It might be unpopular on HN, but use the older iRobot generation that is not "smart" aka no WiFi, no spyware, just a "dump" little robot vacuum cleaner. Do you think Mark Zuckerberg, or Elon Musk let such devices roam their home? Nope. Mark wrote his own home assistant, security system ,etc with PHP and unix tools. These devices are for the noobs, the general public, that doesn't care.
