Paint roller with tank - recommended?

Hello everyone, we have finished the shell construction. Currently, the walls are being filled. After that, painting is next, which we would like to do ourselves. Can you recommend paint rollers with an integrated tank? I look forward to your feedback. Best regards & hopefully a happy [Osterfest]

Either use the Airless spray system or roll in the classic way. There is a reason why the rollers with tanks have not become popular. Cleaning, etc., is significantly more complicated.

Tüdelkram. The advantage is not significant, the disadvantage is the weight, cleaning, price.

So far, I don't know of any paint roller with a tank. The idea seems - understandably - misguided to me. "Painter" is a profession, but painting with a roller is not that difficult .... (unless you have a tank in the roller ;))
