Does a Dyson Vacuum Scratch Hardwood?

Dyson vacuum cleaners are generally safe to use on hardwood floors. The key is to use the correct cleaning head suitable for your floor kind.

For example: 

• Dyson V8, V7, V6, HH08, SV06, SV09, SV10, SV11 models have a motorhead which uses a soft fluffy roller. Thats the best for hardwood, engineered wood floors.
  
• Dyson DC59, DC62, V6 came with a motorhead which had a traditional bristle based roller
  
  
• Dyson DC72 (V6 Digital Slim Animal Cordless), SV04 (V6 Cordless Stick Fuschia), SV06 (V6 Fluffy Cordless) and SV09 (V6 Absolute Cordless) came with a motorhead which was best for both hardwood as well as carpet as it had low bristle height and a smooth spindle kind of brushroll
  
  

So know what kind of flooring you have, the ratio of your carpeted area to hard floor / hard surface area and make a purchase decision based on that.

Always buy the one which best suits your need.

Once you have made a decision and brought a Dyson Vacuum home, make sure

• The wheels below the motor head and always in good condition, moving freely and free of an debri
• Always clean the rollers after a month of cleaning. Earlier if you are a daily cleaner
• Always make sure that the roller bristles are good and upright condition and make sure it rotates freely in the motorhead.

Just keeping a motorhead clean and free of any debris will make sure that the Dyson you bought does not scratch your valuable hardwood floors.
