Introduced in fall 2018, Roomba i7+ is the first vacuum robot to automatically empty its own dustbin. In this post we present its specifications and discuss its differences with the very similar Roomba i7. Last, we summarize their pros and cons. The overall score allows to compare them to other high-end vacuum robots, including to older Roomba.


The table below lists the specifications of the Roomba i7 and i7+. We can see that the two vacuum robots are identical, except for one feature. While both vacuum robots support self cleaning, only the i7+ is shipped with a self cleaning base.

The base contains a vacuum pump that sucks out the dirt and transfers it to a disposable bag. It connects to the vacuum robot through an evacuation port, which is available on the Roomba i7. So, owners of the Roomba i7, can buy the base later, and it will work just fine.

Pros & Cons

Performance Analysis

The table below lists scores of Roomba i7+ and Roomba i7, regarding 3 different perspectives:

  • Pets & Allergy: If you have pets or some member of your family is allergic, you need a vacuum robot that picks as much hair and dust as possible. Cleaning should be efficient even with thick carpets. From this regard, both the i7 and the i7+ achieve a very  good score: 85%.
  • Large Homes: A good vacuum robot for a large home, should quickly clean a wide area. It should have refined scheduling, and should easily deal with multiple floors. Again, Roomba i7+ is very good with this regard. The i7 falls a bit behind. This is because only Roomba i7+ supports self cleaning. It compensate for the small dustbin, and reduces maintenance. The Roomba i7+ can perform several cleaning cycles in a row.
  • Affordability & User Satisfaction: Both vacuum robots are bad from this perspective. This is because of their price. Roomba are traditionally more expensive that other robotic vacuum brands. But, the Roomba i7+ comes with a cleaning base that is basically a second fixed vacuum. This unique feature makes the i7+ significantly more expensive than most high-end vacuum robots.
