I bought the JetBot+ Robot vaccum about a month ago and so far it has been overall a good experience. 

Pros:
1. Does its job of cleaning floor especially hard wood flooring. 
2. Has a decent trash bag.
3. Fully automatic as it should be.*

Could do better at:
1. Identifying obstacles. It fails to pick up wires and ends up in a tangle needing manual intervention.
2. Lifting the robot manually leaks dust onto the floor. Could do better at locking the dust.
3. Occasionally gets stuck around obstacles, especially if something has been moved.
