I have a Roborock robot vacuum, a portable Xioami one. If you're going for a plug in one. I would recommend a "shop" vacuum. They will outclass the consumer ones, will have better suction, bigger bin and be able to take more battering. Most also come is a wet dry vac too, so if you have any big spills you can use the vacuum.
The only downside is they don't look that fancy
