• First of all, you need to turn off and unplug the vacuum cleaner.
• Now pull the red locking knob, located just above the soleplate, in the opposite direction of the arrow to detach the nozzle from the vacuum cleaner body.
• Place the vacuum cleaner upside down on the floor.
• Now open the battery door and remove the vacuum cleaner battery.
• Pull the plastic handle towards you to remove the dust bin.
• Now insert a pry stick between the transparent bin latch that is located at the center and the brush bar housing. Now, twist the pry stick to disengage the brush roll housing.
• Now gently pull out the brush roll from the housing. Remove the old belt and put the new belt in place.
• Now turn the opposite way to reinstall the brush roll housing and the dustbin. Close the battery door, attach the nozzle to the vacuum cleaner, and you are done!
