Synthesis is a bagless vacuum cleaner featuring Airvolution, a multi cyclonic technology which keeps the suction power constant, even when the container is almost full. The silver-ion-coated container can collect up to ten litres of dust, which are finally compressed into a volume of only one litre by the integrated Power Active Compaction Technology (PACT), developed by the manufacturer. Synthesis has been developed to ensure extraordinary dust capacity and maximum hygiene.
