Did you ever own a any robot vacuum?

Robots without cameras have an extremely difficult time distinguishing obstacles like cables etc on the ground.

I have one, and specifically got one without a camera because I don't want that driving around my house. The first time it went through I made sure to stow cables and such, and I do a quick walk-through to make sure that none of the cats have barfed and that there's no obvious obstacles before I release the hypnodrone.

It still saves me time, which was the reason that I bought it in the first place.

Yes, I've had an early random pattern robovac and a newer LIDAR equipped one. Both worked well enough, the LIDAR device obviously much better though.

And yes, I keep the floors free of cables and clutter when it's vacuuming time. That isn't a hassle
