The iRobot Roomba i1 is an entry-level model in iRobot's lineup of smart-pathing i-series robot vacuums. It's effectively a retailer-specific variant of the iRobot Roomba i3 that's generally only available at Kohl's and Walmart locations. While both vacuums are mechanically identical, the i1 has a less advanced set of automation features, with no support for imprint smart mapping functionality that would allow you to set up virtual boundary lines or label specific rooms. That said, it feels reasonably well-built, offers fantastic battery performance, and does a pretty good job of maneuvering itself.
The iRobot Roomba i1 is okay for bare floors. It does a good job of handling small debris and pet hair on this surface type, though moderately large amounts of bulky debris are likely to clog its dirt compartment. Thankfully, it's easy to maintain, thanks to its self-emptying capability, which ensures that you don't have to empty its dirt compartment manually if you buy it with its self-emptying station. It does a good job of maneuvering itself, though its lack of smart pathing functionality means you can't set virtual boundary lines or schedule cleaning sessions for specific rooms.
The iRobot Roomba i1 is a passable option for low-pile carpet. It has a hard time with fine material as well as pet hair on this surface type. Thankfully, it does a pretty good job of maneuvering itself on carpeted floors and is pretty easy to maintain, especially if you buy it with a self-emptying base station. However, buying it with the base station does mean higher recurring costs, as you'll need to swap in a new dirtbag periodically.
The iRobot Roomba i1 isn't bad for dealing with messes on high-pile carpet. It's reasonably effective in clearing away pet hair and larger debris on this surface type but has a hard time lifting away finer material. Thankfully, it offers fantastic battery performance, and unlike a lot of other entry-level robot vacuums, can resume a cleaning session from where it left off if it needed to return to its docking station to recharge.
The iRobot Roomba i1 is a solid option for dealing with pet hair on floors. It's pretty effective in dealing with this debris type on bare floors and high-pile carpet, but struggles with clearing it away on low-pile carpet. User maintenance is simple, with its twin rubber brushrolls being very easy to remove and clean. Its high-efficiency filter is also very effective in trapping allergens like pet dander. Unfortunately, its motor emits a somewhat disruptive noise, and it lacks any mopping feature to deal with dried-on dirt.
The iRobot Roomba i1 is a robot vacuum and isn't suitable for cleaning stairs.
The iRobot Roomba i1 is a robot vacuum and isn't designed to clean the inside of your car.
The iRobot Roomba i1 isn't designed for workshop cleaning.
There are two variants of the iRobot i1: the basic variant, referred to as the i1, and the i1+, which comes bundled with a self-emptying docking station. We tested the i1+ variant, and you can see its label here. That said, both vacuums are mechanically identical and will deliver similar overall cleaning performance, though the inclusion of the auto-empty dock does reduce hands-on maintenance requirements. If desired, you can buy a basic i1 and purchase the i-series Clean Base Automatic Dirt Disposal docking station.
If someone comes across a differently-equipped variant of this vacuum, let us know in the discussions, and we'll update our review.
The iRobot Roomba i1 is an entry-level smart-pathing robot vacuum that's fully compatible with a self-emptying base station. It's almost identical in design to the iRobot Roomba i3, the main difference between the two being that the i3 can generate a permanent map of its coverage area, which you can use to set specific cleaning settings for different rooms and set up virtual boundary lines. Unfortunately, it carries over a lot of the i3's weaknesses, with poor overall debris pickup performance on carpeted floors. It also struggles with bulkier debris, which can clog the entrance to its dustbin.

The iRobot Roomba i3 is a little better than the iRobot Roomba i1, though it's worth mentioning that the two vacuums are mechanically identical, with the i1 being a retailer-specific variant of the i3. Following a firmware update, the i3 received support for imprint smart mapping, which allows you to set up virtual boundary lines or label specific rooms.
The iRobot Roomba i1 is better than the iRobot Roomba 694. The i1 is easier to maintain, does a better job handling pet hair, and offers a more comprehensive suite of automation features, including smart pathing and full compatibility with self-emptying base stations. The i1 also does a much better job of sealing in fine particles. Conversely, the 694 doesn't struggle as much with bulky debris, thanks to a beater brush that crushes larger debris before it gets sucked up.
The Shark EZ Robot Self-Empty and iRobot Roomba i1 each have their strengths, meaning one might suit you better than the other, depending on your needs. The Shark incurs lower ownership costs, as its self-emptying base station doesn't use disposable dirtbags. The Shark also struggles less with bulky debris. However, the iRobot's self-emptying base station has a greater debris capacity. The iRobot is also easier to maintain, takes much less time to recharge, and has a more intuitive companion app.
The iRobot Roomba j7 is better than the iRobot Roomba i1. The j7 has a hazard recognition system that enables it to spot and avoid obstacles like pet waste in real time, meaning you don't need to worry about making sure your home is completely free of obstructions before letting it run. It also feels better built, does a better job of maneuvering itself, and is quieter.
This vacuum feels pretty well-built, though build quality does fall slightly short of higher-end iRobot models with a hollow-feeling housing. Otherwise, it's pretty similar to the iRobot standard, with dense rubber brushrolls, a three-armed side brush, and a centrally-mounted caster wheel. It has a top cover made of matte-finish bronze-colored plastic, which differs from the iRobot Roomba i3, which has a plastic top cover textured to look like fabric. There are three buttons on top of the robot: a big center one to start and stop a cleaning cycle, and two smaller buttons to send the vacuum home and have it spot-clean an area.
