The quick answer

Both are great vacuums, but on most parameters, it is the s9+ that comes out on top. This is mainly due to the superior suction power and the smart mapping technology.

If you have pets and a lot of furniture, then the s-series is probably a better choice for you – although it comes with a correspondingly heftier price tag with bundles.

The j-series offers better value for money if you’re looking for something that’s easy to operate and doesn’t require too much babysitting. It’s perfect for busy people or those with allergies.

The bottom line is that if you’re looking for a powerful, reliable robot vacuum cleaner that can cope with even the messiest of pets, then the iRobot Roomba s-series is your best bet.

But if you’re after something a bit more budget-friendly and don’t have as many obstacles in your way, the j-series will do just fine.

And don’t worry about emptying it yourself – the Dust bin empties itself into the Clean Base Automatic Dirt Disposal so you never have to touch a dirty bag again! You’ll love how easy it is to keep your hardwood floors clean with this little guy!

Side by side comparison

Key features of the Roomba J7+ and S9+ that are shared:

Dual Multi-Surface Brushes

Both the J series and S series have two side brushes that help to clean edges and corners. It also helps to agitate and loosen dirt particles so they can be sucked up by the vacuum.

These brushes also adjust to different floor types which gives your floors a good clean.

Filtration

Both the J series and S series have pretty good filters. This means that 99% of particles as small as 0.7 microns are captured and removed from the air.

So, if you suffer from allergies or asthma, then these robot vacuums will be great for you as they will help to improve the air quality in your home.

Recharge and Resume

Both vacuums have the ability to recharge and resume cleaning. So, if it runs out of battery power while cleaning, it will automatically recharge and then continue where it left off. This is a really handy feature as you don’t have to keep restarting the vacuum every time it runs out of power.

Auto-Adjust Cleaning Head

The cleaning head on both vacuums auto-adjusts depending on the type of floor you are cleaning. This gives your floors a more consistently clean & helps to prevent any damage. This is a great feature as you don’t have to worry about adjusting the height of the vacuum yourself.

Spot Cleaning

Both the J series and S series have the ability to do spot cleaning. So, if there is a particularly dirty or dusty area that needs attention, you can simply press a button and the vacuum will focus its efforts on that specific area.

Compatible with voice assistants

Both the J series and S series are compatible with voice assistants. This means that you can control them using your voice. For example, you could say “Alexa, start cleaning” and the vacuum will start automatically.

Ability to create favorite routines

Both the J series and S series allow you to create your own cleaning routines. This means that you can choose which tasks the vacuum will carry out and when. For example, you could have it clean every day at lunchtime or only on weekends.

You can also set it to run automatically after a certain amount of time has passed since it was last used. This is a really handy feature as it means you don’t have to keep pressing buttons every time you want the vacuum to start cleaning.

Auto Dirt Disposal

The Roomba J series and S series have an auto dirt disposal system that whisks away dirt and debris as you clean. This leaves your floors virtually spotless.

Key Differences

The Roomba J series and S series are both great robotic vacuum cleaners. They both have a lot of features that make them stand out from the competition. However, there are a few key differences between the two vacuums that you should be aware of before making your decision.

Pet Waste detection

j7+ is able to dodge pet waste thanks to its PrecisionVision Navigation; S9+ on the other hand doesn’t have this feature. This makes the j7+ a better option for people with pets.

Suction Power

While the s9+ has a suction power of 40x, the j7+ has a power that is only 10x better than the previous model. This may not be a big deal for some people, but if you are looking for the most powerful vacuum possible, then the S series is definitely the way to go. Also having more suction power generally means that the vacuum can clean better and faster.

Cleaning Path

The cleaning path of the S series is wider than the J series. This means that it can cover a larger area in less time. So, if you are looking for a vacuum that can get the job done quickly, then the S series is definitely the one to choose.

Price

The Roomba J series is slightly cheaper than the S series. However, keep in mind that you may not get all of the features that are available with the more expensive S series. But the difference is only when you’re looking for a bundle. Without bundles, both models cost the same.

Mapping

The J series and S series both come with different navigations. But both do a relatively similar job in terms of efficient mapping.

This means that the vacuum cleaner will map out your home before it starts cleaning. This helps to ensure that every inch of your floor is cleaned properly.

Whichever model you choose, you can be sure that you’ll get high-end robot vacuums that will help to keep your floors clean and free of dirt and dust.
