Around 10 p.m., two male intruders forced their way into a home in the 1100 block of Bending Willow Way through a second-story window, police Lt. Ron Raman said.
Police said the suspects demanded money from the 35-year-old woman, whose children, ages 6 and 3, slept nearby.
The woman complied with the suspects' demands but at one point pushed a "panic button" on her alarm system. That prompted a struggle with the suspects during which they hit her several times in the face and upper body, Raman said.
The victim called 911 after the suspects fled through the front door.
She was taken to a hospital and treated for bruising to her face and arm.
Police said the suspects kept the hoods of their sweatshirts over their faces during the home invasion to conceal their identities. They did not appear to have any weapons.
According to police, a silver SUV similar to a Chevrolet was seen in the area at the time of the robbery.
Both suspects remain at large, and anyone with information about them is asked to call Pittsburg police (925) 646-2441.