The vacuum comes pre-assembled, so all you need to do is set up the docking station, which arrives with a dirtbag already inside.
This vacuum is pretty easy to maintain.
Any part you can wash under water should be allowed to dry for 24 hours before putting it back in the vacuum.
The iRobot i1 Plus incurs high recurring costs.
iRobot sells a 'Replenishment Kit' that contains three side brushes, a new pair of multi-floor rubber brushrolls, and three HEPA filters.
The iRobot i1+ is pretty easy to store. Its base station is taller than that of the j7 variant of the iRobot Roomba j7 but has a similar horizontal footprint and is consequently easy to fit in a small nook. You can wrap up any excess length of power cord behind the base station.
The iRobot Roomba i1+ can hold an impressive amount of debris. The external dirt compartment's capacity of almost two and a half liters is similar to a lot of full-size bagged canister or upright vacuums like the Miele Classic C1. An indicator light on the station lets you know when the bag is full or if there's an obstruction in the tunnel leading toward the bag. The app can notify you when the dirt compartment or bag is full.
This vacuum's range is limited only by its remaining battery life, but it can't go up or down stairs.
This vacuum is quite portable. It weighs a little less than the iRobot Roomba i8+, but unlike the latter, it doesn't have an integrated carrying handle that would make it easier to pick up and carry around.
This vacuum has superb battery performance. It can run for about two hours on a full charge, though since it automatically adjusts its suction power in the presence of high concentrations of debris, its runtime won't be quite as long if it's cleaning a very dirty area. It can fully recharge in under 100 minutes, which is very fast by the standards of other robot vacuums. You can keep an eye on the vacuum's current charge level by monitoring the indicator light around the 'Clean' touch-sensitive button, which switches from solid white to solid red as the charge level drops.
This vacuum has a few quality-of-life features. Like the iRobot Roomba i8+, it focuses on cleaning areas with a higher concentration of debris. However, you can't adjust its suction power manually.
This vacuum has a single side brush that moves debris from the outside edges of the vacuum into the path of its main brushroll.
The iRobot Roomba i1 has middling performance on bare floors. It has no trouble dealing with smaller debris like rice, but any moderately large pile of bulkier debris will block the entrance to its dustbin.
Note: All testing was completed when the dirt compartment was empty, with the data for the 0.25L, 0.75L, and 1.5L tests being copied from the 0L test. Since this vacuum automatically empties its internal dirt compartment when docked, it doesn't lose suction performance as its internal dustbin fills up.
This vacuum does a poor job of dealing with debris on low-pile carpet. It clears away a reasonable amount of larger debris like sand, though a second or third pass might still be necessary to get everything. It has a very hard time clearing away fine material like baking soda on this surface.

This vacuum does a good job of dealing with pet hair, with a few caveats. It doesn't have much trouble dealing with hair on bare floors or high-pile carpet, but it'll take a few passes to fully clear away this kind of debris on low-pile carpet.
The iRobot Roomba i1's real-world suction performance is poor. Like most other robot vacuums, its suction inlet is positioned too high above the contact surface to create a tight seal, so real-world suction measurements are low.
This vacuum isn't too loud. However, it emits a somewhat odd noise that almost sounds as though its motor is failing, which could be quite disruptive.
The iRobot Roomba i1 has good maneuverability. While it doesn't store a permanent map of its coverage area, it still relies on smart pathing to navigate, and as a result, it cleans in an organized pattern. Unfortunately, it can have a bit of trouble navigating around obstacles like chair legs or coat stands. It also has quite a bit of trouble climbing onto shag pile rugs and gets stuck on loose obstructions like rug tassels. Thankfully, the lack of a LIDAR sensor and its compact dimensions allow it to clean under most couches and chairs without too much difficulty.
This vacuum does a great job of sealing in fine allergens thanks to its onboard high-efficiency filter.
This vacuum does a terrible job of clearing away debris in cracks and crevices. Like a lot of lower-end robot vacuums with less powerful motors, it doesn't exert enough suction force to draw out debris from deeper crevices, and its side brush is ineffective in helping to dislodge debris.
The iRobot Roomba i1 does a terrible job of dealing with dried-on stains. Unlike the Roborock E4, it isn't compatible with a mopping attachment for scrubbing away stains.
The iRobot i1 has excellent automation features. Its 'Recharge and Resume' capability lets it resume a cleaning job from where it left off after returning to its docking station to empty its dustbin or recharge. You can also control certain functions with the trio of physical buttons on its top cover. The 'Home' button has it return to the base station, the 'Power/Clean' button turns it on and off and has it start a cleaning session, and the 'Spot Clean' button tells it to clean a small area. It's also fully compatible with Google Home and Amazon Alexa devices, which allow you to make specific commands using your voice.
The iRobot i1 has a good set of in-app features. You can use it to schedule cleaning sessions for your home while you're away, check the 'Product Health' tab to see the replacement time for its filter, side brush, and brushrolls, and enable or disable various user and safety settings, like a child and pet lock. While the vacuum doesn't store a permanent map of your home, you can still see the coverage map it generates at the end of a cleaning session. However, unlike the iRobot Roomba i3, which received a substantial firmware update, you can't label rooms, add area dividers, or set custom cleaning settings for specific rooms.
