Face to face model comparison

Design and Aesthetics The design of a robot vacuum is an important consideration when looking for the best robot vacuum to buy. Aim at a low-profile Roomba that can go under low-profile household fittings such as sofas, coffee tables, and kickstands, among others. It should also go between tight spaces without any restrictions. So, how does the Roomba i3 compare to the j7 in terms of design and aesthetics?
Round-shaped design
iroomba i3 Design

The Roomba i3 may not be the slimmest robot vacuum we have tested, but it has a low-profile design. It has a 13.26-inches diameter and stands at 3.63-inches high.

Weighing 7.44lbs, the i3 is available in a single color, black, and grey, with a woven-textured top interface.

Round-shaped design
Roomba J7 Design

The Roomba j7 is also round-shaped and has a low profile design too. Regarding the dimensions, the j7 and j7+ are 13.3-inches in diameter and stand at 3.4-inches.

As for the weight, the J7 is 7.49lbs. Last, on the finish, the j7 and j7+ come in a single finish, black, and silver.

Cleaning Orientation Robot vacuums are highly specialized. For example, there are robot vacuums that can vacuum and mop simultaneously. Besides, there are robot vacuums for hardwood floors, carpets, pet hair, large apartments, etc. So, how does the Roomba i3 compare to the j7?
Vacuum-Only
iroomba i3 Cleaning Orientation

The Roomba i3 is a robot vacuum with a vacuuming function only just like all other Roombas. For mopping, you will have to invest in a separate robot mop, preferably the Braava M6.

The good thing is that it can sync with the Braava M6 for simultaneous vacuuming and mopping. As for specialty, the i3 and i3+ are designed for all bare floors and low pile carpets. The two are also ideal for homes with pets.

Vacuum-Only

The j7 is also a vacuum-only Roomba, but it can work with the Braava M6 for simultaneous vacuuming and mopping. This is courtesy of Imprint Link Technology.

When it comes to specialization, the j7 and j7+ are ideal for homes with all types of bare floors, including hardwood. You can also rely on this Roomba to vacuum low pile carpets and pet messes such as kitty litter and pet hair.

Vacuuming Performance The vacuuming performance of a robot vacuum can be the deal maker or breaker. In this section, we will assess two important components of a robot vacuum with regards to vacuuming performance. First is the suction power, and second, the brush system.
900pa
iroomba i3 Vacuuming Performance

The Roomba i3 uses Roomba’s patented AeroForce 3-stage cleaning system. There is a dual multisurface brush system for dirt agitation and dirt pickup.

It is assisted by a single sweeping brush that reaches the deep corners and wall edges. Regarding suction power, the Roomba i3 uses a 2nd Gen motor that delivers an average of 900pa.

iroomba i7 Vacuuming Performance

The Roomba j7 and j7+ are similar to the i3 and i3+. The two also use the AeroForce 3-stage cleaning system. There is a dual multisurface brush system and a side sweeping brush.

In terms of suction power, the j7 also puts up an average of 900pa courtesy of the 2nd Gen motor.

Filtration The last thing to consider when buying a Roomba is the filtration. Here, we will assess the kind of filters used. Without further ado, let's get into it.
High-efficiency filters
iroomba i3 Filtration

Just like all other Roombas, the i3 and i3+ come with high-efficiency filters that capture 99.9% of allergens and other elements that can trigger allergies or cause bad odor. For the record, these are not true HEPA filters, but they still get the job done.

High-efficiency filters
iroomba j7 Filtration

The Roomba j7 is similar to the Roomba i3 in terms of filtration and bin emptying. Here again, there are high-efficiency filters that capture all kinds of allergens, including pollen, dust mites, and pet-related dander.

Bin Emptying The last thing to consider when buying a Roomba is the bin system. Here, we will assess the bin capacity and bin emptying.
0.5L

When it comes to the bin, there is a 0.5L onboard bin with a full bin indicator. Regarding bin emptying, the two are compatible with iRobot’s Clean Base Automatic Dirt Disposal Technology.

