Snow foam - recommendations?

[rhysallison]

Just purchased a nilfisk c110, and I'm about to purchase this lance

Then I've heard bilt hamber are the guys for snow foam, is this the right snow foam product? Seems to be a lot cheaper than anywhere else

Otherwise if anyone else has recommendations on what snow foam to get it would be much appreciated

Thanks
