Despite James Dyson’s claim that his firm has “an acoustics team that spend all day, every day analysing noise and vibration levels,” the Dyson vacuum cleaner is, as anyone who’s ever used one will know, relatively noisy compared to other machines on the market. The extra noise is due to Dyson vacuum cleaners working differently to the more traditional varieties.
The fan of a Dyson vacuum rotates at 35,000 rpm, according to the Times Online. It is this rotation that is responsible for the loud noise that even fully functioning machines produce. According to the Allergy Control Products website, Dyson cleaners operate at a noise level of about 75 decibels. Even the machine’s inventor, James Dyson, admits that their loud noise “is a major area for improvement”.
Dyson cleaners may emit noises when the motor is damaged. A high-pitched noise can indicate the motor’s bearings are worn and need replacing. If the motor sounds relatively laboured, the motor itself may need replacing. It’s possible for the cleaner’s owner to repair or replace a damaged motor.
A loud ratcheting noise is a signal from the machine that the beater roller has become stuck or has been jammed by a foreign object. Alternatively, it may signal that the machine’s clutch has weakened or failed. Check the beater roller by unplugging the machine and removing the sole plate at its base. Inspect that the beater assembly is able to turn freely. Remove any foreign objects that prevent it from doing so.
According to James Dyson, “people care more about the machine's cleaning performance than they do about the noise.” This appears to be particularly true in the case of allergy sufferers. According to the PR Quick website, the noise created by the cleaners is a fair exchange for the machine’s ability to control allergens in the home. Despite its noise, the Allergy Control Products website recommends the Dyson line of vacuum cleaners as offering a total allergy and asthma vacuuming solution for the home.
