Jacuzzi sex?

My boyfriend has a jacuzzi and I was wondering if it’s safe to have sex in it. There’s a pool cleaner that comes around every 2 weeks or so however what I’m more concerned about is if there’s a risk of getting pregnant if we do it inside the water? We have never done this and always make sure to wear condoms but with this I don’t think it’s possible to wear condoms?! Or can he still wear it?
