Anthbot Pion 1000
A good cheap mower from Anthbot

Review Summary
Singapore's Anthbot is out to make robot mowers better, and the Pion 1000 is a reasonable effort at this. It's a pretty standard robo mower with wired set-up and a fairly basic app. But it is good value and does what you would expect.
One word of caution: the Pion is an older model, and the company's focus seems to be more on the new Genie range (kickstarting currently).
