Frequently asked questions

How long do the Roomba i8 and s9 run?

The Roomba i8 and s9 each have a runtime of 75 to 120 minutes. This means that they can run for up to two hours before needing to be recharged.

Is the Roomba i8 the same as the I7?

The Roomba i8 and the Roomba I7 are two different models of Roomba. The Roomba i8 is the more expensive model, with a price tag of $899.99 on Amazon. It has a higher suction power than the I7 and comes with a self-charging dock and a virtual wall barrier.

The Roomba I7 is the less expensive model, with a price tag of $449.99 on Amazon. It doesn’t have the self-charging dock or the virtual wall barrier, but it does come with remote control.

Will Roomba i8 fall downstairs?

This question has been debated for a while now. Some people say that it definitely will, as the cliff detection feature is not perfect and it could easily fall down a set of stairs. Others say that it is unlikely, as the sensors are designed to avoid obstacles.

Personally, I think that it is possible for the Roomba i8 to fall downstairs. The cliff detect feature may be able to stop it from falling off a ledge, but there is no guarantee that it will work perfectly every time. Additionally, the sensors may not be able to detect every possible obstacle on the stairs, which could result in a fall.
