- Best at Avoiding Obstacles: Roomba J7+
- Most Versatile: Roomba Combo J7+
- Best Overall: Roomba S9+
- Cheaper Than The S9+: Roomba I7+
All robots in this category don’t have smart navigation. It only pinballs around in a random direction. The options here are split into two groups – 600-series and E-series. 600-series Roombas are equipped with the rubber and bristle combo. In contrast, E-series robots have newer rubber extractors that require less maintenance.
Next in the hierarchy are the 900-series robots. There are three options: I3, 960, and 980. Currently, only the 960 is being sold on the iRobot website, while the 980 isn’t. All three robots traverse in straight lines, but only the 960 and 980 have the top-mounted camera, while the I3 relies on a floor tracking sensor. The I3 (“plus” variant) offer...
These are the top-spec Roomba options; three are available: I6, I7, and S9. These robots are the most expensive but have all the bells and whistles. Each has VSLAM and the “Smart Imprint” feature – it can save up to 10 map levels. The Roomba I6 and I7 products have the same motor, extractors, side brush, and navigation. Both products are the same r...
1. Counter-Rotating Brushes
All Roomba products come equipped with counter-rotating brushes. This feature has been a staple for all their products since the earlier generation 500-series robots. The difference is that newer Roomba options have bristle-less rubber extractors, whereas the older options (600 series) have a squeegee and bristle combo. This combination has been proven in tests to clean carpets well. The Roomba 690, even with its below-average airflow, was still able to pick up around a tidy 85.16% in deep cl...
2. Dirt Detect
Roomba products do well in cleaning tests because the dirt detection system instructs the robot to focus on dirtier areas. For instance, the 690 will go in a spiral motion around zones with more debris. Newer models like the I7 and S9 will do an extra back-and-forth pass.
3. Single Side Brush
Currently, all Roomba robots come with a single side brush. The design from the 614 to the I7 remains the same – three prongs with white bristled tips. However, iRobot changed the design with the S9 due to the change in shape, using a five-pronged brush with shorter bristles. You can see the difference in the photo above. The Roomba S9+ has a smaller diameter side brush versus the 980s longer pronged version. I like the Roomba S9+ side brush better since it’s at an optimal position for cleani...
1. Power/Airflow
Since iRobot doesn’t disclose suction figures (in PA), I used an anemometer to measure airflow directly at the nozzle. Here are the results: 1. Roomba 675:8.37 CFM 2. Roomba 690:8.2 CFM 3. Roomba E5:6.98 CFM 4. Roomba 960:9.33 CFM 5. Roomba 980:19.74 CFM (max setting) 6. Roomba I3+:7.27 CFM 7. Roomba I6+:8.2 CFM 8. Roomba S9+:25 CFM (max setting) You can see in the list above that only the Roomba 980 and S9+have high airflow (above 17 CFM), while the other variants fall in the sub-10 range. T...
2. Navigation
Earlier generation Roomba products like the 614, 675, 690, 860, 890, and E5 utilize a standard algorithm, which moves randomly. It pinballs around until the battery drops to 20% and then recharges. These models don’t have recharge and resume, so they won’t resume cleaning until you press the clean button. The 980 model, with its onboard camera and SLAM algorithm, is the first Roomba with intelligent navigation. Unlike the older Roomba options, it runs in neat back-and-forth rows and has recha...
Another difference between these robots is their cleaning performance. First, let’s look at the results. One issue with early-generation variants like the Roomba 675 or even the E5 is the rapid spinning side brush that scatters debris to a larger radius. Combine it with random navigation, and you’ll see why these robots don’t clean as well as later...
Pros
1. Avoids objects (including pet feces):The Roomba J7+ is the first with a front-facing camera, helping it avoid obstacles. 2. Self-emptying feature:The “plus” variant comes with a clean base station that empties the dustbin for you. 3. Holds up to 60 days of debris:iRobot says one bag can hold up to 60 days of trash.
Cons
1. Expensive:It’s only slightly cheaper than the S9+ despite not having the same cleaning performance. 2. Sub-par airflow:iRobot says that the J7+ has up to 10x more power than the 600-series robots, which is the same claim as the I-series robots. So, it still lags behind the S9+. The Roomba J7+is iRobot’s latest product and its first with obstacle avoidance technology. iRobot calls this “PrecisionVision.” It comes with a bold claim – it will avoid poop, or they’ll replace it for free. And af...
