Roomba 694 Vs I3: Dissimilarities   


The Roomba i3 is more advanced than the Roomba 694, and the i3 comes with better suction power. The Roomba 694 has 550pa suction, which is significantly lower than the Roomba i3 (850-900pa). However, both vacuums can operate on bare floors and carpets and collect dust and grunge.  

Higher suction power provides better dust collection capacity to Roomba i3.  



To ask for convenience, none of these robot vacuums emit annoying louder noise that can distract your focus or horrify your pet. However, the Roomba 694 might seem slightly louder with its 70 dB noise level compared to the 64.9 dB sound of the Roomba i3.

Battery Life   

The Roomba 694 is ahead of the i3 in terms of battery life. Roomba 694 has a run time of up to 90 minutes which enables the machine to clean larger areas with a single charger.

Roomba 694 is the winner here!

Despite multiple surface cleaning capacities, the Roomba i3 also wins the navigation part with its mapping technology.
