Mod­ern require­ments for house­hold appli­ances set quite strin­gent require­ments for the per­mis­si­ble noise lev­el. That is why, if the noise lev­el of a work­ing vac­u­um clean­er has become sig­nif­i­cant­ly high­er, then this should be a sig­nal that it requires addi­tion­al atten­tion.

The main source of noise when a vac­u­um clean­er is run­ning is the engine. An increase in the vol­ume of a run­ning engine indi­cates that it is oper­at­ing at increased pow­er. Pro­longed oper­a­tion in this mode leads to over­heat­ing of the engine, which is evi­denced by an increase in the tem­per­a­ture of the air leav­ing the vac­u­um clean­er. This can lead to engine fail­ure and sub­se­quent cost­ly repairs.

Causes of a loud vacuum cleaner

There are sev­er­al main rea­sons why the vac­u­um clean­er began to work loud­ly.

Over­flow­ing dust­bin — one of the most com­mon caus­es, espe­cial­ly for old­er mod­els. The dust bag can hold a cer­tain amount of debris and needs to be changed peri­od­i­cal­ly for dis­pos­able dust bags or cleaned (for reusable rag bags). An accept­able fill­ing lev­el is around 80% of the vol­ume, then the fil­ter­ing abil­i­ties of the bag are sig­nif­i­cant­ly reduced, the suc­tion pow­er drops, and the engine starts to work at the pow­er lim­it. In mod­ern mod­els of vac­u­um clean­ers, there is a spe­cial light indi­ca­tor that gives a sig­nal about an over­flow­ing dust con­tain­er.


Do not reuse a dis­pos­able bag — it has low strength and a short ser­vice life. It can break at any time and all the debris and dust will fall into the engine com­part­ment, which can cause seri­ous dam­age. Reusable bags need to be washed to improve their air­flow per­me­abil­i­ty.

Clogged fil­ters — mod­ern vac­u­um clean­ers have a mul­ti-stage air purifi­ca­tion sys­tem, pre­mi­um seg­ment vac­u­um clean­ers with HEPA fil­ters are able to cap­ture up to 95–99% of con­t­a­m­i­nants. When used for a long time, the fil­ters become clogged, so addi­tion­al pow­er is required so that air can pass through them. Some fil­ters (main­ly foam, coarse) can be washed and they will almost com­plete­ly restore their fil­ter­ing abil­i­ties.

for­eign objects – the suc­tion of the vac­u­um clean­er may be weak­ened due to balls of dust, large pieces of paper or debris, toys and oth­er objects that will inter­fere with the free pas­sage of air flow into the hose.

Tech­ni­cal mal­func­tion – Loud engine oper­a­tion can be caused by worn bear­ings. If you do not car­ry out time­ly and com­plete clean­ing of the fil­ter sys­tem, dry dust pen­e­trates into the engine com­part­ment, set­tling on mov­ing parts. As a result, the coef­fi­cient of fric­tion sharply increas­es, if the bear­ings are not lubri­cat­ed in time, they begin to work vir­tu­al­ly “dry”, which leads to their wear. It is much worse if the prob­lem is caused by a wind­ing mal­func­tion or com­po­nent fail­ure. In this case, you will have to con­tact the ser­vice cen­ter.


If, when you turn on the new vac­u­um clean­er, it imme­di­ate­ly starts to work very loud­ly, you should imme­di­ate­ly con­tact the ser­vice cen­ter. With a high prob­a­bil­i­ty, it can be argued that the prob­lem is relat­ed to a man­u­fac­tur­ing defect, so such a vac­u­um clean­er can be exchanged.

The vacuum cleaner hums strongly: what can be done

If the vac­u­um clean­er began to buzz strong­ly, then what can be done so as not to call the mas­ter? For starters, sim­ply dis­con­nect the hose from the vac­u­um clean­er. If the engine stops mak­ing noise, then a block­age has formed either in the hose or in the brush / noz­zle. You can clean the hose your­self by using a cable that plumbers use when clean­ing sew­ers. In addi­tion, it is nec­es­sary to clean the brush, on the vil­li of which wool, hair, dust and oth­er debris accu­mu­late. All this leads to the fact that the air is poor­ly absorbed, the thrust weak­ens, it is nec­es­sary to increase the engine pow­er.


Before car­ry­ing out work, be sure to de-ener­gize the vac­u­um clean­er by dis­con­nect­ing it from the mains.

If the vac­u­um clean­er con­tin­ues to make noise, it is nec­es­sary to clean and replace the fil­ters. In this case, it is nec­es­sary to clean the dust and the body of the vac­u­um clean­er:

  • The cham­ber in which the dust col­lec­tor is locat­ed must be wiped with a damp cloth and any debris accu­mu­lat­ed there must be removed.
  • Clean all cracks, ribs, nich­es on the body of the vac­u­um clean­er where dust can accu­mu­late.
  • Inspect the place where the dust col­lec­tor is attached — it must be clean, dust and sand par­ti­cles will inter­fere with the tight attach­ment of the dust bag. Through leaks, dust will enter the motor, caus­ing increased wear on the bear­ings.
  • Blow out the engine com­part­ment by remov­ing the dust col­lec­tor. At the same time, the body must be tilt­ed in dif­fer­ent direc­tions, chang­ing the suc­tion pow­er — this will get rid of debris and dust that have fall­en into the engine com­part­ment.

If after that the engine con­tin­ues to make noise and does not suck up dust well, you should con­tact a ser­vice cen­ter.

Before using the vac­u­um clean­er, check that all parts are in place, the fil­ters fit snug­ly and there are no gaps through which dust can enter the engine com­part­ment. In addi­tion, loose parts due to vibra­tion will cause addi­tion­al noise, and may fail over time.
