Visvac — Vacuum Cleaner Specs Explained | visvac.com
An ordered procedure that keeps performance, legality, comfort and fit in the right sequence.
Step 1: list suction in pascals, airflow in CFM and output in airwatts for both models, in the same units. If one sheet uses inches of water and the other uses pascals, write both figures down in their own units and note the mismatch instead of guessing a conversion.
Step 2: check the input wattage of each model against the EU 900 W rule that applies from 2017. A figure above 900 W means the sheet predates the rule or the machine is sold outside the European Union; models above 1600 W were banned even earlier.
On narrow screens, swipe or scroll the plate sideways.
Step 3: compare weight in kilograms or pounds and noise in decibels (dB). These two rows do not appear in the performance figures, but they decide whether the machine is usable for the size of the room you clean.
Step 4: match the configuration to the home. Upright, canister, drum, wet/dry, pneumatic and backpack models each suit a different setting; a wet and dry unit that handles both wet and dry soilage may be more machine than a flat needs.
A typical failure mode is comparing watts alone. Because watts measure input power and the EU caps that input at 900 W for every model, two compliant machines can draw the same watts and still differ in suction, airflow and airwatts. A second failure is comparing figures across different units without noting the mismatch; a third is ignoring the configuration row and judging a backpack model by a canister sheet.
