Switching from traditional string mops to microfiber flat mops for mopping involves a bit of a learning curve. For cleaning contractors who are used to the old method, streaking with microfiber flat mops can become a common complaint amongst employees. However, with proper training on the use of microfiber flat mops, this problem can easily be addressed. 

The owner of a cleaning business recommends starting with the correct mop wetness level, followed by using the right amount of pressure for the mop to glide smoothly across the floor. Avoiding over-wetting the mop and ensuring that it is properly wrung out are also essential to achieving a streak-free surface. 

With a few adjustments to technique, the switch to microfiber flat mops can result in a more efficient and effective cleaning process.
