q: How high can the mist reach when I stand on the ground? Can I spray 30 seconds for cleaning the roof?
a: You can use 30 Seconds for this, however you would need to clean out the blower thoroughly with water afterward to prevent swollen seals. The radius is approx 3.5-3m, but take a bit off for spraying up in the air. We would recommend getting up on the roof to do a proper job.

q: Would this also be able to do the same job as a backpack leaf blower - when its not needed for misting?
a: No it's quite different, the airspeed is not comparable.

q: Can the mist blower container be rinsed adequately after using weedkiller and gorse killer to then use it for pyretheium bug killers that will be sprayed onto fruit trees?

q: I have a walnut tree over about 8 metres high. It gets insects ants etc and a lot of the nuts get black spots also gets bumpy lumps on its new leaves each spring. I wondered if this sprayer would be good to use with concoquer oil after leaf drop, and early spring, and would it reach the top of the tree.
a: Yes this will be ideal.

q: Can it be used inside for prevention of bugs?

mist blower

Good value for money. Did a mean job of what I bought it for and did it in 1/4 of time. Starting instructions a bit vague but worked out how to start hot and cold with a bit of perseverance. You would be a fool to pay $1100 plus for other blowers without buying one of these first

Awesome unit

Brought this for spraying fungicides and foliar feeds in my greenhouse (925m2) and it's been great! More than halved my spraying times and far more effective coverage etc vs my backpack sprayer. Motor has been spot on so far starts easily and reliably.

Unbeatable value for money. I've done about 90 hours of blackberry spraying with it. It is now starting to blow fuel back through the carb suggesting piston or rings need replacing but doubt whether parts will be available. Secondly - when you get it, go on trade me and for $20 I bought an aluminium framed child's back pack with waist belt and proper wide shoulder straps - after pulling the back pack apart I fitted the blower to it and it works perfectly - if you don't do something with the straps the chances are you wont use it long before swearing and cursing!

Good product

Does everything I expected. A trifle heavy with a full load of mix on board for an older fellow but manageable if it is high enough when I put it on.

Backpack operates as it should. Easy start, I am still finding out the best settings for me. Instructions for assembly are very vague. The pictures in the book are also vague.

Blown away

As always with equipment its about buying the right piece of gear for your job. This blower is a quarter of the price of the big brand machine but I'm not about to spend big on something that's only going to do 3 - 4 hours a year. This one is priced right, its doing the job perfectly, and the quality looks good. Great spares kit. Would've got 5 stars but the assembly and operating instructions were a bit of a challenge.

CAUTION - poor quality harness

over 2 years ago


Quite possibly the worst piece of garden equipment I have ever purchased. When I went to secure the unit to my back the chest cross piece stitching tore, then the shoulder strap adjusters keep slipping through the buckles. The unit has fallen off twice within 20 minutes of starting to use it and is now relegated to the junk heap never to be used again - back to hand spraying in the orchard.

Very recently purchased one off these, wasn't to difficult to get it up and running, compared to the more expensive models of these it is excellent value, you can get 6 of these for the price of the others, its all i need for the trees Ive got. Excellent trader supplied within 24hrs. Tks.

Value for money

I'd been looking at one of these for a while, and there were a couple of very good reviews, so bit the bullet. I have a few fruit trees which need plenty of maintenance, especially over the warm/wet months. I needed something which would get into the middle of the trees from below with both insecticide and fungicide. The first time I used it, there were clouds of whitefly, mission accomplished. One of the easiest machines to start, I find the straps a little annoying in the way they are designed, especially around the throttle, but I'm very happy with the performance.

Sprays well but had a major problem with the straps. They just fall off. We lost time and have had to tie knots in them and tape them. They were too long and hung to low on the back and you run out of adjustment. It is value for money.

Great value product

Firstly the delivery was quick and well wrapped. Assembly was relatively easy but a better assembly desciption would be nice. In use the sprayer worked very well. It is a little heavy for an old, but average for the type of sprayer. We're impressed.
