Ninja Vacuum Problems: 7 Common Issues (solutions)

Ninja vacuum common problems related to loss of suction, brush roll not spinning, overheating or shutting off, unusual noises, cord issues or malfunctioning control.

Now we have answered the main question, let’s dive into troubleshooting.

Loss of Suction Power:

One of the most common problems with any vacuum cleaner is a loss of suction power, and Ninja vacuums are no exception.

If you notice a significant decrease in suction, it can impact the overall cleaning performance.

Possible Solution:

  • Check the dust cup or bag for fullness. Empty or replace it as needed.
  • Inspect the filters, including the pre-motor and post-motor filters. Clean or replace them if they are dirty or clogged.
  • Ensure there are no blockages in the hoses, brush roll, or nozzle. Remove any debris or obstructions that may hinder airflow.

Brush Roll Not Spinning:

A non-rotating brush roll can make it difficult to pick up dirt and debris effectively, especially from carpets.

Possible Solution:

  • Check if the brush roll switch or button is turned on. Some models have a dedicated switch to control the brush roll.
  • Inspect the brush roll for any tangled hair, threads, or debris. Use scissors or a brush to clean it thoroughly.
  • Ensure the belt connecting the brush roll to the motor is intact and properly aligned. Replace the belt if it is worn or broken.

Overheating and Shutting Off:

If your Ninja vacuum overheats and shuts off during use, it can be frustrating and disrupt your cleaning routine.

Possible Solution:

  • Allow the vacuum to cool down for at least 30 minutes. Overheating often occurs when the motor or filters are clogged, restricting airflow.
  • Check and clean the filters, removing any accumulated dust and debris. A clean filter promotes better airflow and helps prevent overheating.
  • Ensure that the dust cup or bag is not full, as this can restrict airflow. Empty or replace it as necessary.

Unusual Noises or Vibrations:

Unusual noises or excessive vibrations coming from your Ninja vacuum can indicate underlying mechanical issues.

Possible Solution:

  • Turn off the vacuum and unplug it from the power source.
  • Inspect the brush roll, wheels, and other moving parts for any obstructions, loose screws, or damage. Tighten or replace parts as needed.
  • If the issue persists, contact Ninja customer support or a professional technician for further assistance.

Power Cord Issues:

Power cords can become damaged or tangled, affecting the vacuum’s functionality and posing safety risks.

Possible Solution:

  • Check the power cord for any visible damage, such as cuts or frayed areas. If damaged, replace it immediately to avoid electrical hazards.
  • Untangle any knots or kinks in the cord to ensure proper power supply.
  • Always unplug the vacuum by pulling the plug itself, not the cord, to prevent strain on the internal wiring.

Battery Life and Charging Problems (Cordless Models):

Cordless Ninja vacuums rely on batteries for operation. If you experience issues with battery life or charging, it can hinder their usability.

Possible Solution:

  • Ensure the battery is properly inserted and securely connected to the vacuum.
  • Clean the battery contacts and the charging dock with a dry cloth to remove any dirt or debris that may interfere with charging.
  • Follow the manufacturer’s instructions for charging time and procedures to optimize battery life and performance.

Malfunctioning Controls or Display:

If the controls or display on your Ninja vacuum are not functioning correctly, it can be challenging to adjust settings or monitor performance.

Possible Solution:

  • Check if the vacuum is properly connected to a power source. Loose connections may cause control issues.
  • If the control panel or display is unresponsive, try resetting the vacuum by turning it off, unplugging it, and then plugging it back in.
  • Consult the user manual for troubleshooting steps specific to your model. If the problem persists, contact Ninja customer support for assistance.

Let’s explore the pros and cons of Ninja Vacuums to help you make an informed decision before purchasing one for your home.

Pros of Ninja Vacuums:

Powerful Suction:

One of the standout features of Ninja vacuums is their impressive suction power.

They are equipped with high-performance motors that can effectively pick up dirt, pet hair, and other debris from various surfaces, including carpets, hardwood floors, and upholstery.

The strong suction ensures a thorough cleaning experience.

Versatile Cleaning Modes:

Ninja vacuums often come with multiple cleaning modes, such as standard mode for everyday cleaning, deep clean mode for tackling stubborn dirt, and even a handheld mode for above-floor cleaning.

This versatility allows you to adapt the vacuum’s performance to different cleaning tasks and surfaces.

Advanced Filtration Systems:

Many Ninja vacuums incorporate advanced filtration systems, such as HEPA filters, which can capture microscopic particles, including allergens, pollen, and pet dander.

This makes them an excellent choice for households with allergies or respiratory sensitivities, as they help maintain cleaner and healthier indoor air quality.

Innovative Technology:

Ninja vacuums often feature innovative technologies aimed at enhancing the cleaning experience.

These may include features like smart sensors that automatically adjust suction power based on the surface being cleaned or self-cleaning brush rolls that prevent hair and debris from getting tangled.

Large Dust Capacity:

This is especially beneficial for larger homes or those with pets, where more debris is likely to be collected.

Cons of Ninja Vacuums:

Heavy and Bulky:

Some users may find Ninja vacuums to be heavier and bulkier compared to other vacuum cleaner models.

This can make manoeuvring and storing the vacuum more challenging, particularly in smaller living spaces or when navigating tight corners.

Limited Availability of Parts:

While Ninja vacuums are widely available, there may be limitations when it comes to finding specific replacement parts or accessories for certain models.

This can be frustrating if you need to replace a component or expand the functionality of your vacuum.

Price Range:

Ninja vacuums generally fall in the mid to higher price range compared to some other vacuum brands.

While they offer advanced features and performance, the cost may be a consideration for budget-conscious consumers.


Ninja vacuums have garnered a reputation for their powerful suction, versatile cleaning modes, and advanced filtration systems.

They are equipped with innovative technologies that make the cleaning process efficient and effective.

However, potential buyers should be aware of the bulkiness, noise level, and potentially limited availability of parts.
