The rotary brushes move up and down in accordance with the height of the floor. When they hit a bump such as of a carpet, doorsill and controller of an electric carpet, they are pulled into the body so that they do not catch on it. The height difference between the bottom of the robot and the floor is about 15mm, and the robot can go over a 20mm-high bump.

The robot comes with the same bristle brushes as canister vacuum cleaners. The rotation speed of the fan motor for collecting dust is 12,500 revolutions per minute, which realizes a strong suction power, Toshiba Lifestyle Products & Services said.

Two of the three models, "VC-RCX1" and "VC-RVD1," come with a charging dock that automatically vacuums dust collected by the robot and stores it in its own dust box every time when the robot is charged on the dock. As a result, the suction power of the robot is not weakened by the dust accumulating in it. The dust box needs to be emptied about once a month.

The VC-RCX1 has a built-in camera and wireless communication capability. When the user sends an instruction to the robot with a smartphone (even when the user is away from home), it moves to a spot preset by the user (where a "photo pointer" has been placed), takes a picture and sends it to the phone so that the user can check the conditions of the room. By purchasing separately-sold photo pointers (manufacturer's suggested retail price: ¥4,700), it becomes possible to take pictures from up to three spots).

The manufacturer's suggested retail prices of the VC-RCX1, VC-RVD1 and "VC-RV1" are about ¥120,000 (approx US$1,155), 90,000 and 75,000, respectively. Toshiba Lifestyle Products & Services aims to sell 6,000 units of the robot per month.
