I was surprised to discover that if you run the robot vac once a day or even every second day it significantly reduces the amount of dust that ends up on other surfaces.

You just schedule it and forget it. As everyone says it doesn't do as good of a job as you do but the main benifit is it's consistent about doing that job more frequently.

If 20 minutes is all you need once a week, yeah it maybe doesnt make sense for you.

I have a dog and need to vacuum at least once a day, currently.

Without a robot vacuum, Id go crazy.

> I don't really see the point.

You save the 20 minutes once a week.

That's it. That is the whole point. A slight convenience. I use one in a 1 bedroom apartment.
