Review: Neato BotVac 80 Robot Vacuum 

 Methodical and planned cleaning.  The Patented Neato Technology provides the Laser-guided navigation system that scans and maps the room, plans and methodically cleans, instead of just bumping around.

Square Shape
With its squared edges, it reaches corners easily using its suction-backed brushroll resulting in better cleaning of corners than you get from the  Roomba

There is a large dustbin.
You can program the Neato with its cleaning schedule.

If the battery runs low, your Neato knows it and then goes and puts itself on the charging base.  You don't need to worry about forgetting to charge it.

There isn’t any Smartphone connectivity.