However, only the i3+ comes with the Clean Base® Automatic Dirt Disposal unit.

0.5L

The bin here also has a 0.5L capacity and a full bin indicator.

As one of the latest Roombas, the j7 supports automatic self-emptying, but only the ceiling model, the j7+, comes with the Clean Base® Automatic Dirt Disposal Technology.

Battery and Runtime When buying a robot vacuum, the battery is an important consideration as it determines the runtime of the robot and, consequently, the area it can clean on a single charge. Here, aim for a robot vacuum with a high capacity battery and smart power management. So, how does the Roomba i3 compare to the J7?
1800mAh / 75 minutes
iroomba i3 Runtime

The Roomba i3 and i3+ come equipped with a 1800mAh lithium-ion battery that offers 75 minutes runtime on average.

Regarding power management, the two Roombas will dock for recharge automatically and resume cleaning after that. The recharge time is around 2-3 hours.

2210mAh / 90 minutes
iroomba j7 Runtime

One of the differences between the Roomba i3 vs. j7 is the battery and runtime. While the i3 comes with a 1800mAh battery, the j7 and j7+ come with a larger Roomba® i8 Denali 2210mAh battery that offers 90 minutes runtime.

The only thing the i3 and j7 share is power management. The j7 and j7+ will also recharge and resume cleaning automatically. Recharge time is also 2-3 hours.

Navigation System Navigation is all about how the robot vacuum finds its way around your house, and importantly, how it avoids obstacles.
iAdapt 1.0
iroomba i3 Navigation System

While it may be a pretty new model, the Roomba i3 uses an old navigation system dubbed iRobot iAdapt 1.0. This is a technology that uses a Simultaneous Localization and Mapping (SLAM) algorithm to enable the robot to locate where it is and, importantly, avoid accidents.

There is a set of obstacle detection sensors for localization and, notably, obstacle avoidance. There is also a retractable bumper that retracts to absorb impact if the Roomba hits an obstacle.

Besides obstacle detection sensors, there are also anti-drop sensors that prevent the Roomba from falling off the stairs.

iAdapt 3.0
iroomba j7 Navigation System

The Roomba j7 comes with an advanced navigation system dubbed iAdapt 3.0. This system relies on Visual Simultaneous Localization and Mapping (VSLAM) algorithms for localization.

iAdapt 3.0 uses both sensors and a real-time camera for precise navigation.

Interestingly, there is what is called PrecisionVision Navigation which enables the robot to identify common traffic such as dog poop, shoes, power cords, socks, and so on.

Mapping System Besides navigation, mapping is also an important consideration when choosing the best Roomba for you. Mapping is all about how the robot vacuum understands your home's layout. If you have a large apartment with multi-levels and multi rooms, mapping is a major concern. So how do the two compare?
No mapping
iroomba i3

The Roomba i3 is an entry-level Roomba that doesn’t come with mapping features. Instead, it uses floor tracking sensors to map your home.

When it comes to the cleaning pattern, the i3 cleans in neat rows guaranteeing entire level cleaning in small to medium-sized apartments, but in large apartments, it may skip some spots. The Roomba i3 doesn’t come with any extras such as Keep Out Zones.

Imprint Smart Mapping
iroomba j3 Imprint Smart Mapping

Unlike the Roomba i3, the J7 comes with an intelligent mapping system called Imprint Smart Mapping. This technology enables the Roomba to learn, map, and adapt to your home’s layout by creating accurate maps of your home.

For example, you can tell the Roomba to vacuum specific rooms instead of the entire house. What’s more? The Roomba j7 has digital boundaries dubbed Keep Out Zones. You can easily create boundaries right from the mobile app.

Smart Features and Convenience In this smart home era, you definitely want a smart home-ready Roomba with intelligent features. So, how does the i3 compare to the j7?
