Lately, iRobot has been put to task by its competition, especially Neato and now, Roborock. Just recently, they released a new robot vacuum cleaner called the S9 which replaces the older model, the i7.
From the prices, it is clear that the new model is the best choice, but is it the best bang for the buck?
We analyzed the similarities and differences between Roomba i7+ vs. S9+ so stick around to know if the extras are worth trading in your i7 for the new S9.
Before we go to the main business of the day, here is a short overview of the two vacuums.
The Roomba I series was released late last year and came with a revolutionary technology called iRobot CleanBase that empties the bin automatically.
This was a significant improvement, and at the time, it was the only self-emptying robot vacuum. Please note that the Roomba i7+ (7550) comes with the CleanBase unit while the Roomba i7 (7150) is a robot vacuum only but with similar features.
This time round, iRobot copied the D-Shape design from Neato and added a few more features to come up with the S series. The highlight of this model is the fact that it can work in tandem with the newly released iRobot M6 robot mop.
Now, let’s discuss the similarities and differences.
Roomba S9+ vs i7+ – Similarities
- CleanBase Technology – The S9+ and i7+ boast a self-emptying bin technology which automatically empties the small bin depositing the dirt into a larger bag. It can hold 30 days of dirt. Please note the base models don’t have the CleanBase unit but can work with it.
- 3-Stage Cleaning – The new S series employs the same 3-stage cleaning system – sweep, agitate, and vacuum. This is the same as the i7, but we expected the latest model to feature a mopping function, but this is not among iRobots plans as they released a separate robot which works with the S9.
- Filtration technology – The two Roombas have high-efficiency HEPA- style filters which capture 99% of dirt and filter down to 10 microns, unlike true-HEPA which filters down to 0.3 microns.
- Side sweeping brush – The S9 and i7 feature a single side sweeping brush that cleans the Roomba’s pathway, pushing dirt to the primary brushroll.
- VSLAM navigation – iRobot latest models feature a VSLAM (Visual Simultaneous Localization and Mapping) algorithm which uses sensors and a real-time camera to navigate around your house, and avoiding obstacles and falls.
- Recharge and resume – If you have large apartments, you can rely on these two vacuums as they will automatically recharge and resume cleaning autonomously.
- Imprint Smart Mapping – This is an addition in iAdapt 3.0, which allows homeowners to customize their cleaning efficiently. Decide which areas you want to vacuum, at what time. Both vacuums have the Imprint Smart Mapping Technology.
- Smart Connectivity – Both vacuums are compatible with 2.4GHz WiFI, allowing for Smartphone app operation and Alexa/Google Home control besides other integration.
- Virtual Walls – The new Roomba S9+ and i7+ use Virtual Walls to set up boundaries. They work well, but we expected them to feature digital boundaries which are easier to use.
Roomba i7+ vs S9+ – Differences
- Shape – While Roomba i7 is a round shaped Roomba, hut like all the other older models, we have a new shape in the S series dubbed PerfectEdge Technology. S9 and S9+ are D shaped like Neato, and this allows for better wall and edge vacuuming.
- Weight and dimensions – The new S9 is the thinnest Roomba at 3.5-inches high compared to the i7’s 3.7 inches. Regarding weight, the S9+ is a little bit heavier at 8.15lbs while the i7+ is just 7.45lbs.
- Suction power – The S9+ is more potent and delivers 40x more air power while the i7+ delivers 10x more air power. This is compared to the Roomba 600 series.
- Primary brushroll – The new S9+ has the same dual multisurface brushroll just like the i7, but then, this one is a little bit longer, and that is the difference.
- Bin capacity – Roomba i7 comes with a 16- ounce bin while the S9 comes with a smaller 13-ounce bin. Both have fill bin indicators.
- Imprint Link Technology – This is an exclusive feature in the new S9+ that connect it to its cleaning mate, iRobot M6. You can decide which rooms you want to be vacuumed only and which rooms are to be vacuumed and mopped.
- Runtime – Roomba i7+ disappointed with a short 75 minutes runtime. We are glad the new S9+ brings back the glory with a powerful battery that can last for 120 minutes.
- Anti-Allergen Seal – The new S9+ has been completely sealed to ensure captured allergens don’t escape. But this doesn’t make up for the lack of true-HEPA filters.
Who Should buy Roomba S9+?
The S9+ should be every homeowner’s dream. It is the latest model from the best robot vacuum brand and comes with a CleanBase, improved suction power, and syncs with the new iRobot M6 mop.
If you have a carpet, pets and a large apartment, this is the best choice. Notably, it boasts longer runtime than the i7, and will clean walls, corners and edges thoroughly courtesy of PerfectEdge technology that works in the same way as Neato’s CornerClever Technology.
Who Should buy Roomba i7+?
The new Roomba S9 is damn expensive, so if you want some pocket change, the i7 or i7+ is the real deal.
It cleans all bare floors and pet hair, but it’s not to be trusted for vacuuming high pile carpets and shag.
The i7 is also a great deal for homeowners with busy schedules as it comes with CleanBase Technology, meaning you can forget about floor vacuuming for a month.
