Title
(EN) FLOOR CLEANING APPARATUS
(FR) APPAREIL DE NETTOYAGE DES SOLS
Abstract
(EN)
The present invention provides an apparatus for cleaning floors. The apparatus is a sweeper with a cylindrical side broom (140) with an overlying hood (538). A contouring side broom assembly (600) is provided for following contours of a surface. The apparatus is a sweeper that utilizes a pre-filter (362) to remove debris that remains in the vacuum airstream after having passed through the hopper. The apparatus is a scrubber with two counter rotating disk brushes (434, 436), a primary squeegee (422), and a second or pre-squeegee (442) for relieving the primary squeegee from processing the heavier concentration of waste water produced in the area between the brushes.

L'invention concerne un appareil pour le nettoyage des sols. Cet appareil est une balayeuse dotée d'un balai latéral cylindrique (140) recouvert d'un capot (538). Un ensemble balai latéral (600) est conçu pour suivre les contours d'une surface. Cet appareil est une balayeuse dans laquelle un pré-filtre (362) est utilisé pour enlever les débris restant dans le flux de vide après leur passage dans la trémie. L'appareil est une brosseuse dotée de deux brosses discoïdales contre-rotatives (434, 436), une raclette en caoutchouc (422) primaire et une seconde pré-raclette (442) permettant d'éviter à la raclette primaire de traiter la concentration plus grande d'eau usée produite dans la zone des brosses.
