Key Differences: Shark ION 720 vs Roomba 690

How different are these two robot vacuum cleaners? Let’s take a look in this section.

Remote Control vs iRobot Home App

The Shark ION 720 comes with a remote control that you can use for scheduled cleaning sessions. To be able to use this remote, you need 2 AAA batteries.

On the other hand, the Roomba 690 doesn’t have a remote. However, it has Wi-Fi connectivity, and you can connect and control it by simply downloading the iRobot Home App.

With the iRobot app, you can also schedule cleaning sessions, and the good this is, you can do this anywhere you are anytime you want. The great advantage of having this app is that you don’t have to wait until you get home before you can command the robot to clean up your floors.

Wall Barrier

Yes, both of these robot vacuums come with a barrier. Why do you need one? Because you may want to clean only a specific room of the house.

What’s the difference? The Shark Ion 720 comes with a 9-foot roll of Botboundary strips. The strips should be cut and placed at the area where you want the vacuum to avoid. The disadvantage of these strips is the cost. Soon, you’ll run out of these barriers and would require a separate purchase.

In comparison, the Roomba 690 comes with a Virtual Wall barrier, which as advertised, has two modes. You can choose between the Virtual Wall and Halo modes depending on your needs. With the Virtual Wall Mode, the device creates a straight-line blockage. With the Halo mode, the device creates a curve-shaped blockage around it.

Weight and Height

There is a significant difference in weight. Which one is heavier? It’s the Roomba 690, which weighs 7.8 pounds, or 2 pounds more than the weight of the Shark ION 720.

Height-wise, there’s also a difference. The Roomba 690 is taller at 3.6 inches. In comparison, the Shark 720 stands 2.6 inches. This one-inch difference can mean a lot especially when you’re targeting under-furniture surfaces.


The Shark Ion 720 comes with 2 spinning side brushes and a self-cleaning brushroll with helix-pattern bristles. It’s worth saying that the main brush has a detangling technology that self-untangles long hair, string, and other particles that can get in the way.

On the other hand, the Roomba 690 has 1 edge-sweeping brush and two main brushes. According to the company, the iRobot is the only brand that has a dual multi-surface brush. One brush is designed to loosen dirt, and the other is to pick the dirt up.
