So I got given a robot vacuum by well meaning relatives. Nice sounding name but it's actually a Chinese brand. Turns out the only way it can be made to work is to download the (Chinese co's) app on your phone - it is an 'internet of things' device. That app links back to a server in China. I am a bit worried it is harvesting all my personal details off the phone and selling them to tik tok or KAOS.

What to do?
