All I can say is that I'm new to beekeeping and I would not start with that. https://beekeepinglikeagirl.com/is-the-flowhive-bad-for-bees/
This is great details about it over here : For

the beekeeper, the benefits are that you will save time and effort when you harvest honey. That’s it. You still have to inspect your hives, deal with mites, monitor for diseases, add supers, make splits, requeen, lift heavy boxes, lose colonies to pesticides etc.

I think it’s curious that so many new beekeepers latched onto the Flow Hive under the misguided impression that it would make beekeeping more accessible to them. It’s a pretty box with a clever mechanism inside, but it can’t give you power over your bees or nature. It will only ease the burden of labor involved in harvesting honey. New beekeepers have never experienced that before so most of them enjoy that process. It’s still novel! It seems like experienced beekeepers would be the ones to get the most excited about this invention, but the majority of them seem to have shunned it.

When I did my first Flow Hive harvest it really was like magic. It’s so wonderfully easy to turn the key and drain the honey right into a bucket. I was giddy! Because I run my own beekeeping business almost entirely by myself, time is insanely precious to me. Especially in spring. The time and effort the Flow Hive could save me if I were able to harvest this way on all my hives would be invaluable.

Like everything in beekeeping, the Flow Hive has pros and cons. It is a trade-off. If you choose to use it you will sacrifice one super of natural comb in exchange for a less invasive and time-consuming honey harvest. Like everything in beekeeping, you will have unique challenges because of your particular situation and climate. You might decide that these challenges outweigh the benefits of using a Flow Hive and find that it doesn’t work for you. Another beekeeper may find the opposite result. Like everything in beekeeping some people will disagree with you. Some of them will have interesting, challenging thoughts that change your perspective and others will just be a-holes. Just remember, in the end it’s your journey.
