A dust-capturing gutter broom assembly comprises gutter broom mounted for rotation about a gutter broom axis. A gutter broom shroud is mounted in surrounding relation to the gutter broom. An air outlet in the gutter broom shroud permits the egress of dust laden air from the gutter broom shroud. A fan is connected in air flow relation with an air outlet of the gutter broom shroud, for causing the ancillary volume of dust-laden air to egress from the gutter broom shroud via the air outlet, to be filtered by a gutter broom filter. A broom-presenting side opening permits said gutter broom to sweep against a lateral surface and a debris-receiving front opening for permitting ingress of debris into the substantially hollow interior of the gutter broom shroud. A movable member is operatively mounted on the gutter broom shroud for selectively altering the size of the debris-receiving front opening.
