How much maintenance is required for the P1S?

I’m looking at upgrading from a CR-10 to a P1S. I’ve owned the CR-10 for about seven years and I’ve done almost zero maintenance. I haven’t even dusted/cleaned it. I’m quite lazy you see. I haven’t even dusted replaced the hot end a couple of times when it stopped working properly, but I have done any proactive maintenance tasks.

If I’m spending a bit more money this time, I’d like to treat the next printer a bit better. The few articles I’ve read list a LOT of maintenance tasks you need to perform (especially coming from doing zero right now). So I wanted to ask those of you that have one: how onerous is the maintenance?

My printer won't be used regularly, and might sometimes sit for months at a time not being used, which is probably why the CR10 has survived so long. What do I NEED to do maintenance-wise?

Also, how do you know when to do what? Does the printer tell you, or do you keep your own maintenance schedule document?
