To collect the rare amounts of water in the desert as quickly as possible before the water evaporates.
The advantages of a plant with roots that grow down are that it helps to stabilize the plant and to hold it in place. It also allows the plant to find water, which is not always close to the surface.
Cactus roots have adapted by burrowing deep to reach water that is not quickly evaporated by surface heat. The stems grow very thick to act as a sort of insulation against evaporative loss. And the leaves have evolved as needles which have a low surface area to reduce evaporation and to deter animals and insects that would pierce the stem to suck moisture from the plant.
It is important for the roots of desert plants to grow near the surface of the ground so the desert plant's roots may get water easily ( without going into many kinds of trouble ).

A desert cactus can grow where the soil is free drainingbut holds enough moisture to meet cactus needs. It can grow where heat and light levels are high and moisture levelslow. A jungle cactus can grow where there are tall tree trunks or branches on which to anchor their airy, exposed roots. It can grow where heat and humidity levels are high and light levels low. But neither desert nor jungle cactus plants can grow in cold, damp climates.

Cactus roots go to the surface because in desserts, the water is very little and only at the surface. When it rains, it will be able to collect the water as the rain falls down.
