Common faults and maintenance skills of vacuum cleaners

Will the suction power of the vacuum cleaner drop?

Yes, the suction power of every vacuum cleaner will decrease during long-term use, even the dyson, which claims that the suction power does not decay.
A large part of the reasons are related to product design, and part of the reasons are related to consumers' personal habits.

Picking a good vacuum cleaner and developing a good use habit can delay this problem. APOSEN vacuum cleaner is a good choice, they have all kinds of vacuum cleaners, such as: Cordless Vacuum Cleaner、Corded Vacuum Cleaner、Robot Vacuum、Handheld Vacuum Cleaner and so on.

If your vacuum cleaner loses its suction power, or the vacuum cleaner stops working completely, in many cases, it is not that the vacuum cleaner is broken, but that there is a problem with your use. We have the opportunity to restore the suction power through some necessary cleaning.

The use of vacuum cleaners has been very common, but many people do not know how to deal with some problems that arise during use. This article will take everyone to understand the common faults and maintenance methods of vacuum cleaners, and I hope it can help you.

Common faults and maintenance of vacuum cleaners

What to do if the motor doesn't rotate

The cause of the motor not rotating is nothing more than a circuit break, poor contact and damage to the motor itself.

Since the circuit of a general vacuum cleaner is relatively simple, it is not difficult to find out where there is an open circuit or poor contact. Usually, the failure of the power switch, fuse tube, power reel or poorly welded connection is more common.

1. If the fault is found on the power switch, it is mostly caused by poor contact of the switch.

In the inspection, pay special attention to whether the contact of the reel is good or whether the wire is broken, because the installation position of the reel is usually hidden, and the disassembly and assembly are more troublesome and easy to be ignored.

2. If the fuse tube is blown, be sure to find out the cause, and replace it with the same specification fuse tube after

troubleshooting, otherwise it is likely to blow the fuse again or damage the motor.

If the fuse tube is still blown when replaced again, do not replace it again, let alone try to replace the fuse with a larger rated current, because this will easily damage the motor.

The correct method is to thoroughly check the cause of the burning fuse. Practice shows that if the circuit has no obvious short-circuit point, the cause is mostly motor overload, which can be checked.

3. If there is no problem in the inspection circuit and the fuse tube is normal, then the fault lies in the motor, which is generally a fault of a broken wire or poor contact.

Wire breakage usually occurs on the lead wire of the motor, which can be seen by naked eyes. If it is difficult to judge, use a multi meter to test.

What should I do if the vacuum cleaner has low suction power?

1. Due to poor suction air duct.

If any one of the ventilation ducts (paths) from the suction nozzle to the motor exhaust hole is blocked, the dust suction air volume will be reduced and the suction power will be insufficient.

The main reasons for the blockage of the air duct: First, the vacuum cleaner has sucked larger objects. Second, the dust filter bag is stained with too much dust, too much dust in the dust collection chamber or the dust cover is damp, making it difficult for air to circulate.

For the former, the problem can be solved simply by removing the foreign matter in the air duct of the vacuum cleaner. If it is the latter, remove the dust in the dust chamber first.

Then dispose of the filter bag. If it is a disposable product, it should be replaced in time; if it is a cloth filter bag, it can be eliminated by cleaning the filter bag.

Namely: first soak the dust filter bag with clean water for 30-60 minutes, then repeatedly scrub, rinse with clean water, and use it after drying.

Generally, do not wash the dust filter bag with soap, or put it in the washing machine or wash it vigorously with your hands. This will easily make the flannel lint, and dust will easily penetrate into the motor, which may affect the normal operation of the motor over time, and even cause the motor to be burned.

2. Due to air leakage from the air duct.

This failure is mainly caused by damaged or improper installation of the dust filter, rupture of the flexible connector, and loose or misaligned connection between the nozzle and the connector.

Different situations can be distinguished by repairing or installing the dust filter, or connecting the suction nozzle and the pipe tightly.

If the hose is broken and leaks, it can be repaired with Biohit glue or bandaged plastic tape. For serious damage, replace it with a new one.

3. Reasons for motor speed.

The main reason for the slow motor speed is the poor contact between the brush and the commutator.
During inspection, the resistance at both ends of the motor can be measured with a multimeter R×1 gear, and it should be 8-10Ω in normal condition.

If the measured value is much larger than this, it can be judged as poor contact. If the measured value is too large, or even disconnected, the motor will not start, instead of slow speed.
