Roomba 694 vs i3: Powerful Battery vs Advanced Rubber Brushrolls

If you are searching for a smart and autonomous robotic cleaner to keep your house clean with minimal effort, this Roomba 694 vs i3 may come useful for you. Both of these round-shaped cleaners have Wi-Fi connectivity, a charge & resume feature, can work on most types of surfaces, and are compatible with voice assistants. However, since these models belong to different series, they naturally have some significant differences.

Suction and dustbin capacity

The iRobot Roomba 694 vs i3 comparison has shown that the Roomba 694 has a bigger dustbin than the i3 (600ml versus 500ml) which means it will have less need for frequent emptying. So, if you have a lot of hairballs and pet hair to clean up after your pets, you might want to go with the Roomba 694.

Comparing iRobot 694 vs i3 suction level, it should be said that both vacs have a mere suction power. However, since the Roomba 694 has 1670 Pa, and the i3 has 1800 Pa, it’s clear that the last one is a more powerful option.

Using area

The i3 appeared to be a winner in the iRobot i3 vs 694 using area comparison since it can cover an area of 1800 square feet while its competitor can cover 1200 square feet. Nevertheless, the battery life of the Roomba 694 is truly impressive as it can run for more than two hours (around 130 minutes) on one charge. This means it will automate its cleaning cycle over a longer period than the i3 which has a maximum battery life of around 90 minutes.

Noise level

When it comes to Roomba i3 EVO vs 694 noise level comparison, the Roomba 694 appears to be quieter than the i3. The i3 has a significantly higher decibel rating than its competitor — 63 dB vs 55 dB. If you don’t stay close to the Roomba 694 while it cleans, it seems nearly silent. The i3 also can’t be called a noisy vac but still, loses to its opponent in this section.

Carpet cleaning

The i3 has a higher suction power which makes it a better variant for cleaning thicker and deeper-pile carpets. The i3 is also slightly better at picking up pet hair from rugs thanks to advanced dual multi-surface rubber brushes than the Roomba 694 which has a lower suction level and is equipped with a standard bristle brush. So, if you compare the Roomba i3 vs Roomba 694 carpet performance on high-traffic areas where pet hair accumulates quickly, you will notice that the i3 helps get rid of it better.

Roomba 694 pros & cons


  • The Roomba 694 has an affordable price; it’s among the cheapest robotic vacuum cleaners on the market.
  • The cleaner doesn’t get stuck on uneven surfaces.
  • It announces errors by voice, so you don’t have to periodically check if everything is okay with the vac while it cleans.


  • It takes a lot of time for the cleaner to identify cords and toys on its way.
  • The bristle brush needs to be cleaned and untangled from the hair on a regular basis.

Roomba i3 pros & cons


  • This vacuum cleaner cleans in neat rows instead of wandering the surface in a random manner as many other robotic cleaners do.
  • It slows down when it spots any objects or walls and never bumps into them.
  • The i3 navigates very well even in low-light conditions.


  • The side brushes move way too fast and just scatter some debris around.
  • The filter will clog up pretty fast if you have fluffy pets.
