Requirements vary by booking. Always read the job details before you accept.
When you bring supplies
Some jobs require you to bring standard cleaning products (kitchen, bathroom, glass, disinfectant, etc.). The listing will say if supplies are required. Bring only products you are trained to use safely.
Equipment
Vacuums, mops, and buckets are often provided by the customer unless the job states otherwise. If something essential is missing on arrival, message the customer through Instaclean before starting.
