Motor efficiency / runtime-per-watt (cordless)

Motor efficiency / runtime-per-watt (cordless)

Best

#1
In battery-efficiency style scoring (airflow on max paired with runtime), the Gen5 Detect is repeatedly credited for converting battery capacity into unusually strong usable airflow per minute, helping explain why it wins battery-life and performance awards despite its high power output.
#2
Reviewers note that the automatic power adjustments can help stretch battery life by using only the power needed. At least one outlet explicitly calls battery efficiency above average.
#3
Low-power output is unusually strong for a cordless vacuum, suggesting good runtime-per-power efficiency compared with many competitors’ low modes.
