There are three different types of TechnoClean Microfibre Mopping Systems. The first being the Bucket-Less Aquamop where no bucket is used that could hold contaminated cleaning solution. A new mop cover is used for each new room in Healthcare facilities and the previously used one is placed in a bag for laundering. The second is a system where mops are Pre-Soaked in a bucket with the right amount of moisture to clean the next room with a seperate mop cover. The third is a Smart-Mopping System where a Microfibre Mop is used that folds in half to allow the mop cover to be rinsed in a Smart Bucket. This system is used where there are no cross contamination issues or where the same bucket stays in one area like a kitchen. This is the best system if you need to rinse and wring out the same mop head many times.
