Flymo 8L Pressure Sprayer
Best OverallPros
- Comfortable pump handle with good leverage
- Transparent tank for easy liquid level viewing
- Durable HDPE construction resists chemicals
Cons
- Pressure gauge not included
- Seal can dry out if stored with liquid inside
The Flymo 8L Pressure Sprayer is the sweet spot in the range. It holds enough liquid to treat a medium-sized lawn or a row of flower beds without needing constant refills. The pump action is smooth, and the adjustable brass nozzle provides a fine mist to a strong jet, making it versatile for feeding plants or applying weed killer.
Owner reviews consistently praise its reliability over several seasons. The main complaint is the lack of a pressure gauge, meaning you have to judge pressure by feel. However, the safety valve works well to prevent over-pressurisation. For the average gardener, this is a dependable workhorse.
Flymo 5L Pressure Sprayer
Best for Patios & Spot TreatmentsPros
- Lightweight and easy to carry
- Ideal size for precise application
- Good build quality with leak-proof cap
Cons
- Small capacity requires refills for larger areas
- Pump handle can feel a bit short
The 5L version is the perfect companion for patio weed control and treating specific plants. It is much lighter than the 8L model, which makes a difference when you are carrying it around for extended periods. The adjustable nozzle works well, and the trigger lock is handy for continuous spraying.
Some users note the pump handle could be longer for better leverage, but it still builds pressure effectively. The smaller tank means less chemical waste if you only need a small amount. It is a solid choice for those who prioritise portability over capacity.
Flymo 12L Knapsack Sprayer
Best for Large Gardens & LawnsPros
- Higher 4 Bar pressure for better reach
- Comfortable padded shoulder straps
- Large capacity reduces refill stops
Cons
- Heavier when full, can be tiring
- Pump mechanism can be stiff initially
For larger gardens, the Flymo 12L Knapsack Sprayer is a significant upgrade. The 4 Bar pressure provides a stronger, more consistent spray that can reach the back of tall shrubs or cover a lawn quickly. The padded straps distribute the weight reasonably well, though a full tank is still heavy.
Owners appreciate the longer wand that comes with the knapsack, which reduces bending. The higher pressure also helps with atomising chemicals for better coverage. The main downsides are the weight and the initial stiffness of the pump, which loosens up over time. It is a capable tool for serious gardeners.
Flymo 1.5L Hand Sprayer
Best for Houseplants & Small PotsPros
- Very small and easy to store
- Good for precise misting of leaves
- No pumping required
Cons
- Trigger can be tiring for prolonged use
- Not suitable for large areas
The Flymo 1.5L Hand Sprayer is a simple trigger-operated bottle. It is ideal for watering houseplants, applying foliar feeds, or spot-treating a few weeds on a patio. The adjustable nozzle allows you to switch from a jet to a mist, which is gentle on delicate leaves.
It is not designed for heavy-duty work. The trigger mechanism can cause hand fatigue if used for more than a few minutes. However, for its intended purpose, it is a cheap and effective tool. It is best seen as a supplement to a larger pressure sprayer.
What to Check Before Buying a Flymo Garden Sprayer
Before you buy, consider the size of your garden. A 5L sprayer is fine for a patio and a few flower beds, but an 8L or 12L model is better for lawns and large borders. Also check the pressure rating. Higher Bar means better reach and atomisation for chemicals.
Look at the nozzle type. Adjustable brass nozzles are more durable than plastic ones. For knapsack models, check the strap padding and the length of the spray wand. A longer wand reduces back strain. Finally, consider the warranty. Flymo offers a 2-year warranty, which is standard for this price range.
Mistakes to Avoid When Using a Flymo Sprayer
A common mistake is leaving liquid in the tank after use. This can cause seals to swell or degrade. Always empty and rinse the sprayer with clean water after each use. Another error is over-pressurising the tank. Pump only until you feel resistance; the safety valve is a backup, not a guide.
Do not use the wrong nozzle setting for the job. A fine mist is good for foliage, but a jet stream is better for soil drenching or weed roots. Also, avoid mixing chemicals directly in the tank. Mix them in a separate container first to ensure proper dilution and prevent clogs.
Who Are Flymo Garden Sprayers For?
Flymo garden sprayers are designed for domestic users. They are not professional-grade tools, but they are reliable for regular home garden tasks. They suit gardeners who want a simple, no-fuss tool without complex features like battery-powered pumps or digital controls.
If you have a large garden or a smallholding, you might need a more robust brand like Stihl or a battery-powered option from Ryobi. However, for the typical suburban garden, a Flymo pressure sprayer offers excellent value and dependable performance.
Performance and Build Quality
The performance of Flymo sprayers is consistent. The pump mechanisms are smooth and build pressure quickly. The 3 Bar models are adequate for most tasks, while the 4 Bar knapsack offers noticeably better reach. The spray pattern from the adjustable nozzles is even and reliable.
Build quality is good for the price. The HDPE plastic is resistant to chemicals and impact. The seals and O-rings are the main weak points, but they are standard and easily replaceable. Overall, Flymo sprayers are built to last several seasons with proper maintenance.
Alternatives to Flymo Garden Sprayers
If you want a battery-powered sprayer, the Ryobi 18V ONE+ Sprayer is a popular cordless option. For a more heavy-duty knapsack, Stihl SG 20 is a professional choice. For budget-conscious buyers, the Hozelock range offers similar quality and a wider variety of models.
Another alternative is the Karcher battery sprayer, which integrates well with their pressure washer ecosystem. Each brand has its strengths, but Flymo remains a strong contender for simple, manual spraying at a fair price.
