For the experienced guys on here, does anyone actually use / run backpack's for gum removal ??
Considering offering a Maint service after a deep clean, backpack's will solve usual problems if gum / paving is maintianed on a regular basis / contract.
If you do use them could you share running costs, we would only use these on maint cleaning hence gum would be as low 2 peices /m2
Thank you in advance
