The Revenue Minister, Tialavea Tionisio Hunt told the Samoa Observer newspaper the government has made the request to the Chinese government.
Tialavea said the request came as part of efforts to combat drugs being smuggled into the country from the neighbouring territory.
He said border authorities currently had the use of two sniffer dogs based at Faleolo International Airport.
The minister said dogs were like humans and needed to rest, which is why the government was looking at using the robotic "sniffers".
