NV350 Shark Upright Vacuum

Hi Jessplas, thank you for reaching out. According to our research, to replace the roller follow these steps: - Lift the latches on both sides of the vacuum to release the dust canister. - Remove the dust canister from the vacuum by lifting it up. - Lay down the vacuum to access the bottom panel of the roller compartment. - Using the metal spludger, pry the two small wheels located at the two bottom corners of the vacuum to remove them. - Remove the eight 19mm Phillips #2 screws from the plastic cover. - Remove the two 14 mm Phillips #2 screws from the upper section of the plastic cover. - Remove the wheels by pulling them out of their axles, away from the vacuum. - Gently pull the grey lower part of the roller compartment away from the purple upper part of the compartment. - Lift up and then pull the roller belt off of the roller and the motor to remove it. - Take out the roller by lifting it out of its tray. Install the new roller and reassemble all the parts. We hope this helps!
