The iRobot Roomba E5 is a basic robot vacuum. It does a reasonable job of cleaning bare floors, though it can struggle with pet hair on this surface type and has trouble clearing bulky debris like cereal as its dustbin fills up. Performance on low and high-pile carpet is also only mediocre. Still, it feels well-built, maneuvers itself decently well, and charges very quickly. Unfortunately, there are quite a few parts that need maintenance, and it incurs high recurring costs.
Our Verdict
The iRobot Roomba E5 is an okay choice for cleaning bare floors. It cleans small and bulky debris like rice or cereal easily, though it can struggle with the latter as its dustbin fills up. It also may take an extra pass to fully clean pet hair on this floor type. While its battery life isn't especially long compared to some alternatives, it charges very quickly. It also feels impressively sturdy. Unfortunately, many parts need regular cleaning or replacing.
- Sucks up debris on bare floors when dirt compartment is empty.
- Decently-sized dirt compartment.
- Struggles with pet hair on bare floors.
The iRobot Roomba E5 is passable for low-pile carpet. It has no issue clearing pet hair and sucks up most large debris like sand, but it can have a very hard time with finer material like baking soda. That said, it does have a dirt detection feature that allows it to focus on areas with an especially high concentration of dirt or debris. However, it's worth noting that there are a lot of different parts you need to clean.
- Cleans hair easily on carpet.
- Decently-sized dirt compartment.

The iRobot Roomba E5 isn't a bad option for high-pile carpet. It has no problem cleaning hair on this surface, but it may take another pass to clear larger debris like sand, and it struggles with fine material like baking soda. It automatically adjusts its head height and power suction depending on the surface it's on, enabling it to maneuver on high-pile carpets and rugs. Unfortunately, many parts require regular maintenance or replacement.

Popular Robot Vacuum Comparisons
The iRobot Roomba E5 5150 robot vacuum is fairly basic. It feels well-built, has a HEPA filter, and charges very quickly, but it doesn't offer the same range of automation features as newer alternatives, like the Wyze Robot Vacuum. It also has a harder time clearing debris from carpets compared to pricier models, like the iRobot Roomba S9 or the Neato D8.

The iRobot Roomba E5 is a better vacuum than the iRobot Roomba 694. The E5 clears pet hair much more easily and has a better cleaning performance overall on low-pile carpets. That said, the 694 has a better performance on bare floors, and its battery lasts longer.
The iRobot Roomba E5 is a bit better overall than the iRobot Roomba 675. The two robot vacuums are very similar and have the same features. The E5 performs much better on both low-pile and high-pile carpets and also has a bigger dirt compartment. However, the 675 is a bit better on bare floors, and its battery lasts longer.
The iRobot Roomba i4 is a slightly better vacuum than the iRobot Roomba E5. The i4 does a better job of cleaning bare floors and high-pile carpets, and its suction performance doesn't decrease as much as the dirt compartment fills up. It also follows an efficient cleaning route, whereas the E5 follows a random path. However, the E5 doesn't get caught on rug tassels or electrical cords as easily.
The iRobot Roomba E5 is a better vacuum than the iRobot Roomba 614 for most uses. The E5 clears more pet hair from all surface types, delivers better overall performance on carpets, and works with an app that allows you to schedule cleaning times. On the other hand, the 614 clears more debris from bare surfaces like hardwood or linoleum flooring and has a longer battery life.
Test Results
The iRobot Roomba E5 is impressively well-built. It's made out of a mix of glossy and matte-finish hard plastic, which feels solid for the most part. While its dustbin feels like it could crack if dropped, it's still sturdier than the dirt compartment on other vacuums. There are three buttons on top of its body that allow you to manually start a cleaning session, initiate a spot clean, or return to the dock. There are also light indicators for the battery, Wi-Fi connection, and the status of the vacuum all above the controls.
Out-of-the-box assembly is simple, requiring only that you set up its docking station.
The iRobot E5 has many parts that need to be taken care of. Luckily, they're all easy to access.
- Dirt compartment: The dirt compartment can be removed by pressing the release button on the back side of the vacuum. Once you empty it, you can clean it with water, unlike the iRobot Roomba 675's dustbin, but make sure that it's completely dry before putting it back in place.
- Brushrolls: The rubber brushrolls are easy to take out, requiring only that you remove the brushroll guard. You can remove any tangled hair, but the brushrolls aren't the easiest to put back as you need to align them back in place. iRobot suggests cleaning them once or twice a month, depending on whether or not you have pets.
- HEPA filter: The HEPA filter is located inside the dirt compartment. Since you can't clean it under water, you have to gently tap it on the side of a garbage can to remove any debris. You should clean it once or twice a week, depending on whether or not you have pets.
- Side brush: You need a screwdriver to remove the side brush. You should clean it once or twice a month, depending on whether or not you have pets.
- Front caster wheel: The omnidirectional wheel in front can be removed. You should clean it every two weeks.
- Sensors: The sensors on the vacuum should be cleaned once a month with a dry cloth.
The iRobot Roomba E5 has high recurring costs.
All components can be purchased individually on the manufacturer's website. In addition, there's also a 'Replenishment Kit' that includes three side brushes, an additional pair of rubber brushrolls, and three HEPA filters. If you want a similar vacuum with lower recurring costs, check out the iRobot Roomba 960.
The iRobot E5 has superb storage capabilities. It doesn't take up much space, and it mounts onto the charging dock by itself.
The iRobot E5 has a reasonable dirt compartment. It's relatively large, but unfortunately, it lacks a fill line indicator and is made mostly from opaque plastic, so you can't check its fill status at a glance. iRobot suggests emptying it after each cleaning session, so you don't have to worry about it for the next use. If you want a robot vacuum with a bigger dirt compartment, check out the eufy RoboVac 30C.

