Nintendo Chiritorie (無線クリーナー チリトリー) 

A remote-controlled vacuum cleaner made by Nintendo, released in 1979. From the blog Before Mario:

Chiritorie is a remote controlled, battery operated mini vacuum cleaner. It measures a mere 16 centimeters across, with a small fan providing dust-sucking action. Although it can actually vacuum, this is not intended for serious cleaning. It would take you all day to do a single room. 

Chiritorie was released in 1979, and retailed for ¥5,800. It did not become a big seller and was produced in relatively small numbers, making it one of the rarer Nintendo toys and very difficult to find these days.

Embedded below is a video of the machine in action:
