Maybe the wireless ones, like the canary camera, which doesn't look like a camera at first. Maids won't be able to recognize it for sure, unless you tell them. I read they record high quality of videos, but https://smartrobotichome.com/smart-security-camera-comparison/#canary with a high price too.

Roomba user here. It's good with pet hair and other kind of floors, wooden, carpet or tiled. Just a little tweak needed for the battery. Though I read about https://smartrobotichome.com/best-roomba-model-comparison-chart/ and learned that the most high recent models of this vacuum has a better battery life. I might actually get a new one as we have one spacious place that will take so much cleaning time.

Same here. I think it's not healthy to impose to kids that they should be like this and that. I can see that my kid is learning even if it's not that fast like the rest of the classmates, but she's learning and most of all, enjoying. And I think that's the most important thing.

I asked the teacher if we can \"borrow\" their snack time as we planned to bring some pizza, ice cream and cake. Kids enjoyed and was super fun!
