The Eufy RoboVac 11S Max is only 2.85 inches tall — it slides under almost anything

At just 2.85 inches tall, the Eufy RoboVac 11S Max slides under cribs, couches, and low dressers with at least 3 inches of clearance. That’s unusually slim — most robot vacuums hover around 3.5 to 4 inches. The trade-off is that slim robots usually have smaller dustbins and weaker suction because there’s less room for the motor and bin assembly. But if your home has low-profile furniture where a standard robot would get stuck, the 11S Max is one of the few options that can actually reach those dust bunnies.
