Cordless stick vacuums are convenient, but they're also small machines with small bins, fine filters and a battery that ages. When suction drops, the cause is almost always a full bin, a clogged filter or hair wrapped around the brush — all things you can fix in a few minutes. A regular routine keeps it running like new and extends its life.
Weekly routine
Empty the dust bin
A bin past the max line chokes airflow. Empty it over a bin bag, and wipe the inside with a dry cloth.
Tap out the pre-filter and cyclone
Dust builds on the mesh or cone around the cyclone. Tap it clean, or brush it gently.
Check the brush roll
Hair and threads wrap around the brush and stop it spinning freely. Many brush rolls pop out; cut along the groove with scissors and pull the hair off.
Monthly routine
Wash washable filters
Check the manual: many pre-filters and some HEPA filters can be rinsed in cold water only, with no soap.
Dry completely
Leave filters to air-dry for at least 24 hours, out of direct heat. Putting back a damp filter can damage the motor and cause musty smells.
Clear the wand and nozzle
Look through the wand for blockages; a coat hanger or broom handle can push out stuck debris gently.
Wipe the sensors and wheels
Some heads have dust sensors or LEDs; a dry cloth keeps them working.
Battery care
- Avoid heat. Don't charge or store it in direct sun or next to a radiator.
- Use the boost mode sparingly. Max power drains the battery fast and generates more heat.
- Long storage: leave it around half charged rather than full or empty.
- Use the original charger and replace the battery with an approved one when runtime drops significantly.
Troubleshooting
Suction has dropped
- Symptom
- Weak pickup, even on max.
- Likely cause
- Full bin, clogged filter or a blockage.
- Try
- Empty the bin and tap out the filters.
- Check the wand, nozzle and inlet for blockages.
- Replace filters that stay grey after washing.
The brush won't spin
- Symptom
- The head moves but the roller doesn't turn.
- Likely cause
- Hair wrapped tightly, or debris jammed in the end caps.
- Try
- Remove and de-tangle the roller, including the ends.
- Check the head's connection to the wand.
It cuts out or pulses
- Symptom
- The motor surges or stops.
- Likely cause
- Blocked airflow triggering overheat protection, or a low battery.
- Try
- Clear all filters and the airway; let it cool.
- Fully charge, then test again.
It smells musty or burnt
- Symptom
- An odour when running.
- Likely cause
- Damp filter, old debris in the bin, or hair burning on the roller.
- Try
- Dry filters fully and wipe the bin.
- De-tangle the brush roll. If it smells of burning electronics, stop using it and contact support.
