Short answer: Pick by area and pressure: fixed spray for small, low-precipitation beds; rotary (rotor) for medium-to-large lawns; impact for big areas and windy sites; MP Rotator for water-saving matched-precipitation coverage; and bubbler for trees and shrubs that need a slow soak.

Type comparison table
| Type | Coverage radius | Pressure need | Best for | Pros | Cons |
|---|---|---|---|---|---|
| Fixed spray | 5–15 ft (1.5–4.5 m) | 20–30 psi | Small lawns, beds | Even, cheap, simple | High GPM, wastes on wind |
| Rotary (rotor) | 15–50 ft (4.5–15 m) | 25–50 psi | Medium–large lawns | Low GPM, even | Slower to wet |
| Impact | 20–100 ft (6–30 m) | 25–60 psi | Large areas, wind | Tough, long throw | Noisy, high GPM |
| MP Rotator | 8–35 ft (2.5–11 m) | 20–50 psi | Water-saving lawns | Low GPM, low drift | Needs clean filter |
| Bubbler | 1–3 ft (0.3–1 m) | 10–25 psi | Trees, shrubs | Deep soak, no mist | Point use only |

Fixed spray heads
Fixed (or “spray”) heads emit a fan-shaped pattern that stays on constantly while running. They cover a fixed radius, typically 5–15 ft (1.5–4.5 m), and apply water fast — which means high GPM per head. They’re ideal for small, irregular lawn patches and narrow beds where a rotor can’t fit. The downside: high precipitation rate invites runoff on clay, and wind throws the fine spray off target. Use them only on small zones and keep them out of windy spots.
Rotary (rotor) heads
Rotors rotate a single or double stream in a full or part circle, covering 15–50 ft (4.5–15 m). Because they apply water more slowly than sprays, they use less GPM for the same area and are far gentler on slopes and clay soil. They’re the default for medium-to-large turf. Gear-driven rotors are quiet and common in homes; the trade-off is a longer runtime to deliver the same depth.
Impact sprinklers
The classic “tripod” or impact head — a swinging arm interrupts the stream to create the familiar ticking rotation. They throw far (up to ~100 ft / 30 m) and handle dirty water and wind better than most, which is why farms and big lawns use them. They’re noisy and draw high GPM, so they need a generous zone budget (see heads per zone). Best where coverage area is large and aesthetics/noise aren’t a concern.
MP Rotator
MP Rotator is a rotating, multi-stream, low-flow nozzle that replaces a standard spray nozzle on the same body. It throws several narrow streams in a slow rotation, cutting GPM by roughly half versus a fixed spray while keeping even coverage. That lets you put more heads on a zone and reduces runoff and misting. It needs clean water (a filter helps) and is the water-saver’s pick for lawns. For context on why efficiency matters, see our drip vs sprinkler comparison.
Bubblers
Bubblers don’t spray at all — they release a low, bubbling flow right at the base of a tree or shrub, soaking the root zone without airborne loss. Radius is just 1–3 ft (0.3–1 m), pressure 10–25 psi (0.7–1.7 bar). They’re the sprinkler-family answer for woody plants and are often used in the same valve zone as drip. Great for deep, targeted watering; useless for open lawn.

How to choose
- Measure the area and your available GPM at the source. That sets how many heads a zone can carry.
- Small, tight lawn or bed (<15 ft throws): fixed spray.
- Open lawn, medium to large: rotor, or MP Rotator if you want to save water.
- Very large or windy site: impact.
- Trees and shrubs: bubbler (or drip) on a separate zone.
- Match precipitation rates within a zone — don’t mix fixed sprays and rotors on the same zone, or one area floods while another stays dry.
Program the zones by type with a controller — our controller programming guide explains scheduling each head type.
FAQ
What’s the difference between a spray and a rotor head? A spray stays on continuously and wets fast (high GPM, short radius); a rotor rotates and wets slowly (lower GPM, longer radius). Rotors suit bigger areas and clay soil.
Are MP Rotators worth it? Usually yes for lawns — they cut GPM about in half versus fixed spray, let you run more heads per zone, and reduce runoff. They need clean, filtered water.
Can I mix head types on one zone? Only types with the same precipitation rate. Mixing sprays and rotors on one zone causes uneven watering. Keep bubblers and drip on their own zones.
Which head is best for windy areas? Impact sprinklers handle wind best because of their heavy, low streams; MP Rotators also drift less than fine sprays.
Do bubblers replace drip for trees? They’re interchangeable in function — both target the root zone with low loss. Bubblers are simpler on a sprinkler valve; drip is more flexible for multiple plants.
