I'm running a bunch of Rokus. Two Roku 3s, one Roku 1, and I just got a Roku 2 to replace the 1 today (on an older TV; I needed the ethernet port). What's bad about Netflix on all of them at once is that you're all putting data into the Netflix recommendations metadata, which will then bombard you with suggestions of the "because you liked" nature. Profiles help this, but don't solve it. Check out this
video. Unfortunately Netflix won't let you disable this feature just yet, but you can manage it by deleting profiles and starting new ones (since you would have to manually delete every title you viewed on your PC otherwise). Also, they are apparently beta-testing what's called "Privacy Mode", which would solve this problem, but only a very few users have access to this right now.
To the OP I would recommend buying something called the Netflix Instant Watch Browser (I'd recommend this anyway as it drastically opens up the number of movies you can browse through on Netflix without direct searching; it basically pulls the catalog from Netflix with the only downside being that you can't access the movies directly yet, you have to queue them up). It's only a few bucks and you can get this
lite version free. This plus Netflix Queue will serve as a decent workaround for people like me, who don't want suggestions or my history tracked.
Or better yet, and if possible, give the Roku 2 to your kids and just use the Smart TV/separate profile for yourself. Or vice versa. Actually, now that I think about it, this is exactly what you need to do. Abandon your main profile to the kids and make your own separate on the Smart TV. Should work perfectly.
EDIT: Just realized OP has already bought a Roku 3. Oh well, this should be good for future reference anyway.
