Neato D8 vs Roomba i3: Differences

After experiencing these two robot vacuums for a while, I conclude that the Neato D8 wins 3:1 and ties 1 against the Roomba i3 thanks to its cleaning performance, navigation technology, and other useful features. For more details, please read the breakdown below.

Cleaning Performance

The winner: Neato D8

Compatible floor types

Overall, both the Neato D8 and Roomba i3 are versatile and can clean a wide range of floor surfaces, including hardwood, tile, laminate, and medium-pile carpet.

In my pick-up tests on hard floors, the Neato D8 performed better. It effectively cleaned up all types of debris, including heavy ones like sand and cat litter, as well as larger debris like Froot Loops.

The Roomba i3 also did a good job handling this kind of debris, but it required more passes to pick up everything due to its weaker suction power compared to the Neato.

The D8 features two cleaning modes: Eco and Turbo. In Turbo mode, the suction power is increased, allowing it to more effectively pick up debris. In contrast, the Roomba i3 only has one suction mode. In return, the i3 is equipped with iRobot’s Dirt Detect technology, which allows it to identify high-traffic areas and clean them more thoroughly. 

For cleaning edges, each machine includes a side brush for more efficiency. The Neato D8’s D-shape design improves edge cleaning compared to round-shape robot vacuums.

As for cleaning carpets, I have noticed that both the Neato D8 and Roomba i3 perform similarly. The Neato D8 boasts impressive suction power but only has one brush roll. On the other hand, the Roomba i3 has two rubber brush rolls that effectively remove dirt and debris from the surface of the carpet and penetrate deep into the fibers.

Pet hair performance

As a pet owner, I highly recommend the Roomba i3 for its dual rubber brush roll that effectively picks up pet hair. Even when dealing with a significant amount of hair, the i3 manages to avoid getting tangled. Moreover, the roller’s design helps minimize hair wrap, making it easy to clean.

The Neato D8 is capable of effectively removing pet hair, but a lot of the picked-up hair gets caught around the bristle brush. Pet hair caught in stiff bristles is also harder to remove compared to rubber rollers. In my opinion, this robot is more suitable for pet owners with short-haired pets.

Design & Usability

The winner: Neato D8

Build quality

When comparing the build quality of the Roomba i3 and the Neato D8 robot vacuums, both devices are designed with a focus on durability and performance.

Starting with the Roomba i3, it boasts a solid build quality with a sleek and compact design. The Roomba i3 is a durable and reliable vacuum that can withstand daily wear and tear. It features a protective bumper that prevents collisions with furniture and other obstacles, as well as a durable dustbin and brush roll to ensure long-lasting use. 

The Neato D8 also offers a well-constructed robot vacuum. Neato devices are known for their D-shaped design, which allows them to reach corners and edges more effectively than round robots. The D8 is designed for durability, with a robust outer shell and a spacious, effortless-to-empty dustbin.

Dimensions and weight

The Neato D8 is designed with a unique D-shaped profile that distinguishes it from the traditional round-shaped robot vacuums. It measures approximately 12.55 inches in width, 13.20 inches in length, and 3.92 inches in height. This D-shaped design allows the D8 to effectively reach and clean edges and corners with precision.

In contrast, the Roomba i3 features a more traditional circular design. The Roomba i3 is designed with a compact and round shape, measuring approximately 13.26 inches in diameter and 3.63 inches in height, which allows it to navigate through tight spaces and fit under furniture with ease.

In terms of weight, the Neato D8 weighs about 8.09 pounds. It is fairly heavy compared with the other robot vacuums I have reviewed before. Conversely, the Roomba i3 is lighter, weighing approximately 7.44 pounds.

The D8’s D-shape design is great for cleaning edges, but it can hinder the device’s movement sometimes. It may get stuck in the same spot multiple times and can’t get out on its own, whereas the Roomba i3 doesn’t encounter this issue.

Battery and charging

The Roomba i3 and Neato D8 both use reliable lithium-ion batteries commonly found in modern electronics. Regarding their battery life, the Roomba i3 can run for up to 75 minutes on a single charge, while the Neato D8 offers a slightly longer battery life of up to 100 minutes. Both models can return to their charging docks and resume cleaning if their batteries run low, ensuring complete coverage.

