Operating Instructions
Learn how to effectively use your cordless upright vacuum cleaner:
- Power On/Off: Press the power button (Controller Type: Push Button) located on the main body to turn the vacuum on. Press it again to turn off.
- Cleaning Modes: Your vacuum may have different suction modes. Refer to the specific button on the handle or main body to switch between modes (e.g., standard, max).
- Charging: When the battery indicator shows low power, connect the vacuum to the power adapter and charge it fully. Avoid over-discharging the battery for optimal lifespan.
- Using Attachments: For specific cleaning tasks, detach the extension wand and attach specialized nozzles or brushes directly to the main vacuum body (if included, not specified in package contents but common for vacuums).
Maintenance
Regular maintenance ensures optimal performance and extends the lifespan of your vacuum cleaner.
Emptying the Dustbin
- Ensure the vacuum is turned off and unplugged from charging.
- Locate the dustbin release button, usually near the dustbin. Press it to detach the dustbin from the main body.
- Over a trash can, open the dustbin lid and empty the contents.
- Close the dustbin lid and reattach it to the main vacuum body until it clicks into place.
Cleaning Filters
The filters should be cleaned regularly, typically after every few uses, or when suction power decreases.
- Remove the dustbin as described above.
- Carefully remove the filters from the dustbin. Tap them gently over a trash can to remove loose dust.
- If filters are washable (check product specifications or markings on filters), rinse them under cold running water until the water runs clear. Do not use detergent.
- Allow filters to air dry completely for at least 24 hours before reinserting them. Do not use a dryer or heat to dry them.
- Once completely dry, reinsert the filters into the dustbin and reattach the dustbin to the vacuum.
Cleaning the Brush Roll
Periodically check the brush roll for tangled hair or debris.
- Turn off the vacuum and disconnect it from any power source.
- Flip the floor brush head over. You may need to use a coin or screwdriver to unlock the brush roll cover.
- Remove the brush roll. Use scissors to cut away any tangled hair or threads.
- Clean any debris from the brush roll housing.
- Reinsert the brush roll and secure its cover.