Bottom line
The Roomba J7+ will have the same performance as the I6 and I7 since it has the same specs. However the advanced obstacle avoidance system should avoid objects better than any other Roomba in this list. iRobot offers a POOP (Pet Owner Official Promise), but it’s only applicable to dry cat and dog feces. If obstacle avoidance is a high priority and you don’t mind paying the extra high cost, the J7+ can be an excellent option.
Pros
1. First Roomba with a mopping feature 2. A slight uptick in airflow means better vacuuming performance 3. Surprisingly efficient navigation 4. Industry-first retractable pad 5. Above-average deep cleaning
Cons
1. One of the more expensive options 2. Missed spots during the coverage test iRobot recently launched its latest product, the Combo J7+, its first robot vacuum/mop hybrid. Unlike other brands with a fixed pad location, Roomba utilized a retractable pad to avoid carpets during the hybrid run. However, it doesn’t have space to place a motor over the pad; thus, it doesn’t have an agitating element. While the Combo J7 can mop stains, its lack of agitation limits efficiency. I wouldn’t recommend...
Bottom Line
Despite the enhancements, I don’t recommend the Roomba Combo J7+ over the J7+ because of the price variance. Yes, it’s more versatile and cleans (slightly) better, but mopping limitations are a huge roadblock for me. If you need the added functionality, then go ahead and purchase the Combo J7+, but there are limitations to this product.
Pros
1. Outstanding at cleaning floors: The Roomba S9+ scored the highest averages in the cleaning tests. 2. Smart imprint navigation:This technology enables the S9+ to save up to 10 map levels and unlocks several features, such as selective room cleaning and keep-out zones. 3. Wide extractors:The square front of the S9+ increases its efficiency, especially cleaning edges where it picks up better than other Roomba options. 4. Auto-empty:This feature is available in the “plus” version and automatic...
Cons
1. Very expensive:The cost of an S9+ is equivalent to buying three or four high-end Dyson upright vacuums. 2. Short run time:It runs for only 75 minutes in the lowest setting. If you use the max, that number goes down to 45 mins. 3. No mopping: No Roomba products have a mopping option, like the Roborock S5 Max and S6 MaxV. You’ll need to buy an iRobot Braava, which is an added cost. The S9+ is the most expensive Roomba option, but it’s one of its best options when you factor in navigation, cl...
Bottom line
The Roomba S9+ is currently the best Roomba option for vacuuming debris. It offers superior performance over the other variants (except for the 980) at cleaning various surfaces. But the high-powered motor does come at a cost, and that’s the shorter run time (between 45 and 75 mins). So the question is, are you willing to spend on it?
Pros
1. Less expensive than the S9+:An excellent option for folks who want to enjoy the benefits of an S9+ without spending four figures on a robot. 2. Smart navigation:The I7+ retains the smart navigating features and map-saving capabilities of the S9+ 3. Empties the bin automatically:A second vacuum inside the charging base will clean the dust container’s contents. 4. Still excellent at cleaning carpet:The I7’s lower airflow makes it inferior with deep cleaning, but it’s still decent, picking up...
Cons
1. Still expensive:Even if it’s cheaper than the S9+, the I7+ is still more costly than most robot vacuums. 2. Not as good at cleaning the edges:The round shape of the I7 hampers its ability to clean edges versus the S9. It’s still decent but not as efficient in this area. 3. Fast-spinning side brush:One issue with round-shaped Roombas is the fast-spinning side brush that scatters debris. Another Roomba option with the “Clean Base” station is the Roomba I7+. Like the S9+, it empties the dustb...
What’s the difference between the Roomba I7 and I6?
You’ll notice I mentioned the I6 earlier, and I’ll expound on the difference between it and the I7. There isn’t much with product specifications as both use the same motor, battery, and extractors. But the I7 is costlier since it comes with more accessories, like the extra filter and side brush. Don’t expect much difference in performance because these are essentially the same robots, aside from some cosmetic variances.
