Which vacuum is more powerful?

Which vacuum is more powerful depends on type and measurement, but generally corded upright and canister vacuums are more powerful than cordless stick or robot vacuums because they have larger motors plugged into wall outlet providing continuous power. Among household vacuums, powerful models include Dyson Ball Animal 3 with 290 air watts, Miele Complete C3 with 1200 watts motor, and Shark Stratos with strong suction and DuoClean. Cordless stick vacuums like Dyson Gen5detect claims 280 air watts which is powerful for cordless but still less than some corded. Shop-Vac wet dry vacuums are very powerful for debris with high airflow. Industrial central vacuum systems are most powerful for home with motor in garage. Power can be measured by suction in air watts, pascals, or water lift, and airflow in CFM. For robot vacuums, Roborock S8 Pro Ultra with 6000 Pa is powerful among robots but less than uprights. So if you ask which is more powerful between two specific vacuums, compare air watts and sealed suction, corded usually wins, but for convenience cordless and robot may be powerful enough for daily cleaning, while deep carpet cleaning needs upright or canister.
