The fan housing forms a second opening. A fan assembly is positioned at the fan housing. The inlet exhaust housing includes an inlet portion and an exhaust portion. The inlet exhaust housing is rotatable to a first position forming a blower operation and a second position forming a vacuum operation. The debris housing is coupled to the exhaust portion of the inlet exhaust housing. ## Claims ### Claim at position 1 -20. (canceled) ### Claim 21 A blower vacuum, the blower vacuum comprising: a nozzle forming a first opening; a fan housing in fluid communication with the nozzle, the fan housing forming a second opening, wherein a fan assembly is positioned at the fan housing; a debris housing forming a plenum in fluid communication with the second opening at the fan housing; and a separator positioned fluidly between the fan assembly and the plenum at the debris housing, wherein the separator comprises a plurality of vanes extending along a radial direction, the plurality of vanes extending from an inlet centerbody toward an outside wall surrounding the inlet centerbody. ### Claim 22 (depends on 21) The blower vacuum of claim 21, wherein the separator comprises an exhaust centerbody positioned downstream of the inlet centerbody relative to a flow of air from the fan assembly. ### Claim 23 (depends on 22) The blower vacuum of claim 22, wherein an outer flowpath is formed between the exhaust centerbody and the outside wall, and wherein the outer flowpath extends in fluid communication to the plenum at the debris housing. ### Claim 24 (depends on 23) The blower vacuum of claim 23, wherein the exhaust centerbody forms an inner flowpath in fluid communication with an exhaust opening. ### Claim 25 (depends on 23) The blower vacuum of claim 23, wherein the outer flowpath is positioned radially around the exhaust centerbody. ### Claim 26 (depends on 25) The blower vacuum of claim 25, wherein the inner flowpath is positioned radially inward of the outer flowpath. ### Claim 27 (depends on 26) The blower vacuum of claim 26, wherein the exhaust centerbody separates the outer flowpath and the inner flowpath. ### Claim 28 (depends on 21) The blower vacuum of claim 21, wherein the plurality of vanes is configured to induce swirl at a flow of air from the fan assembly. ### Claim 29 (depends on 21) The blower vacuum of claim 21, wherein the plurality of vanes is integral to the outside wall. ### Claim 30 (depends on 21) The blower vacuum of claim 21, the debris housing comprising a removable wall, wherein the wall is a cap selectively sealing debris in the plenum at the debris housing. ### Claim 31 (depends on 21) The blower vacuum of claim 21, wherein the separator is positioned in the debris housing, the separator comprising an exhaust centerbody positioned downstream of the inlet centerbody relative to a flow of air from the fan assembly. wherein an outer flowpath is formed between the exhaust centerbody and the outside wall, and wherein the outer flowpath extends in fluid communication to the plenum at the debris housing, and wherein the exhaust centerbody forms an inner flowpath in fluid communication with an exhaust opening at the debris housing. ### Claim 32 (depends on 21) The blower vacuum of claim 21, comprising: an inlet exhaust housing coupled to the fan housing, the inlet exhaust housing comprising an inlet portion and an exhaust portion, wherein the inlet exhaust housing is moveable to a first position forming a blower operation and a second position forming a vacuum operation. ### Claim 33 (depends on 32) The blower vacuum of claim 32, wherein the separator comprises an exhaust centerbody positioned downstream of the inlet centerbody relative to a flow of air from the fan assembly, wherein the exhaust centerbody forms an inner flowpath in fluid communication with an exhaust opening, and wherein the inlet exhaust housing in the second position positions the second opening and an exhaust opening at the inlet portion in axial alignment to one another. ### Claim 34 (depends on 33) The blower vacuum of claim 33, wherein the inlet exhaust housing in the first position positions the second opening and the first opening in axial alignment to one another. ### Claim 35 A blower vacuum, the blower vacuum comprising: a nozzle forming a first opening; a fan housing in fluid communication with the nozzle, the fan housing forming a second opening, wherein a fan assembly is positioned at the fan housing; an inlet exhaust housing coupled to the fan housing, the inlet exhaust housing comprising an inlet portion and an exhaust portion, wherein the inlet exhaust housing is moveable to a first position forming a blower operation and a second position forming a vacuum operation; a debris housing forming a plenum in fluid communication with the second opening at the fan housing; and a separator positioned fluidly between the fan assembly and the plenum at the debris housing, wherein the separator comprises a plurality of vanes extending along a radial direction, the plurality of vanes extending from an inlet centerbody toward an outside wall surrounding the inlet centerbody. ### Claim 36 (depends on 35) The blower vacuum of claim 35, wherein the separator is positioned in the debris housing, the debris housing comprising the outside wall surrounding the inlet centerbody. ### Claim 37 (depends on 35) The blower vacuum of claim 35, wherein the separator comprises an exhaust centerbody positioned downstream of the inlet centerbody relative to a flow of air from the fan assembly, wherein an outer flowpath is formed between the exhaust centerbody and the outside wall, wherein the outer flowpath extends in fluid communication to the plenum at the debris housing, and wherein the exhaust centerbody forms an inner flowpath in fluid communication with an exhaust opening. ### Claim 38 (depends on 37) The blower vacuum of claim 37, wherein the outer flowpath is positioned radially around the exhaust centerbody, and wherein the inner flowpath is positioned radially inward of the outer flowpath, and wherein the exhaust centerbody separates the outer flowpath and the inner flowpath. ### Claim 39 (depends on 35) The blower vacuum of claim 35, wherein the plurality of vanes is configured to induce swirl at a flow of air from the fan assembly. ### Claim 40 (depends on 35) The blower vacuum of claim 35, wherein the plurality of vanes is integral to the outside wall.
