The iRobot Roomba i7 is a robot vacuum with a unique automatic dirt disposal built into its charging dock. Thanks to this design, you don't have to empty the dirt compartment as frequently. Its companion app gives you access to different features like setting up virtual boundaries and scheduling clean up times. It also automatically adjusts its head to suit your floor type and can focus on cleaning particularly dirty areas more thoroughly. Unfortunately, it struggles to clean large debris on bare floors and it has trouble with smaller debris on carpet. There are several parts that need regular maintenance and replacement, which makes its recurring costs quite high.
Our Verdict
While the iRobot i7 delivers good pet hair pick-up performance, it lacks some features that come in handy for pet care, like mopping. As a robot vacuum, it can map out your house and take the most efficient path to ensure your room gets cleaned. However, hair can get caught in the brushroll, and you may need to intervene and detangle it. Unfortunately, although it's well-built, it has several parts that need frequent maintenance, and its recurring costs are quite high.

Differences Between Sizes And Variants
There are two variants of the iRobot Roomba i7: the basic variant, referred to as the i7, and the i7+, which comes bundled with a a self-emptying base station. We tested the i7+ variant, and you can see its label here. That said, both vacuums are mechanically identical with the sole exception of the i7+ having a slightly different internal dustbin, which features a debris disposal port covered by a rubber flap. You can buy a basic i7 and purchase the self-emptying base station later down the line, which also includes the redesigned internal dustbin. Regardless, both models should deliver similar overall cleaning performance, though the inclusion of the auto-empty dock does reduce hands-on maintenance requirements.
Compared To Other Robot vacuums
The iRobot Roomba i7 is a high-end robot vacuum. It has a unique automatic dirt disposal built into its charging dock, so when the robot returns to the dock to charge, it empties its bin. While this means it has a larger dirt compartment than most other robot vacuums, the external dirtbag is another recurring cost that adds up over time. Other than this feature, its performance is somewhat similar to the Neato Botvac D7 on carpet but it struggles a bit more on bare floors.

The iRobot Roomba i7 and the iRobot Roomba j7 each have advantages, meaning one may suit you better than the other, depending on your needs. The i7 performs significantly better on low-pile carpets and charges faster but has a shorter battery life than the j7. The j7 also clears more debris on high-pile carpets and has a unique hazard identification capability to avoid obstructions like pet waste.
While both vacuums are almost identical, the iRobot Roomba i8+ ultimately represents a better deal than the iRobot Roomba i7. The i8+ comes with an additional dirtbag for its self-emptying station, an extra high-efficiency filter, and a virtual barrier device that you can use to set up no-go zones without opening the vacuum's companion app. The i8+ also uses a higher-capacity battery that yields a longer runtime; however, it does take a little longer to recharge.
The iRobot Roomba i7 and the eufy RoboVac X8 each have advantages, meaning one might be a better fit for you than the other, depending on your exact requirements. The iRobot is better built, charges substantially faster, maneuvers itself more effectively, and clears more debris on low-pile carpets. It also has a HEPA filter and a more advanced suite of automation features, most notably its self-emptying function. However, the eufy incurs lower recurring costs, lasts much longer on a single charge, and clears more debris on bare floors and high-pile carpets.
The iRobot Roomba S9 is better overall than the iRobot Roomba i7. The S9 performs better on all surface types, feels better built, has lower recurring costs, and has a maximum battery life that's more than twice as long as the i7. The i7 does come with an automatic dirt disposal feature. This effectively gives it a much larger dirt compartment via an external dirt bin that it can return to when full. However, the same option is available for the S9 at an added cost.
Test Results
The iRobot Roomba i7 7550 model has great build quality. Its body is made from hard plastic, while its wheels are rubber, which makes the vacuum feel durable overall. While the dirt compartment is also plastic, it feels like it could break if dropped. That said, this vacuum has a carrying handle to make it easier to bring it from one space to another.
The iRobot i7 is difficult to maintain as there are several parts that need regular cleaning. Luckily, they're all easy to access.
- Dirtbag: The dirtbag is located in the charging dock. It can be removed by opening the lid and pulling out the bag. There's an indicator light that changes from white to red to let you know when to replace the bag or if there's a blockage.
- Dirt compartment: The dirt compartment is found directly on the vacuum. It can be pulled out by pressing the button on its back side. You can wash this part with water and wipe it with a dry cloth or tap it against your garbage bin to dislodge dirt. You should clean this part after every use.
- Brushrolls: The brushrolls are easily accessed by removing the brush guard under the vacuum. You can clean this part whenever there are hairwraps by using your hands or scissors. It can be a bit difficult to get the brushroll to fit back into place once removed, though. You should clean this part once a month or twice a month if you have pets.
- Side brush: You need a screwdriver to remove the side brush. You should clean it by removing tangled hairs once a month or twice a month if you have pets.
- Filter: The filter is located inside the vacuum's dirt compartment. You can tap it against your garbage bin to remove any debris stuck to it once a week, or twice a week if you have pets. Note that this part can't be washed.
- Wheel: You can pull the wheel out of its cavity and push it out of the socket to dislodge any hair or debris stuck to it. You should clean this part every two weeks.
- Sensors: The vacuum's sensors should be cleaned once a month with a dry cloth.
Any part that's washed in water should dry for 24 hours before use again.
Unfortunately, there are a lot of recurring costs with this vacuum, depending on your usage.
- Dirtbag: The disposable dirtbag needs to be replaced when full.
- Side brush: The side brush can be removed and replaced every 12 months.
- HEPA filter: The HEPA filter needs to be replaced every two months.
- Front caster wheel: The wheel should be removed and replaced every twelve months. You can purchase this part from iRobot.
Luckily, iRobot sells a 'Replenishment Kit' that contains three side brushes, multi-floor rubber brushrolls, and three HEPA filters. Still, you may want to take a look at the yeedi vac station if you're looking for a robot vacuum that incurs lower recurring cost, though be aware that it lacks a HEPA filter.
The i7+ variant of this vacuum has a reasonably compact footprint. It's a fairly small robot vacuum that can mount itself on its docking station and automatically empty its dustbin. The self-empty station is of the same design bundled with other iRobot '+' models. This docking station is taller than most robot vacuum self-empty docks but also noticeably narrower, making it easier to fit in tight spots.
The iRobot i7's internal dustbin is pretty small. This isn't a major issue if you purchase the i7+ variant, which comes with a self-empty base station, but you'll be dumping out debris manually if you don't go for the model bundled without the base station. Like many other iRobot models, this vacuum has a fill sensor and will alert you when the dustbin or dock station dirtbag is filled.
This variant of the iRobot i7 comes with a self-empty base station. It uses 2.4L dirtbags, which are similar in size to most other self-empty stations. The station is advertised as having sufficient capacity for 60 days' worth of cleaning sessions, though this can vary depending on how often you use it. You can wrap up any excess length of power cord behind the base station.

