iRobot Roomba Combo J5 Plus two-minute review
The Roomba Combo J5+ is a combination robot vacuum and mop launched in summer/fall 2023. It is cheaper than many of the best robot vacuums, officially priced around $650 / £479 / AU$1,299, but often found on sale. The packaging is mostly cardboard, making components easy to identify. Setting it up involves unboxing, downloading the iRobot app, and mapping your home.
Its sleek design measures 13.8 by 3.6 inches and includes additional parts such as mopping cloths. The unit has bright green rubber brushes and a single-side sweeper, and the dustbin can be swapped for a mopping unit. It features an integrated light and camera for navigation. It is user-friendly but noisy, and you can control it via the iRobot app and integrate it into a smart home system if you use one.
Due to its single-brush design, it performs well on rugs but less so on hardwood floors. So, while it’ll keep things generally clean on a day-to-day basis, you’ll still need one of the best vacuum cleaners on hand to give your home a proper deep clean.
The mopping function requires swapping the vacuum bin for the mopping one and, unfortunately, doesn’t match traditional mopping in thoroughness. The vacuum also struggled with larger particles during our tests. While the vacuum navigates obstacles well, it may struggle with smaller objects and isn’t flawless at obstacle avoidance. One helpful feature is its ability to return to its charging dock when the battery is low and resume cleaning afterward.
iRobot Roomba Combo J5 Plus review: price & availability
- List price: US$649.99 / £479 / AU$1,299
- Launch date: September 2023
- Availability: UK / US / AU / worldwide
The Roomba Combo J5+ is available from most online stores, including Amazon, Best Buy, and iRobot’s site. It is also available in the United States, Australia, the UK, and other regions where iRobot products are available.
Because it’s no longer the most recent model in iRobot’s Roomba range, you can grab it slightly cheaper than the most up-to-date products that would set you back. In the US, the vacuum is just under $650, but you’ll find it on sale periodically and during large sales events like Black Friday.
The J5+’s relative age doesn’t diminish its features, as it still boasts all of the pros inherent in the Roomba range. It sits in TechRadar’s mid-range price bracket for the wider robot vacuum, and is decent value for a self-empty robot vacuum from a well-known and highly respected brand.

iRobot Roomba Combo J5 Plus review: design
- Not particularly lightweight
- Easy to set up
- Vacuum and mop bins need to be swapped for different functions
The Roomba Combo J5+’s packaging is mostly cardboard, with only the unit in a plastic bag. Smaller boxes neatly contain additional parts, including mopping cloths. This makes it easy to identify each component, which is particularly helpful for robot vacuum beginners.
Setting up the Roomba Combo J5+ is a straightforward process that involves unboxing the vacuum, downloading the iRobot app, creating an account to link the device, and mapping your home for future navigation. The iRobot app controls the vacuum, letting you start cleaning sessions, view and edit your home map, and set specific room-based cleaning tasks. It can also be integrated with any smart home system, allowing automated routines.
The Roomba Combo J5+ looks great, with a sleek, contemporary design that mirrors the signature shape and style of other vacuums from the brand. Measuring 13.8 inches across by 3.6 inches high, it’s the right height to navigate under sofas and cabinets. The top panel features a single clear button to avoid confusion. The black finish with a stocky dustbin adds to the premium appeal, even if the unit is quite large.
The underside features bright green rubber brushes and a single-side sweeper. Whenever you need to change modes, you can swap the bin for the mopping unit (included in the box).
There’s also an integrated light and camera that help the vacuum intelligently navigate and avoid obstacles. The overall setup is user-friendly and intuitive, though the relatively compact size of the vacuum unit does not automatically mean this is an ideal choice for small spaces. The dustbin accounts for much of the footprint, but the unit is also heavy. The weight contributes to noise levels as the vacuum moves across rooms, particularly in homes like mine. These homes have lots of furniture, corners, and raised wooden dividers between rooms.
If you plan to use the mop function, you must first swap out the vacuum bin for the mopping one. Fill the tank with your chosen solution and attach the mopping cloth. This is a key difference between the J5+ and Roomba Combo J7+, which can vacuum and mop simultaneously without swapping out any parts. If you don’t want the hassle of switching bins during your cleaning routine, you may want to opt for the newer model.
The Roomba was tested in the household of a black cat who sheds hair absolutely everywhere. The vacuum doesn’t disappoint in this regard, as it successfully picked up the abundance of pet hair from my floors. There was no issue with pet hair clogging the mechanisms, but I found that my longer human hair did wrap around the brushes, and they needed manual de-hairing after a while. I’d consider this one of the best robot vacuums for pet hair.

