Frequently Asked Questions [FAQs]

Q1. Do you need Alexa to run iRobot Roomba 891 robot vacuum?

A1. It is never mandatory for you to use Alexa if you wish to use the product as a robovac. Infact, it is just an additional feature for the 891. Very few devices come with the voice command option and the 891 is special in this. You can also use Google Assistant or other wifi connections for use.

Q2. How many square feet will it clean in one run time?

A2. The Roomba does not have any limitations to the floor area unless there is no obstruction. Even if you have a big room or a small floor area, it should work fine. However, the runtime is around 90 minutes when this device has a full charge. So you can expect the product to work well.

Q3. Will the Roomba get tangled up?

A3. The basic mechanism of the Roomba is to work freely when there is no obstruction. However, it starts to detect the obstruction when there is a rise of 1-inch above the floor. Usually, the height of the fringe is not so much. If there is any power cord above 1-inch, it may get tangled.

Q4. Can you program the Roomba 890 manually?

A4. Unfortunately, the iRobots do come with pre-programmed work. So, you may not be able to program them manually. They must all be programmed with the help of a WiFi or an application developed. So you will have to use both these devices accordingly.

Q5. Does it scratch easy?

A5. Both these devices come with rubber pads on the sides as well as the bottom. Moreover, the casters at the base are made up of premium quality. So, they can resist any floor types. Do not worry because the Roomba will not scratch your floor.

Final Verdict

It’s hard to pick one when you compare the two best products. Both 890 and 891 run on the same platform and there’s hardly much difference in the working mechanism. However, because of slight adjustments, iRobot 891 becomes my favorite choice.

You can still go for the iRobot 890 because of the two added features like the dual-mode and the virtual wall accessory. Apart from this, both these devices are quite similar to each other. We hope our comparison of Roomba 890 VS 891 helped you make the perfect choice for yourself.
