Logged in Amazon and it showed a price drop, though it has been at this price previously with some interest. The Neato is arguably the best robot vacuum along with the LG Roboking. Unlike the Roomba (aka ping pong), they plot a cleaning pattern. They do however sometimes suffer from build quality issues, but parts are readily available and there is a massive Whirlpool thread for support. Apparently a laptop charger will solve the US to AU power issue.
The Amazon cart price is US$339.97 including delivery and I used XE to convert to AU$

That is a great deal. One of the best available robots for a bargain price. Thanks
