#1 Can you clean the inside of the canister with soap water?
We do not recommend using any liquid to clean out the dust cup. Once it is empty, please use a dry cloth to wipe it out.
#2 Is the power head (brushroll) power-driven by the motor or air-driven by the suction of the vacuum?
We would like to inform you that the floor nozzle for the Shark® APEX® UpLight™ Lift-Away® DuoClean® with Self-Cleaning Brushroll Stick Vacuum has an electric motor to spin the brushrolls.
#3 Can the Shark Uplight stand upright on it's own when you pause in your vacuuming process?
the Shark® APEX® UpLight™ Lift-Away® DuoClean® with Self-Cleaning Brushroll Stick Vacuum will stand on its own when the vacuum is not being used.
