You can change it to 720p to have a clearer picture.
I made this video to demonstrate in depth cleaning of the brush roll, bushings and motor shaft on the Shark cordless Vacuum. As these get bound with hair the battery life becomes shorter.
While I do show you how, you do not actually need to crack the case and clean the motor shaft every time, just go through the brush roll removal and cleaning to improve battery life. Just check the motor shaft every now and then, how often will depend on the hair in your house and the amount you use the vacuum.
I hope you can find some useful information here!
