When cleaned on a regular basis a hardwood floor will last for decades with little additional maintenance.
Purchase a good floor mop. There are special hardwood mops available. These have flat heads and washable/replaceable pads. If you have large open spaces it helps to have a larger mop. A small mop is useful for confined spaces.
A good microfiber mop can be useful for dry sweeping the floor. A microfiber cloth is good for tight corners.
Tea is actually very good for cleaning wooden floors.
Sweep the floor first to remove larger particles, or vacuum with a soft attachment.
Boil 4 to 6 cups of water in a saucepan or kettle, and add 3 to 4 tea bags. Continue boiling for ten minutes.
Remove the tea bags (use some tongs or something similar) and pour the water into the bucket used for mopping.
When the tea has cooled slightly, to the point where you can touch it without burning, start to mop the floor. Wear a pair a rubber gloves to protect your hands.
Mop the floor in the direction of the grain. The mop should be damp but not soaking wet.
Ventilate the room so the floor dries as quickly as possible.
As soon as you are finished remember to soak the mop in cold water to remove the colour of the tea.
Tea can give the floor a good shine. Often the cheapest type of black tea works the best. Else, you can try scented teas for a pleasant smelling room.
