I'm thinking of buying my grandmother a Robot vaccuum cleaner. I like Miele and saw this and wondered if anyone had any experience of them.
I have a vague memory of reading somewhere that some of these robo cleaners are to be avoided because they are internet connected and upload plans of your home that are easily hackable and a security risk. I have zero clue whether this is true or rubbish so would welcome thoughts on robo cleaners generally and recommendations.
