Best OverallPros

- Consistent pressure without pumping
- Durable build with good warranty
Cons
- Heavier than manual models
- Battery not replaceable by user
The Hozelock 20L Battery Sprayer is a workhorse for medium to large gardens. Its 12V battery delivers a steady 45 PSI, allowing you to cover large areas without manual pumping. Owner reviews consistently praise its reliability and the even spray pattern from the adjustable lance.
The 20L tank means fewer refills, and the shoulder strap makes carrying it manageable. While it is heavier than smaller manual sprayers, the convenience of battery power and the build quality justify the weight. It is the best garden sprayer under £100 for anyone with a substantial garden.
Ryobi 18V ONE+ 5L Sprayer
Best Budget BatteryPros
- Uses Ryobi ONE+ battery system
- High 60 PSI pressure
- Lightweight and compact
Cons
- Small 5L tank
- Battery and charger sold separately
The Ryobi 18V ONE+ 5L Sprayer is an excellent choice if you already own Ryobi tools. It delivers a powerful 60 PSI, which is higher than many competitors, making it great for spot treatments and reaching tall plants. The trigger handle is comfortable and allows for precise control.
Its 5L capacity is best for smaller gardens or targeted tasks. The build quality is solid, and the ability to use existing Ryobi batteries is a major cost saving. It is a top contender for the best garden sprayer under £100 for users invested in the ONE+ ecosystem.
Bosch Universal 5L Garden Sprayer
Best Manual PrecisionPros
- Ergonomic pump handle
- Transparent tank for level visibility
- Bosch reliability and warranty
Cons
- Requires manual pumping
- Plastic lance feels basic
The Bosch Universal 5L Garden Sprayer is a well-built manual sprayer that offers excellent control and precision. The pump handle is comfortable to use, and the 45 PSI maximum pressure is sufficient for most garden tasks. Owners appreciate the clear tank that shows the liquid level at a glance.
It is ideal for applying fertilisers, weed killers, and pesticides to flower beds and vegetable patches. The spray pattern is adjustable from a fine mist to a direct jet. For those who prefer a simple, reliable manual sprayer without batteries, this is a strong choice.
Karcher 2-in-1 5L Garden Sprayer
Best VersatilityPros
- 2-in-1 spray and water wand
- Lightweight and easy to carry
- Good for watering and spraying
Cons
- Lower PSI than dedicated sprayers
- Plastic fittings feel less durable
The Karcher 2-in-1 5L Garden Sprayer stands out for its dual functionality. It works as both a pressure sprayer for chemicals and a gentle water wand for watering plants. The switch between modes is simple, making it a versatile tool for gardeners who want one device for multiple tasks.
Owner reviews highlight its convenience for smaller gardens and patio plants. The 30 PSI is lower than other manual sprayers, so it is not ideal for heavy-duty weed killing or reaching high branches. However, for general garden maintenance and watering, it is a practical and affordable option.
Draper 5L Pressure Garden Sprayer
Best Heavy Duty ManualPros
- High 60 PSI for tough jobs
- Durable polyethylene tank
- Excellent value for money
Cons
- Pump handle can be stiff
- No pressure relief valve
The Draper 5L Pressure Garden Sprayer is a no-frills manual sprayer that delivers impressive 60 PSI pressure. It is built with a tough polyethylene tank that can withstand chemicals and rough handling. This makes it a great choice for heavy-duty tasks like applying strong weed killers or treating large areas.
Owner reviews note that it provides a strong, consistent spray that can reach higher plants. The main drawbacks are the stiff pump action and the lack of a pressure relief valve, but for the price, it offers outstanding performance. It is a reliable budget option for demanding garden work.
What to check before buying a garden sprayer
Choosing the best garden sprayer under £100 depends on your specific needs. The most important factor is the type of spraying you do. For large lawns and borders, a battery-powered sprayer with a large capacity saves time and effort. For precise spot treatments on flower beds, a manual sprayer offers better control and is lighter.
Consider the pressure (PSI). Higher PSI means better reach and atomisation, which is crucial for herbicides and pesticides. Tank material matters too: polyethylene is durable and chemical resistant. Also check the warranty and brand reputation. Hozelock, Ryobi, Bosch, Karcher, and Draper all offer reliable products with good support.
Mistakes to avoid
A common mistake is buying a sprayer with too small a capacity for the garden size. A 5L sprayer is fine for patios and small borders, but for a large lawn, a 20L model like the Hozelock is far more practical. Another error is ignoring the pressure rating. Low PSI sprayers struggle to reach tall plants or create a fine mist for even coverage.
Many users also overlook the importance of build quality. Cheap plastic sprayers can crack or leak after a season. Stick to reputable brands and check owner reviews for long-term reliability. Finally, do not forget to consider the battery system. If you buy a battery sprayer, ensure the battery is readily available and compatible with other tools you may own.
