The iRobot Roomba Combo J5+ is a budget-friendly 2-in-1 robot vacuum and mop that combines dependable cleaning with several useful convenience features. Its Clean Base automatically empties the robot’s 460ml dustbin into a 2.5L disposable bag and can hold up to 60 days of debris. A single camera and LED support obstacle avoidance, while Dirt Detect helps the robot spend additional time cleaning dirtier areas. The app provides multilevel maps, virtual barriers, and no-go zones, along with compatible virtual-assistant controls. Official specifications include up to 180 minutes of battery life and support for crossing thresholds up to 16mm. See additional info
Let’s explore what this robot vacuum can do for your home cleaning.
iRobot Roomba Combo j5+
You can get the iRobot Roomba Combo j5+ with or without the auto-empty bin. And the version without it is simply called the Roomba Combo J5.
Also, it’s important to distinguish these models from the i5 and i5+, which, while more affordable, lack the J5’s advanced navigation features like camera and obstacle avoidance. Those models offer basic floor-tracking, which limits what you can do in the app compared to the j5 and j5+.
Roomba Combo j5+ Evaluation and performance
For our Roomba Combo j5+ review, we put the robot vacuum through a series of tests, and the Combo j5+ did really well. It was on par with other high-end Roomba products.
Vacuuming carpets and hard floors
The Combo j5+ didn’t disappoint in our vacuuming tests, and among all the Roombas we’ve tested (all performed well, by the way), the j5+ did better than average in our deep clean test. This test checks how well it picks up deeply embedded sand in carpets, and the j5+ scored 82, above the average score of 77.
It could handle surface debris and pick up fine to extra-large debris with no issues on both hard floors and carpets.
Grabbing hair was also a breeze. The pick-up was efficient, with minimal tangles on its dual brush rolls, which is great, especially if you have pets.
Mopping
The Roomba Combo j5+ mopping feature was designed to offer a more budget-friendly alternative to the premium j7 and j9 combos. Both have mop plates that lift automatically and recognize carpets and hard floors, adjusting for each floor type on autopilot.
However, the Combo j5+ mopping system works a bit differently. You’ll need to first add your no-mop zones using the app. Then replace the regular dust bin with the dust bin and mop combo, which you fill with water. Once that’s done, it will simultaneously vacuum and mop your hard floors.
But, unlike its higher-end counterparts, the Combo j5+ robot vacuum doesn’t apply downward pressure, making it best suited for light-duty mopping. Its performance on tough stains also varies, excelling with some and less effective on others.
For example, in our dried-on coffee stain test, the j5+ did fantastic but performed averagely with the dried-on grape juice torture test.

iRobot Roomba Combo j5+ features
Auto empty bin system
The Clean Base auto-empty bin system of the Roomba Combo j5+ is a significant convenience factor, as it simplifies maintenance and promotes a cleaner home environment with minimal effort.
When the j5+ returns to its Clean Base, it automatically transfers debris into a disposable bag.
Each bag can hold up to 60 days’ worth of debris, according to iRobot, which is ideal for busy households.
Further, the overall design of the Clean Base is better than many others we’ve seen. Certainly one of the better-looking auto-disposable bins available.
Obstacle Avoidance System
Another great thing about this robot vacuum is its impressive obstacle avoidance system — a rare feature for products in this price range.
The front-mounted camera automatically identifies and steers clear of common household obstacles, Including toys, cords, and pet waste. iRobot even has a sort of one-year guarantee called P.O.O.P. (or Pet Owner Official Promise), which replaces your unit if a ‘pooptastrophy’ occurs.
In our obstacle avoidance tests, the Combo J5+ scored above average, scoring a 9 out of 12, which matches the Combo j7 and top-of-the-line Roomba Combo j9+ scores.

App
The app for the Roomba j5+ aligns with the advanced features of the high-end J series. It offers enhanced maps, customizable keep-out and no-mop zones, various routine options, and smart home integration, among other features.
These intelligent app features of the robot vacuum add significant value, allowing you to personalize your vacuuming experience to fit unique household needs.
Roomba Combo j5+ navigation
To navigate, the j5+ uses a blend of sensors, cameras, floor tracking, and advanced algorithms for precise mapping and efficient cleaning paths. So, it should navigate your house without problems and handle complex layouts and various floor types. Its obstacle avoidance feature, which was covered earlier, illustrates this.
Cons of the iRobot Roomba Combo j5+
While the Roomba J5+ boasts many strengths, it’s important to consider the potential limitations. Here are the things we found.
Mop pad bin
On the one hand, the mop pad bin feels like an afterthought, which is a good thing, especially since there’s potential for backward compatibility with older models… That is if iRobot decides to make such versions. On the other hand, the lack of a drip tray is noticeable. You’ll need to keep an eye on it to remove the mop pad bin when it finishes its run.
Carpet recognition when the mop pad is attached
With the Roomba Combo j5+, we had to set up no-mop zones through the app to keep it off carpets when in mopping mode. Auto carpet detection doesn’t work in this mode, which leads to a slight loss in accuracy. However, it still surpasses many cheaper mopping robots that don’t have app-based zone management.
Price
We noticed the price of this vacuum and mopping robot fluctuates weekly, which made the decision to buy more challenging.
When offered at a substantial discount off its list price, it’s a no-brainer deal because the product is way better than 99% of the low to midrange robot vacuum combos on the market — especially since it has obstacle avoidance. However, with smaller discounts, such as 10% off, it may be worth investing slightly more for a higher-end model like the Roomba Combo j7+.
Roomba Combo j5+ review: value and final thoughts
The iRobot Roomba Combo j5+ is very versatile, providing high-end features like smart navigation, obstacle avoidance, and mopping capability in a more accessible price range. If you want something that’s budget-friendly yet has advanced features, then the Combo J5+ might be for you.
