Vacuum Tools & Calculators
Free, practical tools for a cleaner home — measure suction power, estimate runtime and coverage, budget filter and energy costs, and plan your cleaning time.
Suction Power (Air Watts) Calculator
Convert a vacuum's airflow (CFM) and water lift (inches of H2O) into Air Watts — the standard figure manufacturers use to compare real cleaning suction
Vacuum Runtime Calculator
Estimate how long a cordless or robot vacuum runs on a full charge from its battery capacity in watt-hours and its power draw in watts
Room Cleaning Time Calculator
See how many minutes a thorough vacuum should take from a room's floor area and your cleaning rate — handy for planning a cleaning schedule
Filter Replacement Cost Calculator
Project the annual cost of keeping your vacuum or air purifier's filter fresh from the filter price and how many times a year you replace it
Vacuum Energy Cost Calculator
Work out the yearly electricity cost of running your vacuum from its wattage, weekly usage, and your local price per kWh
Robot Vacuum Coverage Calculator
Estimate the floor area a robot vacuum can cover on a single charge from its runtime and its cleaning rate in square feet per minute
