No. Dust bags should be used only once because they are mode of a porous material. These pores will be clogged with dust and dirt even if you empty the dust bag. Using dust bags more than once may damage your vacuum cleaner in the long run. It may also lead to a drop in your appliance’s performance. 

Every Beko vacuum cleaner has a unique serial number. The location of the factory sticker changes depending on the model of your appliance. Canister and barrel vacuum cleaners' serial numbers are located under the appliance. Upright and cordless vacuums have their serial number stickers at the back or on the handle of the appliance. 

You can only use water filtered vacuum cleaners or vacuums with carpet cleaning functions to suck up liquids. Other models may get damaged if you try to vacuum over wet surfaces.

Vacuum cleaners are designed to pick up ordinary household dust and dirt. Big, hard and pointy items may clog or damage your appliance. That’s why you should not vacuum things like construction debris, cement dust, pins, and hairclips. Unless you own a water-filtered vacuum cleaner or one that has a carpet cleaning function, you should not use vacuum wet spills either.

Although indoor vacuum cleaners are not designed to be used outside, you can use them as long as you don’t pick up hard items and do not overfill the dust bag or container.

If your vacuum has a pull and release cord system, pull the cord until it stops extending and let it go. If it has a cord rewind function, pull the cord until it stops extending and press the rewind button. If only one part of the cord is retracting, try pulling the cord and releasing it again. If the problem persists, contact an authorised service agent.
