L'invention porte également sur un dispositif de nettoyage électrique comportant le dispositif de séparation à cyclone installé à l'intérieur de celui-ci. Une chambre de tourbillonnement d'un premier ordre (12) fait tourbillonner de l'air contenant de la poussière, lequel s'écoule à l'intérieur de celle-ci à partir d'une entrée de premier ordre (11), afin de séparer la poussière de l'air contenant de la poussière, et décharge l'air, à partir duquel la poussière a été retirée, à partir d'une sortie de premier ordre (15). Au moins une partie du bord d'ouverture d'une ouverture d'ordre zéro (113), formée par l'ouverture d'une partie de la paroi latérale de la chambre de tourbillonnement de premier ordre (12), ladite partie du bord d'ouverture étant disposée en aval dans la direction de tourbillonnement de l'air contenant de la poussière, a une forme arrondie. En résultat, la poussière séparée de l'air contenant de la poussière est collectée de façon fiable dans une chambre de collecte de poussière d'ordre zéro (114) sans être prise par le bord d'ouverture de la section d'ouverture d'ordre zéro (113).
