Are robot vacuums useful for cleaning rentals?

[John Chapman]

Do you have any experience using robot vacuums for cleaning your rentals?   I’m considering using them this year and would be interested in your thoughts. Thanks

While occupied it isn't your job to vacuum for the tenants, while vacant it would probably be cheaper to use a regular vacuum because it should only need to be done once before it is rented again. Also you would have to be present to empty the small holding container on the robot vacuums.
