Cordless vacuum suction power is typically measured in air wattage (AW), but you’ll see some that list the power of the motor in wattage (W) instead. Typically the higher the air or motor wattage the stronger the suction power, offering improved cleaning performance. And often strength is proportional to price — more expensive cordless vacuums tend to have stronger suction power. A general rule of thumb is that those with precocious pets or mess-making children would benefit from a cordless stick vacuum cleaner with stronger-than-average suction power.
