If you're thinking of starting a pool cleaning service, there are a few things you should know. First, it's important to research the competition in your area. What are they charging? What services do they offer? What are their hours?
Second, you'll need to have the right equipment. A good vacuum, for example, is a must. You'll also need chemicals and other supplies.
Third, it's important to be aware of the potential risks. These include liability risks, such as if someone is injured while using your service. There's also the risk of damaging pool equipment.
If you're willing to take on the risks, starting a pool cleaning service can be a great way to make money. Just be sure to do your homework first.
