Generally speaking, Dyson vacuums are made to operate on a range of surfaces, including hardwood floors. Many models come with specific attachments or settings destined to optimize cleaning on hardwood surfaces.
These often include soft brush heads designed to pick up dust and debris without scraping the wood. Additionally, some models let you switch off the brush roll to prevent debris from being dispersed and maybe causing scratches on delicate floors.
For the best results, it’s important to refer to the specific model’s manual and use the recommended settings and attachments for hardwood floors.
