Question about Samsung Jet Bot AI+

The battery drains quickly, after 2 minutes it goes from 100% to 80%. Too high and can't go above the sofa. I had to return it for this reason. Otherwise, as for the vacuum function, it works well and cleans and picks up small dust particles. The access to the camera allowed me to visualise my home and I could manipulate it where I would like the hoover to go.
