A Dyson Ball Animal 3 that has become louder or has started to whine, rattle or grind is telling you about airflow or a loose part, and each sound points to a different cause. A high-pitched whine usually means air is starved: the filter is dirty, the bin is full or the hose is partly blocked, and the motor runs faster to compensate. Empty the bin, check the hose and wand for a blockage and wash the filter, letting it dry completely for a day before it goes back.
The checks in more detail
A rattle suggests something small, such as a coin, a stone or a button, has been drawn into the floor head, the brush bar housing or the cyclones, so unplug the machine and inspect the head and the wand openings. A grinding or scraping sound is often the brush bar. Hair wrapped round the ends, a worn bearing or debris stuck beneath the bar rubs and growls on bare floors. Lay the head on its side, cut away wrapped hair with scissors, turn the bar by hand and feel for roughness; a bar that does not turn smoothly needs cleaning or replacing.
A thumping noise on carpets can be the brush bar striking a thick rug, and switching the bar off for hard floors reduces noise. Check the drive belt on the machine's floor head, if your model has one; a loose or stretched belt slaps. Make sure the bin and the wand click in firmly, since a bin that is not seated rattles. The motor itself can become noisy with age, and a motor that screams even with a clear path, a new filter and a clear brush bar may have worn bearings.
If you smell burning, switch it off at once and unplug it. Do not run the machine with a wet filter, and do not run it without the filter, because dust gets into the motor and shortens its life. If the noise stays after the checks, record a short video so that Dyson support can hear it and contact them with the serial number. A machine in warranty is repaired free, and an older one can be repaired for a charge, so ask for the options.
