How this works
How long should my cordless vacuum run?
Plan for one full-home clean per battery. A 1000 sqft apartment takes about 25-30 min on normal mode; a 2000 sqft home 50-60 min. Add 40% if you have shedding pets, and 70% if you mostly run on boost mode.
Why does runtime drop so much on max suction?
Boost / max mode draws 2-3× the current of normal mode. A spec sheet that says "60 min runtime" usually means ~25 min on max. Always check both numbers if your floors need heavy suction.
Should I get a swappable battery model?
For homes 1500+ sqft, yes — finishing without rushing is much nicer with a second battery. Most premium cordless vacuums offer it. Some bundles ship with two batteries for a small upcharge.
What about charge time?
Most premium cordless vacuums charge fully in 3-4 hours. Cheap models can take 5+ hours. Worth checking the spec — slow charge time makes daily use impractical if you don't finish a clean on one battery.
