Claim 0:
1. A method for reminding a replacement of a filter of a vacuum cleaner, comprising:
obtaining a rotating speed difference of a motor within a set time interval;
comparing, according to a working parameter of the vacuum cleaner, the rotating speed difference with a preset rotating speed difference threshold, to obtain a comparison result; and
reminding a user to replace the filter according to the comparison result;
wherein the working parameter of the vacuum cleaner comprises: a non-constant motor power operating parameter, and the comparing, according to a working parameter of the vacuum cleaner, the rotating speed difference with a preset rotating speed difference threshold, to obtain a comparison result, comprises: comparing, according to non-constant motor power operating parameter, the rotating speed difference with the preset rotating speed difference threshold, to obtain the comparison result; and wherein the non-constant motor power operating parameter is set when the motor is in a non-constant power operating mode, when the motor in the non-constant power operating mode is working, a rotating speed of the motor changes with a power supply voltage from time to time; and a modeling between the power supply voltage and the rotating speed is performed for different power supply voltages.
