There are several reasons for your vacuum cleaner to lose its suction power. Please see if one of the following will solve the problem.
Check the dust container
If your vacuum cleaner has lost suction power, it’s time to empty the container.
See if the filters are clogged
Vacuum cleaners come with various foam or mesh filters. These might get clogged over time if not cleaned or replaced properly. This will cause your vacuum to lose suction. For general outlines about how to take care of your vacuum cleaner filters, see here.
For more information on your vacuum cleaner’s filters, please consult your user manual. If you’re having trouble finding your manual, download it here using your product’s model number.
Check the hose for blockage
A blocked hose will cause your vacuum to lose suction. Take the hose and attachments apart to see if there is a foreign item, a dust or hair ball restricting the air flow. You can unblock the hose with the help of a long stick or a broom handle.
Check the hose for cracks or tears
Check the hose for any damage as air seeping through a crack or tear will cause loss of suction. If you do find a tear, contact an authorised service agent.
Check the brush or roller for clogging
Turn the brush upside down and clean the brush or roller. Over time, these might get clogged or stuck because of dust or hair and cause your vacuum cleaner to lose suction. Some brushes can be taken apart for easier cleaning. For parts that can be disassembled, consult your user manual as each model may have different instructions. If you’re having trouble finding your manual, download it here using your product’s model number.
Make sure all parts are attached properly
Loose connections will cause your vacuum cleaner to lose suction. Make sure that the dust container, the hose, the tube and the brush are all attached properly.
Consider technical problems
If the problem continues, your vacuum cleaner might have a technical problem. If you suspect this to be the case, contact an authorised service agent.
