Here are some tips for streak free floor cleaning:

• Use the right tools. A microfiber mop is a great choice for most floor types, as it won't leave behind any streaks. You can also use a dry mop to buff your floors after mopping to remove any remaining moisture.
• Use the right cleaner. For most floors, a mild cleaner made specifically for floors is the best option. Avoid using harsh chemicals or abrasive cleaners, as these can damage your floors.
• Don't over-wet the mop. A damp mop is all you need to clean your floors. If the mop is too wet, it will leave behind streaks.
• Wring out the mop thoroughly. After dipping the mop in the cleaning solution, wring it out until it is just damp. A wet mop will leave behind streaks, while a dry mop will not clean your floors effectively.
• Mop in the right direction. For most floors, you should mop in a straight line from one end of the room to the other. This will help to prevent streaks.
• Dry the floors completely. After mopping, dry the floors with a dry mop or a towel or set up a floor fan in the area you're working on. This will help to prevent streaks and water spots.

Here are some additional tips for specific floor types:

• Hardwood floors: Use a mild floor cleaner made specifically for hardwood floors. Do not use harsh chemicals or abrasive cleaners, as these can damage your floors.
• Laminate floors: Use a mild floor cleaner made specifically for laminate floors. Do not use polish or wax, as these can build up on the floor and make it difficult to clean.
• Tile floors: Use a mild floor cleaner made specifically for tile floors. You can also use a vinegar solution (1 part vinegar to 3 parts water).

With these tips, you can easily clean your floors without leaving any streaks. Just remember to use the right tools, the right cleaner, and the right technique, and your floors will always look their best.
