Battery Life

In terms of battery, both models have lithium-ion ones that offer you a one-hour running time on a charge. The batteries are more durable as well.

However, for some reason, it takes longer for the Ion 750 to charge its batteries, taking about three full hours. Its counterpart only needs two hours to charge. When the battery dies, the robots return to the docks by themselves to recharge, meaning that you won’t have to worry that you’ll forget to recharge them yourself.

Still, they won’t automatically resume cleaning once they’re charged, so you will have to do that manually or wait until the next schedule comes up.


The Roomba 890 has some acoustic and optical sensors through which it can find areas that require more cleaning, thus focusing on them more. Moreover, these are the ones preventing the machine from hitting any obstacle, falling down the stairs or bumping into walls.

In addition, the apps allow you to see status reports, mark areas for spot cleaning and even give the Roomba robot a name if you want to.

Spot Cleaning

From time to time, you might have one area of the floor dirtier than the other, requiring more time to clean. Thankfully, these robot vacuums are not only useful for creating a path and cleaning everything on it. They also come with the spot cleaning feature. It is a special mode that makes the robot clean a certain spot depending on your commands. Therefore, it can focus on that one annoying area that you can’t stop thinking about.

So, you select it, and the robot will activate to clean a specific area. The cleaning will be deeper than normal while the vacuum will spin in an ever-growing circular pattern.

Once they’re done with that spot, they will either resume the cleaning circle they were on when you activated spot mode or return to the dock. The difference between the two is that the 750 makes three passes in an ever-widening circular pattern and resume. At the same time, Roomba uses the dirt detection sensors to make sure the area is clean before it moves on.

As such, if you suffer from asthma or allergies, dust won’t be a problem for you anymore, as the filters prevent it from entering the air.


When it comes to the dustbin, you’ll know when it’s full on the Roomba 890, as it has an indicator that shows you this. Therefore, you won’t have to keep checking it to ensure it’s not full. However, the Ion 750 doesn’t have this feature, meaning that you have to empty the dustbin after each cleaning session.

Thankfully, it’s not hard to remove the dustbins or replace them. The Ion 750 even has a smaller dustbin and it’s easier to remove.
