This Robot Vacuum Aims to Compete With the Suction Power of a Stick Vacuum

Robot vacuums are a great way to do some general cleaning, but most lack the power of a dedicated vacuum cleaner because you can’t pack enough suction into a small design. iRobot may have an interesting solution for that with its new Roomba Max 875 Combo, which it describes as the “most powerful robot ever” because it uses a proprietary vacuum seal technology that concentrates suction power on the floor.

“With the Roomba Max 875 Combo Robot, we not only increased overall suction power, but also changed how that suction gets applied to the carpet,” Adam Pope, vice president and chief engineer at iRobot, said in a statement. “With SealForce, we’re able to seal the chassis against the carpet fibers, so the airflow, which has the greatest impact on pickup performance, has somewhere to go instead of escaping around the edges. More suction helps, but the seal is what takes...
