Hi @Radhika,

Thanks for letting us know about this. We’d recommend taking a close look at the underside of the motorised cleaner head - 

• Sometimes residue can build up on the soleplate of a vacuum cleaner from frequent contact with floor surfaces. Check the soleplate is clean and free of any residue. To clean it, give it a wipe with a damp cloth, but please do not wash or submerge any part of the cleaner head.
• Inspect the soleplate for damage - there should be no sharp corners or broken edges.
• Check there are no clinging particles of grit, trapped small stones etc.
• Make sure the small rollers on the soleplate can rotate freely.

As long as the soleplate is clean, free of damage and can roll freely over the floor surface, we wouldn’t expect any issues.

If you’re concerned there’s something wrong with the cleaner head after checking it, please get in touch with our experts via Live Chat through our Digital Assistant. Once you’ve clicked the round purple button on Dyson.com you can start a conversation with an agent by clicking the agent icon at the bottom left of the chat window. 

Hope this helps!
