- Try the free checks first. A full bag, blocked hose or clogged filter causes most “broken” vacuums.
- Stop using it if you smell burning or see sparks, and unplug it.
- Quality machines are worth fixing. Well-built vacuums are designed to be serviced and repaired.
- Rough rule: if the repair costs more than about half the price of a comparable new vacuum, replacing usually makes more sense.
- Not sure? Bring it in and we’ll give you an honest answer.
Your vacuum has lost its pull, started making a strange noise or simply won’t turn on. Before you throw it out, it’s worth knowing that many problems are quick and inexpensive to fix, and some you can sort yourself in five minutes. Here’s how to work out whether to repair or replace.
Free checks to try first
Always unplug the vacuum (or remove the battery) before checking anything.
- Empty the bin or change the bag, even if it doesn’t look full. Fine dust can block a bag long before it’s visibly full.
- Clean or replace the filters. A clogged filter is the number one cause of weak suction.
- Check the hose for blockages. Disconnect it and look through it, or drop a coin through to see if it comes out the other end.
- Clear the brush roll. Cut away wrapped hair and thread so it spins freely.
- Check the floor head and wand for socks, tissues or toys stuck inside.
- Let it cool down. If it cut out mid-clean, it may have overheated because of a blockage. Clear it, wait 30–60 minutes, and try again.
Signs your vacuum needs a professional
| What you notice | Likely cause | What to do |
|---|---|---|
| Burning smell | Worn or slipping belt, jammed brush, or a motor issue | Stop using it and get it checked |
| Brush roll not spinning | Broken belt or a fault in the powered head | Often a simple repair |
| Weak suction after cleaning filters and checking for blockages | Hidden blockage, worn seals or a tired motor | Book a service |
| Loud whining or rattling | Something caught in the fan, or worn motor bearings | Stop using it and get it checked |
| Cuts out or won’t turn on | Damaged cord, switch fault, or a battery issue on cordless models | Don’t use a damaged cord; get it checked |
| Cordless runs for only a few minutes | Battery worn out | A replacement battery may be all it needs |
When repairing makes sense
- It’s a good-quality machine. Well-made vacuums are designed to be repaired and serviced, and can run for many years with the right care.
- The fault is a common part like a belt, brush roll, hose, switch or battery.
- Parts are available for your model.
- You like your vacuum and it otherwise does the job well.
- You’d rather keep it out of landfill. Repairing is the more sustainable choice.
When replacing makes more sense
- The repair would cost more than about half the price of a comparable new vacuum.
- Parts for your model are no longer available.
- It’s had several faults in a row and is showing its age.
- Your needs have changed, for example a new home, new floors or a new pet.

Frequently asked questions
Is it worth repairing an old vacuum?
Often, yes, especially a good-quality machine with a common fault such as a belt, hose or brush roll. If the repair costs more than about half the price of a comparable new vacuum, replacing usually makes more sense.
Why has my vacuum lost suction?
The most common causes are a full bag or bin, a clogged filter, or a blockage in the hose or floor head. Check these first, with the vacuum unplugged.
Why does my vacuum smell like burning?
Usually a worn belt or a brush roll that’s jammed with hair. Stop using it, unplug it, and have it checked to avoid further damage.
Can you replace the battery in my cordless vacuum?
For many models, yes. Bring it in or call us with the make and model, and we’ll check what’s available.
