From the standard model 600 series of the robot vacuum cleaner "Roomba", the Japanese original model "Roomba 641" was released today (November 22nd). The price at the iRobot official online store is 39,880 yen (excluding tax).
Roomba's unique three-stage cleaning system thoroughly scrapes out dust, dust, and large debris and sucks them in, as well as convenient functions such as an automatic charging function. In addition, dozens of sensors of the high-speed response process "iAdapt" accurately grasp the situation of the room, and it seems that it will intensively clean the place with a lot of dust until it is judged that it is clean.

The size is maximum width 340 x height 92 mm, and the color is blue silver only. Since it does not support Wi-Fi, it cannot be operated from the smartphone app, but it comes with a "dual virtual wall" that allows you to set places where you do not want Roomba to approach.
"Invisible wall" can also be installed
