Of course, you have long ago stuck the instructions for your vacuum cleaner somewhere: "And so everything is clear, why is it needed?" Alas, the instructions are written long and tedious, I don't really want to delve into them. We have collected the most common mistakes that make cleaning less effective and gradually kill your vacuum cleaner. Don't do that!
Do not switch the floor / carpet nozzle
The footswitch on the main nozzle does just that: when cleaning hard floors, the bristles must be used, which extends when the switch is pressed, and for carpets, the bristles must be removed. It's not just that a floor without bristles will scratch, but that there should always be a small distance between the nozzle and the floor so that air can move freely. The nozzle should not stick to the surface - this forces the engine to work at its maximum capacity and leads to overheating, the cleaning quality does not improve - dust and debris leave just with the air flow. The bristles help to create a gap between the nozzle and the hard floor, and on carpets this function is performed by the pile.
Switch the floor-carpet nozzle to improve cleaning performance
Always turn on the vacuum cleaner at full power
Research by manufacturers suggests that this is exactly the case: most consumers do not switch power, although more often than not, average power level is sufficient for cleaning.
Using only the highest power degrades the quality of cleaning (the nozzle can stick too much), overloads the engine, and contributes to deterioration of surfaces - furniture upholstery, books, curtains. Well, more electricity is consumed.
Most users only turn on the vacuum at full power. It is not right
Only high-pile carpets should be vacuumed at full power; hard floors and upholstered furniture - in the middle; books and curtains at minimum. Many manufacturers make vacuum cleaners with convenient power switches on the handle or with pictogram icons on the body: you can simply select the type of surface, the vacuum cleaner itself knows what power to turn on. Some models without electronic power control have a mechanical air flow control valve on the handle.
Inadvertently vacuuming wet
It may well be humid under the bathroom, and in the kitchen and hallway too. Happened? The vacuum cleaner will likely not respond in any way unless it is a puddle. And yet the consequences can be: from a short circuit in the most extreme case to "cementing" dust in the nozzle and the suction pipe, which leads to clogging and the formation of an unpleasant rotten smell, especially if you have a vacuum cleaner with a bag. By the way, this also applies to scattered cat litter: it can be wet and then create a lump that clogs the system.
This can only be done if you have a household or professional vacuum cleaner.
Remove construction debris, flour, debris
After renovation or just after drilling a concrete wall, of course, you need to vacuum it. How many vacuum cleaners died a brave death after such procedures is unknown, but it is definitely a lot. For cleaning construction waste, professional or household vacuum cleaners are suitable, in which the filtration system is simpler than in household ones, and a metal or plastic tank is used as a waste container. Sometimes, to clean up construction waste after repairs, a cheap vacuum cleaner is simply bought, which is not a pity to throw it away or move to the garage. Cleaning of fragments is contraindicated for bag vacuum cleaners - the bag may break; and cleaning a large amount of flour (for example, if a bag is dropped and it breaks) will damage any vacuum cleaner: all filters will clog and some of the flour can get into the motor - its particles are too small and pass through the filter pores. If you need to vacuum a small amount (no more than a tablespoon), then no problem.
Dragging the vacuum cleaner hose
It's simple: it can lose its tightness. Very carefully and not jerkily move the vacuum cleaner by the hose-you can, but pull-no. Better yet, use a carrying handle.