The iRobot E5 has an unlimited range as long as it still has sufficient charge and enough room left in its dustbin, but it can't go up or down stairs.
The iRobot Roomba E5 is extremely portable. Unlike the Ecovacs DEEBOT OZMO T8 AIVI, it has a carrying handle for when you need to bring it to another floor.
The iRobot E5 has outstanding battery performance. While its approximately 100-minute runtime is notably shorter than the battery life of alternatives like the Shark IQ Robot, it recharges much faster. In addition, since the vacuum lacks a manual power adjustment feature and instead automatically adjusts its power according to the surface it's cleaning on, the total battery life may change depending on your home's floor type. There's a battery indicator light on top, and it turns red when the battery is low, but it doesn't specify the battery percentage. The mobile app also notifies you when the battery is low.
The iRobot E5 has a few extra features. Its head height automatically changes depending on the surface type that it's on. Its onboard dirt sensor also detects dirtier areas, allowing the vacuum to automatically focus on cleaning on a specific area. However, there's no way to adjust these features manually.
The iRobot Roomba E5 has two removable rubber brushrolls and a side brush that helps push debris into the cleaning path of the robot.
The iRobot Roomba E5 is just okay on bare floors. It struggles with pet hair, but it doesn't have many problems with bulky debris like cereal or small debris like rice when the dirt compartment is empty. However, it quickly loses suction performance as the dirt compartment fills up. In addition, pet hair and some solid debris can sometimes get stuck in the tunnel between the brushroll and the dirt compartment, so when you remove the dirt compartment, the dirt falls out. If you're looking for a robot vacuum with better performance on bare floors, check out the iRobot Roomba 981.
The iRobot Roomba E5 isn't bad on low-pile carpet. It easily cleans hair and does a great job with larger debris like sand. Unfortunately, it's bad with fine debris like baking soda. Thankfully, it doesn't exhibit the same issue with debris and hair getting stuck in the tunnel before the dirt compartment as it does on bare floors.
The iRobot Roomba E5 delivers passable performance on high-pile carpet. It easily clears pet hair and cleans a fair amount of larger debris like sand, though it may need to make another pass to clean it all. It also really struggles with finer debris like baking soda. While it's much better than the iRobot Roomba 675 on this surface type, it doesn't perform as well as the iRobot Roomba i4.
The iRobot E5 has decent maneuverability. The automatic head height adjustment allows it to climb onto high-pile rugs, though it can sometimes drag obstacles like electrical cords. While it doesn't have a smart-pathing feature, it should still manage to cover most of its cleaning area. It's also small enough to move under tables and couches without getting stuck.
The iRobot HOME app has a reasonable selection of automation features. You can pause the vacuum's cleaning progress, schedule cleaning sessions, do a spot clean, ask it to return to the dock, or get notified of the battery status. It's also compatible with Google Home and Alexa, but this isn't something we test for. If you have an unreliable internet connection at home, you can use the buttons on the top of the vacuum to give it commands, without the need for an internet connection or a companion app.
If you want a vacuum with more advanced automation features, take a look at the iRobot Roomba 981.
