If you notice a strange noise from your vacuum cleaner during operation, it could be due to the blade part not being assembled properly or other accessories not being wiped clean. Another reason for the noise could be due to the parts shifting during handling or collision, causing the motor to rotate at high speeds and create friction noise. Ensure that all parts are secured properly during assembly and check for any debris that may be causing blockages.
One option for addressing a malfunctioning vacuum cleaner is to disassemble it yourself and inspect the individual parts for any signs of damage or resistance. This can involve checking for any instances of collision or friction that could be causing the issue. Alternatively, another approach would be to take the vacuum to a repair shop for further diagnosis and professional attention.
A possible rephrased version could be:
The blade's bearing can cause trouble if it is not well lubricated or too worn out. If you notice the bearings being loose, it is best to replace the rotor promptly. Likewise, if the wind impeller is compressed and the nut is not tight enough, it can cause the blade wheel shaft to move out of position and hit the shell. In such cases, you should fix the impeller's position before securing the nut again.
3. The muffler component of the vacuum cleaner is broken. The muffler layer of foam plastic is generally found around the casing of the vacuum cleaner. If there is, use 303 glue to bond again. If there is damage, you can subsidize a piece again.
When the suction channel of the vacuum cleaner is obstructed, the host may show signs of no load, operate at an excessively high speed, and produce a louder, duller noise. In such a situation, it is crucial to check the dust level indicator and immediately shut down the machine and unplug it if it is at its limit. Even if there is no indicator, it is important to listen for any unusual sounds and shut down the machine to check if the channel is blocked.
