Roomba j7/j7+ vs. Roborock q5/q5+ Comparison

Let’s discuss the points covered in this table in more depth.

Differences between Roomba j8+ and j7+

Following are the differences between the Roomba j8+ and the Roomba j7+.


The Lithium Ion battery in both models is of high quality. The Roomba j8+ has literally twice the battery as the Roomba j7+. Its 4420 mAh battery capacity gives a runtime of 120 minutes. But the j7+ can only run for up to 100 minutes with its 2210 mAh battery. Both Roombas take 2 to 3 hours for a complete charge.

Since the Roomba j8+ has twice the battery capacity of the Roomba j7+, it is the better choice.

Accessories: Roomba j8+ vs. j7+

Both Roombas come with an extra side-sweeping brush. The major difference in this section is between the number of dirt disposal bags and the filters available with each model.

  • The j7+ has only two dirt disposal bags, but the j8+ has 4.
  • The j7+ comes with an extra HEPA filter, but the j8+ has 2 extra HEPA filters.

As the Roomba j8+ has more accessories, it should be your ideal option, considering the same price range.

Availability: Roomba j8+ vs. j7+

The Roomba j7+ is available online on pretty much any e-commerce website. But that’s not the case with the j8+. You can buy it only from Costo’s website, making it a Costo-exclusive model.

Please note that you need a Costco membership to be eligible to purchase the j8+. Costco membership is available for purchase at $120.

So, if you are a Costco member, get the Roomba j8+. Otherwise, go for the Roomba j7+.

Similarities between Roomba j8+ and j7+

Both these Roombas are available at almost the same price. They have the exact same design. With similar dustbin capacities and automatic dirt disposal systems, they don’t bother you to empty their bins manually.

They give almost the same cleaning performance with the same suction power and airflow. They even use the same 3-stage Cleaning System. Even the vSLAM and iAdapt 3.0 Technology are the same for both vacuums.


When comparing the Roomba j8+ and j7+ models, the decision largely depends on whether you are a Costco member or not. If you have a Costco membership, the Roomba j8+ is the better choice due to its longer battery life, additional dustbin bags, and extra HEPA filters.

However, if you are not a Costco member, the Roomba j7+ is a suitable option, as you will have to get the Costco membership separately for $120.
