time of writing this review, these features did not come with the device, and were most likely added as feature updates later in life.

Note: I have only owned my device for a day, but that's been long enough for me to learn the features and use them. The app has improved greatly from its beginning days I hear.

Hello,
Thank you so much for noticing and reaching out, I've fixed the table. Multi-mapping and no-mop zones are not mentioned on the product page on Amazon, perhaps Kyvol added these features recently. Could you please tell me if there is an ability to adjust water flow in the app? Not sure if the water tank is electronically or gravity controlled. Thanks!

It says on amazon that this robot vacuum has auto carpet boost. This website said it does not. Is amazons info incorrect? Or is this site? Thanks

You are right, it has the carpet boost feature. We didn't notice that when collecting the information. I've updated the table, thank you!

Why are there so many n/a fields? Charge time, Mop container size, etc

When the robot was released there was not much info about it. Fixed what is now known
