A C560XL was conducting a visual approach to Runway 2L. A Falcon 7X aircraft was also conducting a visual approach to Runway 2L in front of the C560XL. The data block for the C560XL indicated 'VS'; which meant that the aircraft had the Falcon it was following in sight and was maintaining visual separation. When the C560XL called the Tower on 120.9; I verified that the pilot had the Falcon in sight; which the pilot confirmed; then cleared him to land on Runway 2L #2. Upon crossing the numbers for Runway 2L; the pilot of the C560XL said that they were going around. I instructed the aircraft to enter left traffic for 2L and cleared him to land. The aircraft landed on 2L safely. After landing; when I asked the pilot the reason for the go-around; the pilot stated that it was wake turbulence behind the Falcon. It is my understanding that when an IFR aircraft accepts a visual approach and visual separation from another IFR aircraft; and that aircraft requires a wake turbulence advisory; that the advisory is given by the Approach Controller; according to FAA Order 7110.65; 2-1-20 a2. Therefore I felt it was redundant to issue the wake turbulence advisory to the C560XL again.In the future I will give wake turbulence advisories to aircraft that require them; regardless of whether or not the advisory may have been given by a previous controller. I should not have assumed that the advisory had already been given; and it would not have caused any harm other than frequency congestion to reissue the advisory to the Citation.
DPA Local Controller stated a C560XL reported encountering wake turbulence on approach in trail of a Falcon 7X.
