So what are these devices? Brand name?
Now that it is clear it is robotic vacuum cleaners. Yes they are vacuum cleaners. They suck up stuff. Just not all that well. No misrepresentation.
How do you know this?
Bought an iRobot vacuum cleaner on Choice"s recommendation. Absolute rubbish! Nowhere near as good as a Roborock that missed out on a recommendation.

The iRobot takes longer to clean and does a poorer job than out Xiaomi Roborock and does not have the function to return to the charger when low on power.