iRobot Roomba Combo J5 Plus review: performance
- Good at picking up larger particles but struggles with dust
- Obstacle avoidance feature only works for some items
- Mopping functionality has limitations
The Roomba Combo J5+ performed well during general use and specific tests, living up to the promise of its feature set. Dual multi-surface rubber brushes adjust to maintain constant contact with carpets and hard floors, and it promises to pick up everything from tiny dust particles to large debris, courtesy of a 3-stage cleaning system.
The device features a navigation system that maps your home, allowing it to transition smoothly between different floor types and navigate obstacles. The Roomba also boasts cliff-detection sensors that prevent falls down stairs or ledges, though I couldn’t test this in my ground-floor apartment. Notably, it can return to its charging dock automatically when its battery is low and resume cleaning afterward.
One useful feature of Roomba vacuums is the audio error messages. These messages suggest why your vacuum stopped operating in the middle of the hallway instead of leaving you to guess. So, if you find your vacuum stuck in a corner, you can hit the button and have it tell you what the problem is.
It’s worth mentioning that the Roomba Combo J5+ can be noisy during operation, especially when emptying the bin. It operates at an average noise level of 48dB, which is not overly loud but becomes significantly noisier during docking and emptying its tank.
Interestingly, the vacuum works more consistently on rugs than hardwood floors. This is mainly because robot vacuum brushes sometimes scatter loose dirt around the room, potentially missing some debris. However, rug cleaning performance remains stellar. Just note that the Combo J5+ might struggle with edges due to its single brush design, limiting its ability to reach corners and crevices.
Its obstacle avoidance feature is generally successful but not flawless. While it successfully avoids clothing, shoes, and pet droppings, it struggles with smaller objects like curtains and small toys. To be safe, you’ll still need to pick up various items before letting the Roomba loose.
The Roomba Combo J5+’s mopping functionality is adequate for surface-level dirt cleaning of hard floors. However, it doesn’t match traditional mopping thoroughness, especially for more stubborn or ingrained dirt.

In testing, the Roomba Combo J5+ struggled with fine dust while performing well with larger debris. For instance, it picked up biscuit particles easily but struggled with finer particles like flour. It also needed to empty itself multiple times when dealing with large amounts of debris, like rice spread across the floor.
After extended use, though, the Roomba Combo J5+ needs minimal maintenance. This included removing the main rubber brushes to clear them of hair and ensuring the side brush was obstructed. Occasionally, it should also be wiped down to keep its sensors clean.
- Performance score: 3.5 out of 5
iRobot Roomba Combo J5 Plus review: app
- Easy-to-use interface
- Accurate and customizable mapping feature
- Real-time updates on the vacuum’s progress
The iRobot app, available on iOS and Android, significantly enhances the Roomba Combo J5+ user experience with its various controls and features. Users can schedule cleaning sessions, view their cleaning history, and customize cleaning preferences in one place. It also offers access to Clean Map reports, where you can track the areas cleaned after each session.
The J5+ is compatible with Amazon Alexa and Google Assistant, offering voice-activated control for hands-free operation. The mapping feature accurately rendered the layout of my home. I regularly played with features like customizable room dividers and real-time updates on the vacuum’s progress. The app also allows for specific room cleaning and virtual barriers.
The app works remarkably well, providing an estimated time frame for task completion. Once everything is set up, you can select which rooms you want and don’t want to be cleaned. For example, if you command it to clean the kitchen, it will complete the task swiftly. It will send a push notification to your device and then return to its charging base.

How I tested the iRobot Roomba Combo J5 Plus
I sprinkled crushed digestive biscuits and flour on my kitchen floor to test the Roomba Combo J5+ on different surfaces in my one-bedroom apartment. The vacuum successfully picked up the biscuit particles but struggled with the flour, leaving some behind. I also spread rice on hard floors and carpets to simulate larger debris.
I observed how the vacuum and its accompanying app performed over several weeks, and thankfully, it only required occasional major cleaning interventions at this time.
