Exemplary landscape maintenance systems include an air flow generation mechanism such as a vacuum and/or blower, a wand assembly having a forearm cuff assembly and a joystick handle assembly, and a nozzle assembly having an agitator assembly. The agitator assembly may include one or more spines or leaflets. The air flow generation mechanism may include a port in fluid communication with the wand assembly. The air flow generation mechanism may also include a port in fluid communication with an exhaust conduit, the exhaust conduit may be attached with a receptacle bag, and the receptacle bag may have a bag frame disposed therein. ## Claims ### Claim 1 A landscape maintenance system, comprising: an air flow generation mechanism; a nozzle assembly; and a wand assembly coupled with the air flow generation mechanism and the nozzle assembly, wherein the nozzle assembly includes a flange, a flange cover, and an agitator assembly. ### Claim 2 (depends on 1) The landscape maintenance system of claim 1, wherein the agitator assembly comprises an agitator having an elongate spine and a proximal head. ### Claim 3 (depends on 2) The landscape maintenance system of claim 2, wherein the flange comprises an agitator aperture, wherein the agitator aperture is configured to receive the elongate spine of the agitator, and wherein the proximal head of the agitator is sized so that it cannot pass through the agitator aperture of the flange. ### Claim 4 (depends on 1) The landscape maintenance system of claim 1, wherein the nozzle assembly further includes a lid fastener configured to secure the flange cover to the flange. ### Claim 5 (depends on 1) The landscape maintenance system of claim 1, wherein the flange cover comprises a first part and a second part. ### Claim 6 (depends on 5) The landscape maintenance system of claim 5, wherein the first part of the flange cover has a semi-circular shape. ### Claim 7 (depends on 1) The landscape maintenance system of claim 1, wherein the flange cover is removable from the flange. ### Claim 8 (depends on 1) The landscape maintenance system of claim 1, wherein the agitator is removable from the flange when the flange cover is removed from the flange, and wherein the agitator is locked in position relative to the flange when the flange cover is secured with the flange. ### Claim 9 (depends on 1) The landscape maintenance system of claim 1, wherein the agitator assembly comprises an agitator having an elongate spine and a proximal head, and wherein the flange cover covers the proximal head of the agitator when the flange cover is coupled with the flange. ### Claim 10 (depends on 1) The landscape maintenance system of claim 1, wherein the agitator assembly comprises an agitator having an elongate spine and a proximal head, and wherein the agitator does not extend into the flange cover when the flange cover is coupled with the flange. ### Claim 11 (depends on 1) The landscape maintenance system of claim 1, wherein the agitator assembly comprises an agitator having n elongate spine and a proximal head, wherein the flange comprises an agitator aperture, wherein the agitator aperture is configured to receive the elongate spine of the agitator, wherein the proximal head of the agitator is sized so that it cannot pass through the agitator aperture of the flange, and wherein the nozzle assembly further includes a lid fastener configured to secure the flange cover to the flange. ### Claim 12 (depends on 1) The landscape maintenance system of claim 1, wherein the agitator assembly comprises an agitator having an elongate spine and a proximal head, wherein the flange cover covers the proximal head of the agitator when the flange cover is coupled with the flange, and wherein the agitator does not extend into the flange cover when the flange cover is coupled with the flange. ### Claim 13 (depends on 1) The landscape maintenance system of claim 1, wherein the nozzle assembly further includes one or more lid fasteners configured to secure the flange cover to the flange. ### Claim 14 (depends on 1) The landscape maintenance system of claim 1, wherein the nozzle assembly comprises a distal port having a central longitudinal axis, wherein the agitator assembly comprises an agitator having a proximal head that is located a first distance from the central longitudinal axis and an elongate spine having a distal end that is located a second distance from the central longitudinal axis, and wherein the second distance is greater than the first distance. ### Claim 15 (depends on 1) The landscape maintenance system of claim 1, wherein the nozzle assembly comprises a distal port having a central longitudinal axis, wherein the agitator assembly comprises a plurality of agitators each having a proximal end and a distal end, and wherein the plurality of agitators extend distally from the flange in a radially divergent pattern about the central longitudinal axis of the distal port of the nozzle assembly so that the distal end of each agitator is further away from the central longitudinal axis of the distal port of the nozzle assembly than the corresponding proximal end of each agitator. ### Claim 16 (depends on 1) The landscape maintenance system of claim 1, wherein the nozzle assembly further includes an adjustable airflow regulator mechanism. ### Claim 17 (depends on 16) The landscape maintenance system of claim 16, wherein the adjustable airflow regulator mechanism comprises one or more apertures. ### Claim 18 (depends on 16) The landscape maintenance system of claim 16, wherein the adjustable airflow regulator mechanism comprises a regulator sleeve. ### Claim 19 (depends on 16) The landscape maintenance system of claim 16, wherein the adjustable airflow regulator mechanism is operable to transition between an open mode and a closed mode. ### Claim 20 (depends on 1) The landscape maintenance system of claim 1, wherein the nozzle assembly comprises a proximal end having a first shape configured to couple with the wand assembly and a distal port having a second shape, and wherein the second shape is different from the first shape. ### Claim 21 (depends on 1) The landscape maintenance system of claim 1, wherein the nozzle assembly comprises a proximal end having a first cross sectional area configured to couple with the wand assembly and a distal port having a second cross sectional area, and wherein the second cross sectional area is different from the first cross sectional area.
