At a glance The quick answer The Roomba i6+ and Roomba 981 both boast good suction capabilities compared to the previous product line of the brand. They also make use of infrared and visual sensors to navigate through the house. However, the Roomba i6+ has a much better advantage in terms of hardware since it is able to Keep Out Zones and Smart Mapping which allows better control of the device. Not only that, but you also get greater value in terms of the Self-Disposal Mechanism which fully eliminates the need for human intervention. Basically, the Roomba i6+ has all the features of the Roomba 981 plus the added benefits of several software enhancements. If you are an owner with a large home who also needs more functionality, then the Roomba i6+. Bear in mind that the Roomba i6+ is a few hundred dollars more expensive than the Roomba 981, which makes it a bit discouraging for new robot vacuum owners. If you want to get a vacuum with equally great hardware and software, then the victor is the Roomba i6+.

It is currently considered one of the best robot vacuums in the market due to its efficiency in cleaning.

The same can be said for the Roomba 981 and Roomba i6+ as they both boast 10x more power lifting suction compared to traditional models. Furthermore, this power is complemented by a 3-stage cleaning system to ensure that nothing escapes the grasps of the robot. This makes picking up dirt, debris, gunk, or pet hair on all floor types very easy and gives the house a thorough clean. Logical Cleaning Pattern Both the Roomba i6+ and Roomba 981 do not clean the room in randomized patterns. Instead, they use logical cleaning through the Neat Rows system to navigate the entire room. Neat Rows allow the devices to make use of their sensors so that they can identify and locate the most efficient cleaning session routes. This way, any owner will be guaranteed that no spot will be missed during the entire process. A Logical Cleaning Pattern also ensures that commonly neglected spots such as wall and floor edges as well as regions under furniture are taken care of. Smart Home Enabled Another great feature of these Roomba vacuum cleaners is that they have wifi connectivity and can be integrated into Alexa and Google. This allows for voice control and long-distance commands even if you are not in the vicinity. You can even set-up scheduled cleaning for better time management! Safe From Allergens The Roomba i6+ and Roomba 981 have a HEPA filter that can block allergens and dust that can not be seen by the naked eye. This makes them great for homes with pets that shed heavily. Not only that, but the great powerlifting suction also picks up pet hair and irritants that can not be seen by the naked eye and the allergenlock technology keeps odors locked away. This ensures 100% protection even when disposing of the contents of the robot since no hazards will escape the filters. Recharge and Resume Operations of the Roomba i6+ and Roomba 981 are smooth and seamless. Both products have heavy-duty batteries which provide a long runtime and helps them provide an interrupted cleaning process. Once their energy gets depleted, they have the ability to self-dock and return to the charging station and regain battery levels. This recharge and resume process ensures that there is no downtime during cleaning. Both robot vacuums are also capable of locating where they left-off due to their memory. Multi-stage cleaning The Roomba i6+ and Roomba 981\u2019s Multi-stage cleaning ensures that every nook and cranny of your home is taken care of. They have dual rubber brushes that do not get tangled with a pet or human hair, making them great for vacuuming anywhere. They work well with rugs and carpet thanks to carpet boost mode. The vertical clearances are designed to stay in contact with the floor so that even hardwood and concrete floor surfaces are dealt with. App-integration Most of the advanced controls of the robot vacuum can be accessed through your smartphone with the iRobot Home app. It provides unique cleaning suggestions that are based on your robot\u2019s cleaning habits. You can even set scheduling, see reports on the whole process as well as terminate operations instantly even if you are not in your home. The app can be downloaded on both iOS and Android phones. Key Differences In this part, we will look at the major variations between the Roomba i6+ vs Roomba 981. Smart Home Mapping This can be considered as one of the greatest differences between the Roomba i6+ and Roomba 981. In comparison, the Roomba i6+ is Smart Home Mapping-ready, meaning that it is capable of creating floor plans and layout of your home based on its visual sensors. This allows the user to assign labels to any room and command the robot vacuum to go to specific spots. It also remembers the floor plan so that there is no need to gain information on the next clean. On the other hand, the Roomba 981 is only capable of absorbing information based on its sensors. This means that it can not map the layout of a house, let alone keep it for future reference. Despite this, it still has good software that allows logical cleaning. Keep Out Zones Restriction zones are a must-have for any advanced robot vacuum cleaner. The Roomba i6+, thanks to its advanced software, has a Keep out Zone system that allows a user to select points in the house where the robot vacuum should not go to. Using the layout created by the Smart Home Mapping, you can draw squares on the region where you want it to stay away from. This provides better control and efficiency. This feature does not exist in the Roomba 981, as the only way to restrict it from entering another area is through the purchase of additional virtual barriers. The Roomba i6+ eliminates this need, making it a more superior robot vacuum. Self-Disposal The iRobot Roomba i6+ completely removes the need for human presence thanks to its self-emptying mechanism. There is no need for the owner to take out the bin after every clean as the robot vacuum does it for you. The Roomba i6+\u2019s Automatic Dirt Disposal System is able to store dirt for up to 60 days, making it less taxing to maintain. Pair this clean base feature with the self-charging capability, and you got a very smart and reliable robot vacuum that does everything by itself. The iRobot Roomba 981 does not have this feature, and there is a need to get the contents of the bin out every two cleaning cycles or less. However, this depends on your floor size, as well as how clean it is. Overall, the iRobot Roomba i6+ does the same job as the iRobot Roomba 981 in a better and more efficient way. Bin Capacity The dust bin capacity of the iRobot Roomba i6+ is 0.7L. This enables it to have a run time fit for more than 3 cycles without the need for emptying. In such cases where the bin is full, the robot vacuum proceeds to self-emptying using the Automatic Dirt Disposal Dock. On the other hand, the Roomba 981\u2019s capacity is only at 0.5 L which equals about 2 cycles. Once it is full, there will be a need to remove the bin by yourself and dump the contents into the trash. Furthermore, the bin of the iRobot Roomba i6+ is washable while 981\u2019s is not. This makes the former a bit easier to maintain. iAdapt Navigation Technology The navigation software of the iRobot Roomba 981 was what made it a very formidable force in the robot vacuum cleaner industry. It used both vSLAM and iAdapt 2.0 to determine its next actions, as well as to locate an efficient cleaning path. This was further improved in the iRobot Roomba i6+, as the device used the new iAdapt 3.0 version. This meant better sensing capabilities which enable it to detect the presence of dirt. Price The iRobot Roomba i6+ is at a higher price point due to its added features. If you're not too fussed about the self-emptying clean base, you can get the vacuum only which will save you some money. On the other hand, as the older model, the Roomba 981 retails for less and can often be found in discount sales.
