Each one of these robot vacuums comes with a clean base. Right after the robot vacuum is full of dirt, dust, and debris, it will go to the base and empty itself out.
To use this base, though, you will need dirt disposal bags. Each robot vacuum comes with bags, but the i6+ comes with just one, and the Roomba i3+ and i7+ come with two. For the most bags, though, you can purchase the i8+, which comes with four bags.
The dirt, dust, and debris this robot vacuum can clean up will, more likely than not, be filled with allergens. All of these allergens can be removed using a high-efficiency filter. If you purchase the i6+, however, you will not receive access to such a filter.
For a cleaning experience that is precise, yet hands-off, you can use a virtual wall barrier. Using one of these devices allows you to block off entire areas and spaces, ensuring that the robot vacuum doesn’t cross. You will need to purchase the i8+ to receive a virtual wall barrier.

For the most part, each one of these robot vacuums offers the same cleaning specifications. But, the amount of space these robot vacuums can clean does differ a little bit.
The i3+ is capable of cleaning a space that is no more than 1,830 square-feet. Both the iRobot Roomba i6+ and Roomba i7+ can clean spaces that are 1,991 square-feet. For especially large spaces, the i8+ can clean 2,153 square-feet.
None of those measurements differ very much, so each robot vacuum provides a similar vacuuming experience.
Roomba i3+ vs i6+ vs i7+ vs i8+ Battery
| Roomba | i3+ | i6+ | i7+ | i8+ |
| Battery Capacity | 1800 mAh | 3300 mAh | 3300 mAh | 2210 mAh |
| Running time | 75 | 75 min | 75 min | 90 min |
| Charging Time | 150 | 120 min | 120 min | 120 min |
| Sensors | ||||
| Carpet Boost | no | yes | yes | yes |
| Cliff Sensor | yes | yes | yes | yes |
| Dirt Detect | yes | yes | yes | yes |
| Full Bin Indicator | yes | yes | yes | yes |
The i3+ takes 150-minutes to charge. But, the other three robot vacuums take just 2-hours to charge.
As for the runtime, the i8+ can last for 90-minutes on a single-charge. The other three robot vacuums, however, can only last for 75-minutes on a single-charge.
Every single one of these robot vacuums possesses the exact same sensors. That is, except for the i3+, which does not possess a carpet boost sensor. Because of this, the robot vacuum won’t adjust the amount of suction it’s using when it goes onto a carpeted surface.

Just as with the sensors, the only robot vacuum that differs from the baseline specifications these vacuums offer is the i3+. With a weight of 10.36-pounds, the i3+ is heavier than the others. But, for the most part, this weight won’t make much of a difference, since the robot vacuum will be on your floor more often than not.

Conclusion
Each one of these robot vacuums is fantastic. For the best vacuuming experience possible, you cannot go wrong with the i8+. But, the i8+ is expensive, and if you want something that’s almost just as good, but cheaper and only a little less convenient, you can’t go wrong with the i3+, i6+, or i7+!
