Some of its major advantages are:
Using a bar of soap was very unhygienic as everybody who used it touched it with germs. Manual soap dispensers though an improvement still do not have the convenience of an automatic dispenser it is completely sensor operated and touch free.
Perhaps the most obvious and important benefit is with such dispensers there tend to less germs than in other variety of dispensers. Since no human contact is needed for cleaning this is quite a positive especially in toilets and kitchens areas which are quite infected with germs. This is the main reason why currently, having a sensor-activated dispenser is coming to be the cleaner trend.
Automatic Dispensers have a heavier capacity and are quite low maintenance. It would not require refills as often as bar of soaps or other variety of dispensers. Both in homes and in offices or restaurants easy maintenance is quite a big positive.
Easier to use
Automatic dispensers are easier to use as it just involves simply moving the hand close to the dispenser and wait for a few seconds for the soap to drop on your hands automatically. This is sensor activated and is quite hassle free like other dispensers. The whole process is quite effective and simple. Also the process of cleaning a manual dispenser is quite tedious as it has been touched by many and is quite filled with germs.
This type of soap also saves you money by giving out consistent, exact amounts each time. That reduces the consumption of soap considerably and prevents wastage of soap.
Automatic dispenser is kid friendly as it is very easy to use and germ free. It can be used in schools to promote cleanliness and prevent diseases.
