A garden sprayer is one of those tools that sounds simple until you realise how much the wrong choice costs you — in time, effort, and aching shoulders. Whether you're tackling weeds on a patio, treating a lawn, or managing a large plot, the right sprayer makes the job feel effortless. Our Lawn & Garden Sprayers collection has options for every scale of garden. Today we're comparing three of the best: the Spear & Jackson 3L Pump Action Sprayer, the Gardena Comfort 5L Pressure Sprayer, and the Faithfull 16L Knapsack Sprayer.
Spear & Jackson 3L Pump Action Pressure Sprayer — The Compact All-Rounder (£35.37)
The Spear & Jackson 3L is the sprayer you reach for when you need something quick, light, and versatile. At just 3 litres it's easy to carry and manoeuvre, making it ideal for spot-treating weeds, applying feed to a small lawn, rinsing down a car or bike, or tackling muddy boots after a walk. The telescopic brass wand and adjustable directional brass nozzle give you precise control, while the transparent indicator window means you always know how much liquid is left.
A few pumps builds the required operating pressure, the automatic safety valve prevents over-pressurisation, and the padded carry strap keeps your hand free for steering the wand. At £35.37 it's the most affordable of the three — and for smaller gardens or occasional use, it's all you need.
Best for: Small gardens, patios, spot treatments, car and bike care, occasional use
Capacity: 3 litres
Key features: Telescopic brass wand, adjustable nozzle, safety valve, padded strap
Price: £35.37

Gardena Comfort 5L Pressure Sprayer — The Precision Garden Tool (£55.63)
Gardena is one of the most trusted names in garden equipment, and the Comfort 5L shows exactly why. It's a step up from the Spear & Jackson in both capacity and refinement — the adjustable nozzle ranges from a focused jet to a fine mist, giving you genuine versatility across different tasks. The practical viewing strip lets you monitor liquid levels without opening the tank, and the ergonomic foot tread provides a stable base for pumping even on uneven ground.
The included nylon filter is a thoughtful touch: it strains home-made brews and natural remedies before they enter the pump, preventing nozzle clogs and keeping the sprayer running smoothly for longer. If you take your garden seriously and want a tool that matches that commitment, the Gardena is the one.
Best for: Medium gardens, precision applications, natural remedies, regular use
Capacity: 5 litres
Key features: Jet-to-mist nozzle, viewing strip, foot tread, nylon filter, shoulder strap
Price: £55.63

Faithfull 16L Knapsack Pressure Sprayer — The Large Plot Workhorse (£71.75)
When you have a large garden, allotment, or paddock to manage, a 3L or 5L sprayer means constant refilling — and that kills your momentum. The Faithfull 16L Knapsack is built for serious coverage. Worn on your back with twin ergonomic shoulder straps and quick-release buckles, it distributes the weight evenly so you can work for extended periods without fatigue. The pump-as-you-go action keeps pressure consistent throughout, and pressure release safety valves ensure safe operation at all times.
The 140cm hose and 90cm lance give you excellent reach, and the three interchangeable nozzles — twin, fan, and four-hole — let you adapt your spray pattern to the task. The shatterproof, frost-resistant tank means it'll survive being left in a cold shed over winter. At £71.75 it's the most capable sprayer of the three by a significant margin.
Best for: Large gardens, allotments, paddocks, intensive or professional use
Capacity: 16 litres
Key features: Twin shoulder straps, 3 nozzles, 140cm hose, pump-as-you-go, frost-resistant tank
Price: £71.75
