The shots can be angled up or down and reflect off of walls, floors, and shields. This attack also passes through opponents, allowing the player to hit multiple foes. R.O.B. must wait one second for the laser to recharge, or R.O.B. will shoot a weak, short-range laser. When the laser is charged, the red light on R.O.B.'s head will begin to flash. Kirby also has this property when he copies R.O.B. There are actually two levels of charge; if the beam is left alone for 20 seconds, it will become the Super Robo Beam. Super Robo Beam is much stronger and thicker, and has increased range (enough to travel all the way across any stage), though it is significantly slower than a normal Robo Beam.
If used at a very close range, the beam will do higher, fire type damage, starting at 9%.

While the move is unique to Brawl, the flashing red light on R.O.B.'s head when the Robo Beam is charged is a throwback to when the red light flashed to indicate that R.O.B. was ready for use with the NES.
- When the beam is uncharged, R.O.B.'s arms will be down instead of facing straight forwards.
- A R.O.B. Blaster uses a purple Robo Beam with somewhat different properties.
- Kirby's "Laser" copy ability from the Kirby video game series is similar to Robo Beam in the way that it ricochets if it hits a slope or another slanted surface.
