2. Solo 417 Comfort 18 Litre Electric Backpack Garden Sprayer

BEST PROFESSIONAL PICK

Buy on Mowers-online.co.uk

Solo 416LI Pro 20 Litre Battery Powered Back Pack Sprayer

This Solo 417 Comfort Garden Sprayer runs on a 12V 7.2 Ah battery that powers a built-in pump that can support a maximum water pressure of 62.4psi on setting 2 or 35.7psi on setting 1 for when a lower pressure is needed.

This garden sprayer is designed to handle both outdoor and indoor jobs well. For those with greenhouses, conservatories or kitchen gardens, this sprayer will deliver impressive work and ensure the areas are treated evenly. The battery is rechargeable and it’s supplied with the sprayer and it only takes a few hours to charge.

The garden sprayer comes with a 50cm wand/lance that is adjustable depending on the area you want to cover. The lance comes with a standard nozzle that is able to deliver a spray volume of 1.42l/min or 1.07l/min. It features two variable speeds that will determine the spray volume released from the wand (which we have mentioned previously), this is what controls the spray volume.

This model also comes with an 18-litre plastic tank that has been treated to withstand UV rays. This tank can be used with most chemicals without reacting to the contents. The tank has a large capacity so that the user can cover a considerable area before requiring a refill. In addition, the tank has a gauge that you can look at to determine the remaining liquid and if you need to refill it soon.

For convenience, the garden sprayer possesses a long 150cm hose for easy reach around the garden. It weighs 7.6kgs whilst empty and that is why the backpack feature is important. The handles are comfortable and they are wide enough to prevent the weight of the sprayer from digging into your shoulders, it also has a nice padded back support.

Generally, it is a quality sprayer with a large capacity tank that would suit medium-large sized gardens. It has a 2-year domestic warranty, we feel that this is a little disappointing as you may not be covered if using it in a professional setting and let’s be honest, this will be the majority of people who have purchased this sprayer.

Our recommendation

The Solo 417 Comfort Garden Sprayer is a great choice if you have a large area to work with. The sprayer is designed to handle heavyweight tasks and it has a fairly large tank, making it ideal for professional use too. We appreciate that the battery delivers a decent running time of 2.3-3.7 hours depending on the speed you are operating with, which is perfect for nurseries, garden centres or anyone with a lot of spraying to do.

Additionally, it operates quietly causing no disturbances to the surrounding environment or neighbours who are close by. All in all, it would be suited for those looking for a large capacity garden sprayer that is powerful and comfortable to use and wants to upgrade from the manual pump models.

Our recommendation

Designed for professionals to be used in many situations, from spraying weeds on industrial car parks to pesticides and fungicides on large beds and borders. Also suitable for other spraying applications. A top quality sprayer that comes with 2 years warranty is fantastic because most sprayers only come with 12 months warranty.

So what makes a good garden sprayer?

With lots of choices available in garden centres and online shops, it is hard to know which are the good quality sprayers and which simply don’t make the cut. So what do you need to consider when buying a garden sprayer? That it is made from quality materials including good rubber seals that won’t perish as this will result in low pressure and poor performance. Has it been made from strong plastic that can handle lots of use and won’t crack when accidentally dropped? Is it fitted with brass fittings that have been made to last? Does it have different spray settings? And finally, is it easy to clean?

What to use them for and the different sizes available

Garden sprayers are commonly used for spraying pesticides, fungicides and weedkillers that can be purchased as concentrates which you dilute with water as it is far more cost-effective than using ready-to-use products. There are many sizes of garden sprayers available, from small 2-litre hand sprayers (which are ideal for spraying a small plant or weeds) to medium-sized sprayers that usually around 8 litres for spraying larger areas to even bigger backpack sprayers that can hold 20 litres for spraying even larger areas, these are usually used for spraying large lawns or spraying weedkiller on industrial sites.


Final Conclusion

All the garden sprayers above are of good quality and offer good value for money, in general, you get what you pay for, and the more you pay the better a product you will get.

If you are an amateur gardener looking for a quality garden sprayer to use a few times a year, then one of the cheaper sprayers would be ideal and should offer you years of use if it is looked after correctly and cleaned after each use.

If you are a professional gardener or looking for a very high-quality garden sprayer to use extensively, then we highly recommend investing in a high quality branded model such as those built by Hozelock or Greenkey.

Their products are above the best in the industry and you will never be disappointed with them.

BEST PICK

Our top tips for using a pressure sprayer

1. We recommend never using the same sprayer for spraying both weedkillers and pesticides or any other liquids sprayed on plants. There have been many cases where gardeners have failed to properly clean out sprayers they have previously used to spray weedkillers. They then go on to spray their plants with pesticides or fungicides only to find they have killed their plants. We would recommend having a second sprayer to spray weedkillers.

2. Always ensure all nuts and pipes are tight before use.

3. Only mix the amount you require to spray that day, many weedkillers and pesticides become less effective when left in sprayers over time.

4. Always mix the recommended dose as shown in the instructions.

5. Chemicals are dangerous and care should be taken, including wearing protective gloves when mixing.
