The break-in happened at about 5 p.m. on Tuesday. The home is located just east of Wausau on Highway N.
Investigators say two men entered the home of Al and Mary Schreidell who own Rainbow Laundromat. The suspects hit the couple over the head.
Although their injuries aren't life threatening, they were both sent to the emergency room.
This isn't the first time the family has been a victim of crime. Their home was also broken into last summer.
Investigators say they're not sure if the house was targeted because of it's location along Highway N or if the two break-ins are connected.
According to witnesses, the two men responsible for the latest robbery were both black and wearing ski masks. Investigators are still gathering information on the case.
Mary and Al Schreidell were both released from the Wausau hospital and are home recovering.
