A pool cleaner and a trampoline are two of the bigger backyard purchases before an Australian summer. Pool cleaners differ mainly in where their power comes from: a robot has its own motor and filter, while a suction cleaner runs off the pool pump. Behind the cleaner sit the pump, filter, chlorinator and heater, and in Sustainability Victoria's pool pump trial the pump used about three-quarters of a pool's electricity. Trampolines differ in how the mat is held, by coil springs, leaf springs or flexible rods, and in how long the warranty covers each part.

Safety around the trampoline

The ACCC's trampoline guide advises supervising children and allowing one child on at a time, and notes there is no mandatory Australian standard for trampolines. Kidsafe Victoria recommends at least 2.5 metres of clear ground around a trampoline.
