Vacuum cleaner assembly

Abstract

A vacuum cleaner assembly is provided that includes a body extending along an axis to a base connection end that includes a protrusion. A handle extends from the body opposite the base connection end. A dust collection portion includes a body connection end that includes a track with a lock passage extending perpendicularly from the track. The protrusion is located in the lock passage in a locked position and in the track in an unlocked position to selectively remove the dust collection portion from the body.

         4 . The vacuum cleaner assembly of  claim 3 , wherein the base connection end includes three diametrically opposed protrusions and the body connection end includes three equally spaced tracks and lock passages. 
     
     
         5 . The vacuum cleaner assembly of  claim 1 , wherein the handle extends from the body at an angle transverse to the axis. 
     
     
         6 . The vacuum cleaner assembly of  claim 5 , wherein the dust collection portion includes a base connected to the body and a nozzle extending from the base opposite the body. 
     
     
         7 . The vacuum cleaner assembly of  claim 6 , wherein the base defines the body connection end. 
     
     
         8 . The vacuum cleaner assembly of  claim 7 , wherein the nozzle includes a top edge and a bottom edge extending between a pair of side edges, the top edge extends further away from the body than the bottom edge such that the side edges define a transverse angle relative to the axis. 
     
     
         9 . The vacuum cleaner assembly of  claim 8 , wherein the angle defined by the handle has a magnitude between the axis and the angle defined by the side edges of the nozzle. 
     
     
         10 . The vacuum cleaner assembly of  claim 6 , wherein the nozzle includes an attachment connection member for connecting at least one attachment. 
     
     
         11 . A vacuum cleaner assembly comprising:
 a body extending along an axis to a base connection end;   a handle extending from the body opposite the base connection end;   a dust collection portion extending between a body connection end for selective attachment to the base connection end and a nozzle;   a motor and an impeller driven by the motor are located in the body for creating suction;   a dust collection cavity defined inside of the dust collection portion and a filter located between the dust collection portion and the impeller; and   the nozzle defining a nozzle face sized for connecting to at least one attachment.   
     
     
         12 . The vacuum cleaner assembly of  claim 11 , wherein the nozzle defines a passage to the dust collection cavity and a door engages the passage to prevent debris from exiting the dust collection cavity. 
     
     
         13 . The vacuum cleaner assembly of  claim 12 , wherein the door is biased in a closed position that closes the passage and an open position facilitated by the suction from the impeller that opens the passage. 
     
     
         14 . The vacuum cleaner assembly of  claim 11 , wherein the at least one attachment includes a first attachment and a second attachment that each include a connection feature for connecting the first attachment to the second attachment in a stacked position such that only one of the first attachment and the second attachment are operably attached to the nozzle at a time. 
     
     
         15 . The vacuum cleaner assembly of  claim 14 , wherein the first attachment includes a scraper attachment that includes a scraper bucket with a bottom edge including a lip that narrows into an apex. 
     
     
         16 . The vacuum cleaner assembly of  claim 15 , wherein the second attachment includes a crevice attachment. 
     
     
         17 . The vacuum cleaner assembly of  claim 16 , wherein the scraper attachment and the crevice attachment each include a nozzle connection mouth for insertion of the nozzle face. 
     
     
         18 . A vacuum cleaner assembly comprising:
 a body extending along an axis to a base connection end;   a handle extending from the body opposite the base connection end;   a dust collection portion extending between a body connection end for selective attachment to the base connection end and a nozzle;   a motor and an impeller driven by the motor are located in the body for creating suction;   a dust collection cavity defined inside of the dust collection portion;   a user interface having a button region; and   a control unit configured to apply different vacuum strengths based on at least one functional sequence of activating the button region.   
     
     
         19 . The vacuum cleaner assembly of  claim 18 , wherein the at least one functional sequence includes a first functional sequence comprising:
 pressing and releasing the button region causing the control unit to facilitate a normal speed of the impeller causing a normal suction strength; and   during the normal speed of the impeller, pressing and holding the button region causing the control unit to facilitate a high speed of the impeller causing a high suction strength greater than the normal suction strength; and   during the high speed of the impeller, releasing the button region causing the control unit to facilitate the normal speed of the impeller.   
     
     
         20 . The vacuum cleaner assembly of  claim 18 , wherein the at least one functional sequence includes a second functional sequence comprising:
 while the impeller is at a zero speed, pressing and holding the button region causing the control unit to facilitate a high speed of the impeller causing a high suction strength; and during the high speed of the impeller, releasing the button region causing the control unit to facilitate a normal speed of the impeller with a normal suction strength that is less than the high suction strength.
