Roomba j7+ vs Roomba s9+

Robot vacuum cleaners are autonomous and can work on many types of flooring, including tiles, carpets, and hardwood. These devices are fully automatic and can work based on user-defined schedules. With 360-degree sensor coverage, they can crawl easily under beds and tables.

Unlike using standard vacuum cleaners, you don’t need to set aside time to clean up your home. Unlike your vacuum cleaner, these robotic cleaners are compact and can park themselves at an assigned spot after completing their tasks. Because they can easily fit in under your couch or bed, you don’t need to worry about allocating special storage space for them.

Robotic cleaners are so convenient because they have a self-charging feature and a docking system. When your robot runs low on battery, it will automatically dock and charge itself. After fully recharging its battery, the robot vacuum cleaner will resume its task based on schedules.

You may operate the robot cleaner with remote control if your home is unusually messy due to social or cooking activities. You can ensure a healthier living environment because pollen, debris, dust mites and dirt can be removed effectively from carpets. Health issues like allergic reactions or breathing problems can be minimized if you keep your home clean.

Differences of Roomba j7+ vs Roomba s9+

In terms of capabilities, Roomba j7+ and s9+ are quite similar with their excellent cleaning performance and advanced navigation features. Compared to the regular j7 and s9, these plus versions are equipped with a self-emptying clean base. Design, hardware, suction performance, accessories, and other features are identical, between the regular and plus version. But, there are other differences of Roomba j7+ and s9+ to be aware of:


Roomba j7+ has a round design, making it easier for the device to make turns slightly tighter. With its D-shaped design, Roomba s9+ works better at cleaning along edges and into corners. Roomba j7+ is bigger with 13.34-inch in diameter and lighter at 7.49lbs. Roomba s9+ is smaller at 12.25-inch in diameter, but heavier at 8.15lbs.


Both models have four major underside components. Spinning brush collects debris in corners and along edges. Edge sensors prevent both models to fall off or navigate off of edges. A brush roll removes dust, debris, and dirt from carpets or mats. A suction port sucks out any debris, which will be deposited to the dust bin. Due to its D-shaped design, Roomba s9+ has shorter bristles on its spinning brush. On Roomba s7+, the brush roll is shorter and located between the wheels and on Roomba s9+, its brush roll is located at the front. The Roomba j7+ has a front wheel, which allows better maneuverability, compared to the Roomba s9+ with its rear wheel.

Mapping and navigation

Both models are equipped with Imprint Smart Mapping (ISM), digital mapping, an onboard camera and straighter line navigation. With your iRobot app, you can assign names to each room in your house. However, Roomba j7+ has a couple of extra bells and whistles. The obstacle avoidance feature of Roomba j7+ is a combination of onboard camera and sensors, which can detect and avoid smaller objects, such as toys or Lego pieces. It also has the Clean While Away feature, so you can set Roomba j7+ to clean up the house only when you are away. Roomba j7+ and s9+ have comparable clean-up performance, but with its extra features, the former works better in some situations.


Roomba s7+ has a larger bag that can hold up the 60-day worth of debris, while the Roomba s9+ can accommodate only 30-day worth of debris, so you need to empty it more often. It is important to note that both models have different types of HEPA filters.