The iRobot Roomba i7 has excellent battery performance. Since it auto-adjusts to the floor type it's cleaning as well as to the amount of dirt it detects, your total battery life may vary, though it uses a smaller-capacity battery than the otherwise very similarly-designed iRobot Roomba i8+, resulting in a shorter overall runtime. However, the battery recharges in about an hour and a half, which is excellent. There's also a 'Clean' touch button that turns from white to red when the battery is low. The companion app also displays its battery level. If you want a robot vacuum with a much longer maximum battery life, consider the iRobot Roomba S9, which can supply over two and a half hours of continuous runtime on its least powerful setting.
The iRobot i7 has a few extra features. The robot can detect the surface it's cleaning and sense how much dirt is on the floor to better concentrate its power. It also goes back and forth over certain areas that require more cleaning, and the head height automatically adjusts to suit the floor type better. However, you won't be able to manually adjust this setting. Unlike newer iRobot models, such as the iRobot Roomba j9+, it lacks a real-time hazard avoidance system, so make sure its cleaning area is free of obstacles like socks or shoes before letting it run.
This vacuum is adequate for clearing hard surfaces. Large debris like cereal is no issue, though the side brushes tend to toss around medium debris like rice and push fine debris like sand around the floor. If your floors are particularly dirty, you'll need to have the vacuum clear the same area multiple times.
This model performs decently on high-pile carpet. It can clear most medium and large debris, like rice or cereal, but fine debris, like sand, is more challenging, particularly when deep in the carpet fibers. Walls and corners also prove difficult, like on many other robot vacuums with a circular design.
This robot vacuum delivers decent performance on low-pile carpet. It clears most debris easily in a single cleaning session, although fine debris like sand may be more challenging and require another pass. Walls and corners are a pain point; fine debris tends to get left behind.
This robot vacuum does a good job clearing pet hair on low-pile carpet. It can lift away most strands in a single cleaning session, though it tends to leave some behind in the carpet fibers. A small amount of hair gets caught in the brushroll and can be left behind.
The iRobot Roomba i7 has poor airflow performance, even for a robot vacuum. In practice, heavier and lighter debris caught in cracks or crevices prove challenging.
The iRobot Roomba i7 isn't too loud when operating. While you can certainly hear it, it shouldn't be overly distracting unless you're trying to have a conversation right next to it. By contrast, its self-emptying bin gets quite loud, measuring up to 81.3 dBa during the self-emptying operation.
The iRobot Roomba i7 7550 model has excellent maneuverability. It uses iAdapt 3.0 with Visual Navigation to help it navigate and clean a room in an organized pattern, and you can see a map of its coverage area via its companion app. Still, if you're looking for a robot vacuum with a LIDAR mapping sensor for improved low-light maneuverability, the Roborock Q7 Max is a good option. The robot is low enough to get under couches or tables. It doesn't get stuck on rugs or tassels but can drag a light rug around. It can also pull electrical cables.
The iRobot Roomba i7 is effective at sealing in fine allergens. It has an onboard HEPA filter and does a significantly better job of sealing in particles compared to other robot vacuums like the Roborock S7.
This robot vacuum delivers poor performance on cracks and crevices. It has only one power level and can't generate enough suction to lift a lot of fine debris, like baking soda, from deep cracks or crevices.
Without a mopping function, this robot vacuum isn't effective for dealing with stains.
This robot vacuum isn't designed to clean water or liquid spills.
Update 05/26/2021: Changed 'Remote Controller' field from 'No' to 'Yes (App Only)'. The score has been changed.
The iRobot Roomba i7's automation features are decent. You don't need an internet connection to use this vacuum thanks to its physical controls. However, if you want more features, the iRobot Home app allows you to train it to remember the layout of your home. Once you have the map, you can set dedicated cleaning times in specific rooms and create virtual barriers using the map. You can also see its battery life and previous cleaning jobs. You can even empty the bag from the app, as long as the robot is already docked. If it's done cleaning a room, it automatically recharges and empties its bin. It's also compatible with Alexa and Google Home. If you're looking for a robot vacuum with even more automation features, try the Ecovacs DEEBOT OZMO T8 AIVI.
This vacuum is compatible with the iRobot HOME companion app. It allows you to schedule cleaning times for individual rooms and set up virtual boundary markers. The app also shows your previous cleaning history and remaining battery life. It's also fully compatible with Amazon Alexa and Google Home devices, so you can make specific inputs with voice commands.
