The Roomba 980, on the other hand, comes with features that are already present in the previous models. In addition, it features the recharge and resume combination, as well as digital cleaning reports and memory mapping. These features alone make this powerful robotic vacuum very autonomous. Like the Shark ION 750, this vacuum automatically returns to its charger when the battery is low and once recharged, it will pick up where it left off, all thanks to the memory mapping technology.

You can also check the digital cleaning report if you want to know if your house has been cleaned or not. Running on Lithium-Ion batteries, this vacuum can operate up to 120 minutes before you need to recharge it.

Overall, the Roomba 980 proves to be the better option compared to the Shark ION 750 in terms of cleaning effectiveness. If you have the budget for it, then you should consider buying the Roomba 980.

When it comes to size, the Shark ION 750 has a smaller dimension and is more lightweight than the Roomba 890. For the filtration system, the Shark ION 750 uses the HEPA filtration while Roomba 890 uses AeroVac High-Efficiency filtration. For navigation, the Shark ION 750 comes with the Smart Sensor Navigation while the Roomba 890 comes with the iAdapt Navigation system.

Another point of comparison between these two outstanding vacuum models is that the Shark ION 750 is equipped with two side brushes when Roomba 890 has only one side brush. The recharge time for the Shark ION 750 was estimated to be an hour longer than that of the Roomba 890. In addition, The Roomba 890 has a full bin indicator, unlike the Shark ION 750. Lastly, the Shark vacuum comes with a full-width brush bar while the Roomba 890 comes with dual brushless extractors.

Overall, the Roomba 890 proves to be more effective in cleaning any type of floor. While the Shark ION 750 is way cheaper, you might want to give this one a second thought because reviews claimed that this vacuum tends to be challenging to operate on carpets.


The Shark ION 750 has the capability to return to its charger when the battery is already running out of juice. To add, you can also create a timetable for its cleaning schedule. Running on Lithium-Ion batteries, this vacuum can operate for up to 60 minutes before you need to recharge it. However, it is also noteworthy that it may still need supervision because it may get stuck on obstacles, unlike the Roomba 980.

Both the Shark ION 750 and the Roomba 690 have Wi-Fi capabilities, has a remote control via their respective mobile applications, as well as the same battery life of one hour. However, they do have differences. The Roomba 690 uses AeroVac filtration while Shark ION 750 uses HEPA filtration, which has proven to be a lot more effective in capturing small dirt and dust particles.

Another point of comparison between the two is the virtual wall feature of the Roomba 690. This technology produces the light, which is only visible to the unit. This boundary can block an area of up to 10 feet long, which also comes with an on and off switch. To add, you can turn on the Halo mode, especially if you want to block a 4-feet long diameter in your home.

While the similarities are very apparent between these two units, you should also consider both of their maintenance costs. The Roomba 690 has been proven to be a lot more economic than the Shark ION 750, even though they have the same price on the market.
