Room smells even though I clean it?

It stinks in my room even though I take care of it.

There's carpet on the floor, and the playstation is running 24/7, which can also be a factor

I would like to know how it doesn't stink anymore

Replace bed linen, ventilate, clean the carpet if possible

Bed linen and varnish washed every 3-5 days the window is always open how should you clean the carpet?

My mother has our carpets cleaned by a cleaning company
