Flymo vs Stihl Pressure Sprayer
Choosing between a Flymo and a Stihl pressure sprayer means comparing two very different brands: one known for affordable garden maintenance and the other for professional-grade outdoor power equipment. This guide breaks down the key differences in power, build quality, and battery ecosystems to help you pick the right sprayer for your garden.
Quick answer
For most homeowners, the Stihl SG 51 is the top pick due to its superior build quality, higher pressure output, and reliable dealer network. The Flymo Contour 900E is a solid budget-friendly alternative for light, occasional spraying tasks, but it lacks the durability and power of the Stihl.

Flymo vs Stihl Pressure Sprayer: Which One Should You Buy?
When you need to apply weed killer, fertiliser, or pest control, a pressure sprayer saves time and effort compared to a watering can. Flymo and Stihl offer two very different approaches. The Flymo Contour 900E is an entry-level electric sprayer aimed at the casual gardener. The Stihl SG 51 is a battery-powered model built for users who demand reliability, higher pressure, and the flexibility of a cordless tool. This comparison looks at pressure output, battery compatibility, build quality, and real-world owner feedback to help you decide.
What to Check Before Buying a Pressure Sprayer
Before choosing between these two models, consider these key factors. Pressure (PSI) determines how far and how finely the liquid is sprayed. Higher PSI is better for reaching tall plants or covering large areas quickly. Tank capacity affects how often you need to refill. Battery compatibility is crucial if you already own tools from a brand's ecosystem. Build quality and warranty length indicate how long the sprayer will last under regular use. Finally, check the type of nozzle: adjustable nozzles offer more versatility for different tasks.
Mistakes to Avoid When Buying a Pressure Sprayer
A common mistake is buying a sprayer with too low pressure for your tasks. A 150 PSI unit like the Flymo works for small flower beds but struggles with tall shrubs or large lawns. Another error is ignoring the battery ecosystem. If you already have Stihl batteries, the SG 51 is a no-brainer. If not, you need to factor in the cost of a battery and charger. Many users also overlook the importance of a good hose and wand length. A short wand makes it difficult to spray under leaves or reach the top of plants.
Flymo Contour 900E Pressure Sprayer Review
The Flymo Contour 900E is a budget-friendly electric sprayer designed for the casual gardener. It is corded, meaning you are limited by the length of your extension lead, but it offers consistent power without worrying about battery life. The 1.3-gallon tank is adequate for small to medium gardens. Owner reviews on retailer sites highlight its ease of use and low price point, but many note that the plastic components feel less durable over time. The pressure is fixed at a moderate level, which is fine for general spraying but not for high-reach tasks.
Flymo Contour 900E
Best Budget PickPros
- Very affordable price
- Lightweight and easy to carry
- Simple to operate with no battery to charge
Cons
- Limited to cord length
- Lower pressure output
- Plastic build feels less durable
The Flymo Contour 900E is a straightforward, no-frills sprayer. It plugs into a standard outlet and delivers a steady stream of liquid. The 1.3-gallon tank is transparent, making it easy to see the liquid level. The wand is short, which is fine for ground-level spraying but less effective for overhead tasks. Owner reviews on Amazon and other retailers consistently mention that it is good for the price but not built for heavy use. Several users reported the pump failing after a season of regular use.
For a casual gardener with a small yard and access to an outdoor power point, this sprayer works well. It is ideal for applying weed killer to a patio or fertiliser to a few flower beds. However, if you have a larger garden or need to spray trees and tall shrubs, the lower pressure and cord limitation become frustrating. The Flymo is a decent entry-level tool, but it is not a long-term investment.
Stihl SG 51 Pressure Sprayer Review
The Stihl SG 51 is a battery-powered sprayer that offers significantly more pressure and build quality than the Flymo. It is part of the Stihl AK battery system, meaning it shares batteries with other Stihl garden tools like trimmers and blowers. The sprayer features a robust pump that can reach up to 300 PSI, allowing for a longer reach and finer mist. The tank is the same 1.3-gallon capacity as the Flymo, but the materials feel much more premium. Owner reviews consistently praise its reliability, ease of starting, and the quality of the spray pattern.
Stihl SG 51
Best Overall / Professional GradePros
- High pressure for long reach
- Durable, professional build quality
- Shares batteries with Stihl AK tools
Cons
- Higher price point
- Battery and charger sold separately
- Heavier than corded models
The Stihl SG 51 is a significant step up in performance. Its 300 PSI pump produces a powerful, adjustable spray that can easily reach the top of a 10-foot shrub or cover a large lawn quickly. The wand is longer than the Flymo's, improving ergonomics and reach. The trigger lock mechanism is well-designed, reducing hand fatigue during extended use. On retailer sites like Amazon and Stihl dealers, owners frequently mention that the sprayer feels solid and well-balanced. Many report using it for several seasons without any issues.
The main drawback is the price. The SG 51 costs more than the Flymo, and if you do not already own Stihl AK batteries, you need to buy a battery and charger, which adds to the total cost. However, for users who already have Stihl tools, this sprayer integrates seamlessly. It is also worth noting that the battery life is good. On a full charge with a standard AK battery, you can spray for about 30-40 minutes of continuous use, which is enough for most residential tasks.
Key Differences: Flymo vs Stihl Pressure Sprayer
The most critical difference is pressure output. The Stihl SG 51 delivers double the PSI of the Flymo, which translates to a longer reach and better atomisation of liquids. The Flymo is corded, tethering you to a power source, while the Stihl is cordless, offering freedom of movement around the garden. Build quality is another major factor. The Stihl uses reinforced polymers and has a reputation for lasting years, whereas the Flymo is built to a lower price point with more plastic components. Finally, the Stihl is part of a larger battery ecosystem, which is a significant advantage if you already own or plan to buy other Stihl tools.
Which One is Better for Your Garden?
If you have a small garden with a few flower beds and a patio, and you are on a tight budget, the Flymo Contour 900E will get the job done. It is simple, lightweight, and cheap. However, if you have a medium to large garden, tall plants, or trees, or if you plan to use the sprayer frequently, the Stihl SG 51 is the better choice. Its higher pressure, cordless convenience, and superior build quality make it a tool that will last for many years. The Stihl also holds its value better if you ever decide to sell it.
Alternatives to Consider
If neither the Flymo nor the Stihl seems right, consider the Karcher P5S battery sprayer. It offers a good balance of price and performance, with a 1.3-gallon tank and adjustable pressure. Another option is the traditional manual pump sprayer from brands like Hozelock, which are very affordable and require no electricity or batteries, though they lack the convenience of power spraying. For very large properties, a backpack sprayer from Solo or Birchmeier might be more suitable, as they offer larger tanks and more comfortable carrying systems.

Our verdict
For most users, the Stihl SG 51 is the best overall pressure sprayer, offering superior pressure, build quality, and cordless convenience that justifies its higher price. The Flymo Contour 900E remains a viable budget option for light, occasional use in small gardens, but it cannot match the Stihl's performance or longevity.
