ROBOT VACUUM CLEANER MAKING DISTURBANCE DUE TO AIR Russian patent published in 2005 - IPC

FIELD: vacuum cleaning.

SUBSTANCE: robot vacuum cleaner can be used for cleaning surfaces from dirt and dust while automatic moving without using hands of user to give the direction of motion. Robot vacuum cleaner has case provided with sucking-in hole for pulling dirt and dust from surface to be cleaned in, wheel disposed at lower part of case, air circulation mechanism intended for filtering pollution from air which brings the pollution inside sucking-in hole to provide subsequent feeding of air jet being free from dirt and dust to the holes made close to sucking-in holes. Rotating brush is mounted close to suck-in hole which brush is made for wipe dirt and dust to help the pollution to be separated from the surface to be cleaned. To isolate area between surface to be cleaned and case of vacuum cleaner there is a sealing member provided which member protrudes from lower surface of case to make contact with surface to be cleaned. The member is made in form of skirt to embrace holes for jets and suck-in hole to prevent dissipation of pollution out which pollutions are separated by pressure of air jets from holes and brush. Air circulation mechanism has circulation pump disposed inside case of vacuum cleaner, tube for sucking air in which connects circulation pump with suck-in hole, filter disposed inside tube for sucking air in and tube for air jet which tube connects circulation pump with holes for air jets.

EFFECT: improved efficiency.
