soap and detergent are the fatty salts of sodium or calcium. it has two ends one that is hydrophobic (water repellant) and hydrophillic(water loving). the hydrophobic part get attached to dirt and hydophilic part will pull hydrophobic part. hence forming a micelle which will get out in form of bubble

SOAP
It works because soap is made up of molecules with two very different ends. One end of soap molecules love water - they are hydrophilic. The other end of soap molecules hate water - they are hydrophobic. Hydrophobic ends of soap molecule all attach to the oil.
DETERGENT
Water alone can't clean clothes because it won't attach to molecules of grease and dirt. Detergent is different. The surfactants it contains are made of molecules that have two different ends. One end is strongly attracted to water; the other is attracted to oily substances like grease.
