I use a Dyson stick on my hardwood floor. It is version 8, so just has one type of head and it does not scratch my floor. Hope that helps.

This is the head I’m using. Everything is rolling as it should. I’m just wondering if the stones get stuck on the sides or in front of the rear roller. It’s the only thing I can think of.

Are the rollers down. You have them up for carpet

This head is specifically for hardwood floors. Can’t alter anything.

Maybe you need to spend $30 on a decent entry door mat, so the shoes are cleaned of stones,and dirt before entering your beautiful floors.

I had exactly the same thing happen with my floors, though I didn't care as we were just about to renovate. I use a Dyson ball version. I changed the head to the hard floor option and no problem now.

Shoes are removed before entering the house and mat at the door so those bases are covered but stones still get tracked in.

I use the hardwood head but the stones get caught and dragged in the felt underneath.

I’ve just resorted to the old fashioned broom. Slower but no risk of scratching.

Hi there we have found best thing is no vacuum. We use Enjo dust mop, dustbuster to get that up in the corners then damp Enjo floor mop. Cleans beautifully and no damage over many years.

I agree Enjo range for the floor. Had no issues with beautiful timber in 14 years.
