Vivinavi

Roomba 900Series

It was purchased 3 years ago and used infrequently, a few months.
It was cleaned and stored.
The suction power is strong and it automatically goes back to where it is charged.
The accumulated dust can be easily disposed of with a single touch.

Equipped with dual virtual walls, it creates an invisible infrared wall in places where you want to restrict Roomba's entry, such as an entrance with no steps.
