The Botvac D7 Connected is the latest vacuum robot by Neato Robotics. Knowing that Neato is the the second best cleaning robots maker, we expect the Botvac D7 to be the best robotic vacuum cleaner for 2018. In this review we present the D7 main features and compare it to the maket leader: the Roomba 980 by iRobot.

Overview of the Two Best High-End Vacuum Robots on the MarketWe start with an overview of the Roomba 980 and the Neato D7 thanks to our selection of videos. They provide you with main features of the two best high-end robotic vacuums. You can however skip them, and read our detailed comparison. Alternatively, you can jump to our conclusion that provides you with our recommendation.
Roomba 980: The Market Leader
Neato Botvac D7 Connected: The Challenger
Cleaning PerformanceBoth vacuum robots have a composite cleaning system. On the one hand, a set of brushes collect dirt and debris around and below the robot. On the other hand, a vacuum pump sucks hair and dust. However, the Roomba and the Botvac have different designs that we discuss below. We also analyze and compare their cleaning performance.
Brushes Layout and Corner CleaningThe D7 includes many nice features that make Neato Robotics’s vacuum robots the most serious challengers of the mighty Roomba. First, there is the patented D-shape. It allows the main brush get closer to the wall, as opposed to the round Roomba. Figure 1 shows the lower sides of the Roomba 980 and the Neato Botvac D7, exposing their brushes. Walls are colored in orange. The area cleaned by the Roomba 980 is red, while the one covered by the Botvac D7 is green.
Suction Power and Noise LevelAs for traditional vacuums, suction power is critical to vacuum robots cleaning performance. However, robot designers face a challenge here. Vacuum robots are cordless, and rely on a battery. More suction power means draining the battery more quickly. However, both Roomba 980 and Neato D7 Connected are supposed to operate 120 minutes on a single charge. So, there is definitely a tread-off between power consumption and how long does the battery last. Another important factor related to suction power is the noise level. Increasing suction means increasing noise. Actually, noise is also, generated by rotating brushes. To deal with both with the battery constraints and the noise level, Roomba 980 and Neato D7 have two energy/noise level modes: Turbo mode and Eco mode. In Turbo mode, they operate at full power. This means maximum cleaning performance, but at a cost of maximum noise and shorter battery run-time. In Eco mode, the two vacuums consume less lower and make less noise. But, the cleaning is not as good as in the Turbo mode. Having said that, let’s have a look on the actual figures of both robots.
|Suction (The Higher the Better)||Roomba 980||Neato Botvac D7|
|Turbo Mode||669 ft/min||767 ft/min|
|Eco Mode||453 ft/min||649 ft/min|
|Noise Level (The Lower the Better)||Roomba 980||Neato Botvac D7|
|Turbo Mode||78 db||70 db|
|Eco Mode||69 db||66.5 db|
Bumping Into Furniture vs. Systematic CleaningHaving robot autonomously navigate and clean different homes is really challenging. Each home has its own configuration. Rooms, walls, doors, and furniture are different in number, place, shape and size. Not mentioning toys, pet bows or other objects on the floor. To deal with this complexity, early Roombas relied on random navigation. Basically, it moves in a straight line until bumping into an obstacle. It rotates away at a random angle. This process is repeated for some time. The resulting behavior looks anarchic and definitely unnatural. But, eventually the Roomba does clean the full floor.
Mapping the Floor for Systematic Cleaning Pioneered by NeatoFrom its inception, Neato took the more ambitious road to perform systematic cleaning. It requires having a map of the floor. This is why all Neato robotic vacuums have a 360 degrees laser range sensor onboard (see Figure 3). This laser scanner is capable of precisely measuring the distance between the robot and all obstacles. Thanks to a SLAM algorithm, the Neato turns distances to obstacles into a map (see Figure 4).
