If your vacuum cleaner loses suction, makes unusual noises, has a burning smell, or shows blockages, it likely needs servicing to maintain optimal performance.
Your vacuum cleaner is one of the hardest working appliances in your home. When it starts showing signs of wear, don’t ignore them. Catching problems early can save you money and extend your vacuum’s lifespan significantly.
1. Loss of Suction Power
When your vacuum isn’t picking up dirt like it used to, it’s trying to tell you something. Before calling for service:
- Check for full bags or clogged filters
- Inspect hoses for blockages
- Look for cracks in the vacuum body
If you’ve checked these and suction remains weak, your vacuum may need professional attention. The motor might be failing or there could be an air leak in the system.
2. Strange Noises
All vacuums make noise, but new sounds signal trouble:
Common Problem Sounds
| Sound | Likely Cause |
|---|---|
| High-pitched squealing | Worn motor bearings |
| Grinding or rattling | Damaged fan blades |
| Loud humming | Blocked airflow |

3. Burning Smells
A burning odor is never normal and indicates immediate service is needed. Common causes include:
- Overheating motor
- Frayed electrical wiring
- Clogged filters restricting airflow
According to Consumer Reports, overheating is the leading cause of premature vacuum motor failure.
4. Frequent Clogs
If you’re constantly clearing blockages, your vacuum may have:
- Damaged hose with internal obstructions
- Faulty suction pathway design
- Incorrect attachment for your flooring type

5. Electrical Problems
Watch for these warning signs:
- Intermittent power loss
- Spark when plugging in
- Tripped circuit breakers
Electrical issues pose fire hazards and should be addressed immediately by a professional.
6. Excessive Vibration
While some vibration is normal, excessive shaking can indicate:
- Unbalanced brush roll
- Loose internal components
- Worn motor mounts
Continued use in this state can cause additional damage to other components.
7. Visible Damage
Inspect your vacuum regularly for:
- Cracked housing
- Frayed power cords
- Damaged wheels or brushes
As noted by Good Housekeeping, physical damage often leads to more serious internal problems if left unrepaired.
Preventive Maintenance Tips
Extend your vacuum’s life between professional services:
- Empty bags or canisters when 2/3 full
- Clean filters monthly (replace as needed)
- Inspect brushes for tangled hair/debris
- Check hoses for obstructions
- Store properly to prevent cord damage
When to Service vs. Replace
Consider professional service if:
- Your vacuum is under 5 years old
- Repair costs less than 50% of replacement
- It’s a high-end model with available parts
For older or low-end models, replacement may be more cost-effective. Our best vacuum for carpet and hardwood floors guide can help you choose a suitable replacement.
