Yofidra Garden Sprayer 20L, Battery Powered Knapsack Sprayer with 2 × 2.0Ah Batteries, 5 Nozzles & 40″ Telescopic Wand, Upgrade Electric Weed Spray & Water Spray For Garden & Lawn

What's surprised me the most about this product is how much liquid it can take. I wanted to treat both my front and back garden with a mild solution of mould killer and hadn't been looking forward to the task. Both the back and front have block paving and there's also rendering on the garden walls too. When this came up I thought it would be perfect for the distribution of the chemicals and speed up the job. Also it can be used come summer with feeding plants (obviously after a good clean). Upon opening I was blown away by the actual size of the product. I have a similar smaller one but this must take at least four times the amount of water. Everything upon opening is held inside the tank - so don't panic when opening, it's all in there, you just need to fish it out. There's five nozzle attachments, one extra is already on the tip of the wand and these provide various levels of ability to hit areas - they work quite well and have actually have assisted massively and especially with hard to reach areas. The wand itself is extendable and can help hit both heights and hard to reach places, it's great for getting into nooks and crannies too. I found it somewhat difficult to understand at first. The instructions are very difficult to understand, there's a chart which shows each part but I can hardly see it. You need the equivalent of a telescope to read both the writing and images. In the end I played it by ear and sussed it out but the instructions could be better as I couldn't comprehend what was jotted on the paper. The connection for the main wand is a flexible pipe and this is reliant on how tight you screw the connector. There are two rubber gaskets but I haven't got a clue where they go, I've tired them before the heads and also before fitting the hose but it prevents them from sealing. As such I've not used them and I'm hoping they're not important. You have two 2.0amp batteries included and the charger, I found these to be excellent and they even fit other tools I have. Charging takes around two hours but I found the batteries lasted no issue and allowed me to complete the task at hand. What I really like is the ability to mix the liquid up. On the unit itself there's two switches, one can be used to swirl the water and the other is the power on switch. The swirling is particularly good for when using with feeder for plants as this will help evenly churn down before applications. You can also keep this on while using and this helps with evenly distributing chemicals too. You can also control the power output and pressure to the unit by turning a dial, I found the position relatively easy to access when wearing and actually fine for getting levels I wanted but the dial is minute. It's literally the size of a nail head and can be awkward to grab. I found the straps comfortable but very difficult to get on. They kept coming loose for example and it took me a good half an hour to set the positioning up correctly and then I did struggle getting both on. They do help with weight distribution though and I found it comfortable to wear. Cleaning wise I was quite happy, it allowed me to get all the areas around the garden with green mould and has reduced what would take a day to an hour. I'm looking forward to using this come summer time and highly recommend. It's just the instructions lacking and difficulty with the straps that have meant I'm knocking one star off.

The thank seems to be good for the mixing and spraying feature however its leaked out the lid and all down my back for every tank I used , only used yesterday ..... follow on review. Also leaks between the seales where the top of tanks groovs are .hopefully i can fix it with some glue

Cost effective garden or automotive sprayer for a number of uses. I ordered it to spray pre wash on my vehicles and will also use it for weedkiller too. Takes a little setting up including back pack straps and spray gun / hose. But once set up it is really easy to operate and has some great features including two batteries, variable pump speed, agitation stirrer and extending lance. I am sp impressed with it and is a valuable addition to my car cleaning procedure.
