If you are wondering about the different loud noises of your VK7 battery vacuum cleaner, don't worry, in most cases this is normal.
The VK7's intelligent motor protection system automatically adjusts the vacuum's power level to ensure the best cleaning experience. These adjustments may cause the vacuum to emit different sounds depending on what surface you are cleaning or how much dust and dirt is present.
However, if you notice that the vacuum cleaner's performance does not increase despite increasing the suction level, this may indicate a problem with the airflow or the filter. It is then advisable to check the airways and the premium filter for blockages. A blocked duct or a full dust bin can also cause unusual noises.
When vacuuming on upholstery, it's best to move the nozzle back and forth to make sure the vacuum's performance is optimal. It is also important not to store the cordless vacuum cleaner in very warm places, as this can shorten the life of the device.
Overall, it is important to perform regular maintenance on your VK7 cordless vacuum cleaner to ensure that it remains in perfect condition and that you can always enjoy a clean home.
