Overall, the 880 will be best for someone who appreciates gadgets and understands that a robot vacuum isn't designed to replace all other floor cleaning.
The display on the top of the vacuum includes the following buttons: Dock, Clock, Schedule, and Spot.
Hit the Dock button and your Roomba will return to Home Base to charge.
It has a height of 3.6 inches and a width of 13.9 inches.
It's finished in black (unlike the 790's blue finish), and has a carrying handle so you can easily transport it.
It includes two bristle-free extractors that rotate inward toward one another to speed airflow and increase suction.
There's also a high-efficiency vacuum, and a new XLife battery that claims to last much longer.
The company clearly wanted to maintain the Roomba's unassuming, minimalist design and sturdy construction.
It comes with a removable dust bin with an easy-access release button, left and right side wheels, a removable caster wheel in the front, debris extractors, and a spinning side brush.
And if you want to block off a particular room for cleaning, the Virtual Walls act like invisible fences; the 880 won't move past them.
You also have the option of turning your Virtual Walls into Lighthouses.
You can even sign up for a free account to test the site out for yourself before going all in.
