Canisters FAQs

If the power goes off in the middle of cleaning, this may be due to the sensor that works to prevent the motor from over-heating. In this case, disconnect the power cord and ventilate for about two hours. This would be enough to restore the normal operations. The heat of the motor that rotates at a high speed with the force of the air sucked in should be used to cool down the motor, but if the dust canister, HEPA filter or the suction vent line (e.g. corded hoses or the main brush at the handle of the hose) is blocked, the suction power is weakened and the amount of air sucked in is also relatively small, making it difficult to cool the motor down.

If you experience the same symptoms even when connecting to another power socket, the product should be inspected by an engineer.

1. Depending on the cleaning style, even when the dust envelope is not full, the dust may block the air from being sucked in.
2. For models that use a HEPA filter, if the HEPA filter that cannot be washed in water is not replaced or if the HEPA filter that can be washed in water is not regularly cleaned, air cannot flow through, leading a decrease in suction power. 

Such HEPA filters have square borders in blue. They can be used for a year or a year and a half without being washed. But after this initial period, rinse lightly under running water and shake the water off. Repeat this 3-4 times and complete the washing within one minute. Dry the filter for 2-3 days in a shade until it is completely dry before re-using it. If washed like this every 2-3 months, the filter can be used for 3-4 years.

To prevent the main body from over-heating, the power is automatically turned off when the sensor to prevent over-heating is triggered. Please check the following.
1. Use a compressed blanket pack (Y or N) for 1-2 hours until the motor is sufficiently cooled off. The vacuum cleaner will resume its operation normally.
2. If the cleaner is used for a consecutive 20 minutes or more (Y or N) the power is automatically turned off when the sensor to prevent over-heating is triggered.
3. The heat of the motor that rotates at a high speed with the force of the air sucked in should be used to cool down the motor, but if the dust canister, HEPA filter or the suction vent line (e.g. corded hoses or the main brush at the handle of the hose) is blocked, the suction power is weakened and the amount of air sucked in is also relatively small, making it difficult to cool the motor down.
If any of the above does not apply, the cleaner should be inspected by an engineer.
