Some common Shark vacuum problems include loss of suction and whistling noises from the filter. Other problems include broken or worn out belts.
The exact type of common problem depends on the model of Shark vacuums. For vacuums with a filter in place, it is not unusual for the filter to become dirty or clogged with dust and debris. On some models, including the Shark Rocket, the vacuums can stop standing upright without assistance. In some models with rotator brushes, the vacuum can become hard to push, especially when used on a low-height setting. Another typical problem is clogging of the machine or hoses due to pet hair.
