1) Vacuum the floor at least once a week. Make sure you go under everything. If you have carpet it can be a huge trap for dust and keeps your room dusty.
2) dust the furniture in the room at least once a week
3) vacuum out (or use compressed air if you have some) the vents on the PS360 once every few months
4) Get an air purifier/ionizer (this can be expensive and probably not worth it unless you have dust allergies)
1 & 2 are a must if you want to reduce dust and increase the life of your electronic products.
As a note, I hadn't vacuumed the floor in my apartment for a few weeks and just got a Roomba (robotic vacuum) and I ran it last night. The entire dirt compartment was filled to the brim with dust that it pulled out of the rug. I was amazed at how much there was especially since it hadn't been that long since I vacuumed. The big thing was I could actually see it rather than it getting sucked inside a bag in the vacuum.
