Abstract: A vacuum container compromising a vacuum producing means to create a vacuum within said container, a conduit to vacuum solids or liquids into the vacuum container, an access door and a means to close and/or open the access door from within the vacuum container. The door closure/opening means having door attachment means so as to equalize sealing pressures throughout the door sealing means. The door closure/opening means may be powered by a means disposed within the vacuum container or located external to the vacuum container. A means external to the vacuum container may be used to activate the internal door closure/opening means. Should the internal door closure means fail to open the door, an external fastener or access means may be used to override or remove the internal closure means.

Abstract: A method for removing debris from a roof gutter includes the steps of providing a vacuum conduit having a first end located in proximity to the debris in the gutter and a second end connected to a vacuum tank, having a vacuum producing means, the first end of the vacuum conduit having water and/or air dispensing means to dislodge or make vacuum able the debris located within the gutter. The debris is vacuumed into the vacuum tank by means of the vacuum conduit. Mechanical means may also be utilized in proximity of the first end of the vacuum conduit to break up debris. A monitoring means may be utilized in proximity to the first end of the vacuum conduit to monitor vacuuming progress and/or control vacuum and/or debris dislodging means.

Abstract: A container device having both a silencer chamber and an air filter chamber disposed within it and inlet and outlet conduits to each chamber and the two chambers compliment each other by the filter chamber providing acoustic qualities for the silencer chamber and the silencer chamber providing harmonic vibration to the filter chamber for filter cleaning assistance.
