I disconnected my Roomba from the network right after programming its schedule. It still works great, following the same schedule for 7 years.
I recently bought a cheap Chinese roomba clone. It comes with a remote control so you don't need to connect it to the internet. I do have to press a button to start it but it works great.
If you care about your privacy, choose products appropriately and/or take 5 minutes to protect yourself. Most people don't seem to care, which is their choice.
> Most people don't seem to care, which is their choice.
Most people don't have the required knowledge to make an educated decision about whether to care. In fact, most people are not even aware of the question, let alone have the knowledge, let alone caring, let alone making a choice.
