About Vacmux
The vacuum aisle doesn’t explain itself
Every vacuum listing throws a different set of numbers at you: watts, Air Watts, inches of water lift, milliamp-hours of battery, square feet of coverage. None of it lines up between brands, and none of it tells you what actually matters — whether an upright will make it through a whole house before the filter needs changing, or whether a robot vacuum’s battery will die halfway across a two-bedroom apartment before it gets back to the dock. Vacmux exists to turn those scattered spec-sheet numbers into answers you can actually use.
Turning spec-sheet numbers into real answers
Each tool here takes the raw figures off a vacuum’s box or manual and converts them into something concrete. The Suction Power (Air Watts) Calculator takes a vacuum’s airflow in CFM and its water lift in inches of H2O and converts them into Air Watts — the figure manufacturers actually use to compare real cleaning suction, which is handy when two listings quote suction in completely different units. The Vacuum Runtime Calculator works out 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, and the Robot Vacuum Coverage Calculator takes that runtime together with a cleaning rate in square feet per minute and estimates how much floor a robot can realistically cover before it needs to dock.
The Room Cleaning Time Calculator estimates how many minutes a thorough pass over a room should take, from its floor area and a cleaning rate — useful for planning a cleaning schedule around a real week instead of guessing. And because a vacuum keeps costing money long after you buy it, the Filter Replacement Cost Calculator projects the yearly cost of keeping a filter fresh from its price and how often you replace it, while the Vacuum Energy Cost Calculator works out the yearly electricity cost of running a vacuum from its wattage, weekly usage, and your local price per kWh.
Alongside the tools, the blog and the learn section cover vacuum types and brand differences, suction and filtration explainers, and floor and carpet care in plain language. If you want a break from spec sheets entirely, The Vacuum Museumis a lighter, browsable gallery of some of the world’s landmarks and wonders, built from Wikipedia and Wikimedia Commons entries — it has nothing to do with vacuums, and it’s there simply because it was fun to build.
What this site is — and isn’t
Vacmux is an independent, advertising-supported site. It isn’t affiliated with, endorsed by, or officially connected to any vacuum manufacturer or brand named in its reviews and comparisons. Every calculator here produces an estimate based on the numbers you type in — actual results depend on your specific machine, your home, and how you use it, so treat the output as a planning figure, not a guarantee. Nothing on this site is professional cleaning, electrical, or appliance-repair advice; for warranty questions, electrical work, or manufacturer-specific maintenance, check your vacuum’s manual or contact the manufacturer directly.