In terms of charging times, the Roomba i3 typically takes around 2 hours to fully recharge its battery from empty. Meanwhile, the Neato D8 has a slightly longer charging time of approximately 2 to 3 hours.

You can easily charge these two machines using their docking stations that connect to regular electrical outlets. These docking stations are essential for the robots’ independence, as they automatically return to the dock when necessary, ensuring they are always prepared to clean your home.

Noise

My tests show that both machines are pretty quiet, but the Roomba i3 is fairly quieter than the Neato D8. 

The Neato D8 typically produces noise levels between 62 and 71 dB, while the Roomba i3 ranges from 60 to 64 dB. However, these numbers can vary depending on factors such as the cleaning mode and the surface it’s cleaning. Overall, their sound is roughly equivalent to the sound of a normal conversation or background music at a moderate volume.

Navigation and obstacle avoidance

The Neato D8 and the Roomba i3 feature different navigation technologies.

The D8 has the upper hand in this aspect since it employs laser-based LiDAR technology. This allows the D8 to create a detailed and accurate map of your home’s layout. LiDAR sensors emit laser beams to measure distances and detect obstacles, helping the robot build its map while also avoiding collisions.

On the other hand, the Roomba i3 doesn’t employ LiDAR technology. It relies on adaptive software algorithms and a suite of sensors to navigate around obstacles and create a map of your home. Its floor tracking sensor enables the device to move in straight, efficient lines, while the cliff sensors prevent falls down stairs.

Additionally, the Neato D8 has a feature called No-Go Zones, which allows you to draw boxes on the map in the app to keep the robot from going where you don’t want it to go. The Roomba i3 does not support any such features. When it encounters obstacles, it may still collide with the object and then change direction.

Control

The winner: Neato D8

Control

Both machines provide a range of control methods to interact with the robot vacuum.

First, they offer physical buttons on the robot itself, allowing you to start or stop cleaning sessions directly on the device.

For more advanced control, you can control these machines through apps. The Neato smartphone app is available for both iOS and Android users. A standout feature is the ability to set capability zones to designate no-go zones within your home using the app.

The iRobot Home app is available for both iOS and Android and provides extensive control over the i3. It allows you to initiate, schedule, and customize cleaning sessions while offering insights through cleaning reports and notifications.

Additionally, both of them are compatible with popular voice assistants like Amazon Alexa and Google Assistant, enabling you to control the robot using voice commands, which can be particularly convenient.

Cleaning & Maintenance

Tie

Regarding their dirt compartment, the Neato D8 has a larger dustbin with a capacity of 0.7 liters, while the Roomba i3 has a capacity of only about 0.5 liters. The common point is that their dustbins are easy to disassemble, empty, and clean.

The Roomba i3 has a dirt disposal port at the bottom of the dustbin that works with the Clean Base® Automatic Dirt Disposal. Different from the standard docking station, this one includes a huge dirtbag, allowing the robot to empty itself for up to 60 days. However, this is an optional accessory and is sold separately, so you should consider the cost before buying.

In terms of filtration systems, both machines come with HEPA-standard filters with the ability to capture tiny particles, including dust mites, pet dander, pollen, and even some bacteria and viruses. This makes these devices a good choice for households with allergy sufferers or anyone concerned about indoor air quality.

Great For Value

The winner: Roomba i3

From my point of view, the Roomba i3 is more worth the price. Its iAdapt 2.0 navigation system may not use LiDAR, but it still provides reliable cleaning performance with adaptive software algorithms. The iRobot Home app offers extensive control and customization options, making it easy to use. Additionally, the vacuum’s HEPA-type filter helps to improve air quality, and it’s often priced competitively for a robot vacuum from a reliable brand like Roomba.

The Neato D8 is quite expensive for what you get. Its large size and weight can be a hindrance, and the bristle brush roll tends to get tangled often. Nevertheless, it excels in certain areas, such as its utilization of laser-based LiDAR sensors and SLAM technology, which allow for accurate navigation and mapping.