Roomba 980 Camera-Based Systematic CleaningAfter several years of relying on the robust though old random navigation, Roomba 900 series switched to systematic cleaning. They rely on a camera oriented 45 degrees towards the ceiling (see Figure 5). Based on pictures collected by this camera, the Roomba 980 is capable to locate itself and detect most obstacles. The 980 can then map your home and clean it in a systematic fashion just like like the D7.
Camera-based vs Laser-based Mapping and Systematic CleaningAlthough both robotic vacuums are capable of systematic mapping, there are some differences. Each manufacturer did chose a different technology with its pros and cons. Neato D7 relies on a laser range sensor located on top of the robot. This means that the D7 is slightly thicker than the Roomba 980. The Roomba can go under some furniture that might be to low for th Botvac D7. However, the D7 can map a totally dark place, while the 980 won’t. Indeed, the 980’s camera requires some light to operate properly. The Roomba will still be able to do the cleaning, but in a degraded mode. Another advantage of the Neato over the Roomba, is that D7 has persistent maps. The Roomba 980 has to reconstruct a map upon each cleaning cycle. While, the D7 builds the map only the first time it operates, and then stores it for future cleaning sessions. Beside speeding up the cleaning a bit, this persistence allows setting No-Go lines, presented below.
Telling Your Robot Where to Clean
Roomba’s Virtual Wall BarriersTo restrict cleaned areas, the Roomba 980 is shipped with two Virtual Wall Barriers. The Roomba bounces away when it perceives the infra-red light emitted by those two little pillar-shaped devices. A virtual wall barrier operates on battery, and has two modes. In Virtual Wall Mode, it blocks openings of up to 10 feet, keeping Roomba in the rooms you want cleaned and out of the ones you don’t. In Halo Mode, it creates a 4-foot diameter keep out zone around items you want to protect.
Neato’s Boundary MarkerWith the D7, you get a roll with an 8 feet long boundary marker. This marker is a thin passive magnetic strip. You can cut it in many parts to fit the width of doors or the length of areas you want to restrict. All Neato vacuum robots embed a magnetic sensor. So, the Botvac D7 turns away, whenever it runs into a boudary marker. Since the boundary marker is magnetic, it is battery free. Just set it and forget it. It requires no maintenance, and no waste. Thus, it makes the BotVac more eco-friendly than the Roomba.
Neato Botvac D7 Virtual No-Go LinesVirtual No-Go Lines is one of the novelties of the D7 (see Video 2 above). This unique feature is a digital complement to the boundary marker. It combines Neato’s mobile app with the ability of the Botvac D7 to finely localize itself within your home. It’s very simple to use. All you have to do is to open the Neato’s app on your smartphone. Then, draw Virtual No-Go Lines around places you want your Neato Botvac to avoid. Those can be pet bowls or a pile of toys. Your robot knows where to go to avoid getting stuck.
Customer ServiceThe quality of customer service is an important criterion when choosing a robotic vacuum. However, this criterion is not specific to one robot. It instead measures how good is the brand at serving its customers. In our review of vacuum robot brands, we had collected user overall satisfaction for 39 robotic vacuum cleaners from 12 different brands. Each of the 9515 users who responded provided a score between 1 and 5 that rates their experience with the vacuum robot and the customer service of the manufacturer. It turns out that iRobot (the Roomba maker) offers a better customer service compared to Neato Robotics. Indeed, in our brand comparison, iRobot ranked 1st, with a score of 4.1 out of 5. Neato comes 2nd with a score of 3.9 out of 5.

Conclusion & Recommendation
The Roomba 980 and the Neato Botvac D7 Connected are both high-end vacuum robots, by the two best vacuum robot brands. Both robots have very good build quality. They both achieve very good cleaning performance for all kinds of floors. They are also very good at picking hair and cleaning carpets. Having said that, the Neato Botvac D7 Connected is superior to the Roomba 980 featurewise as summarized by Table 4 and Video 4 below. However, from the customer service perspective, the Roomba 980 is the best vacuum robot.
