Game changer

This Hart 20 volt battery operated backpack sprayer is a lifesaver! As a California state-licensed pest control technician, I service anywhere from 10 to 20 accounts on a daily basis. I have pretty bad tennis elbow, so manually pumping my old backpack sprayer was starting to become a problem. I've used the Hart 20v backpack for a few weeks now, and I love it! The battery lasts me through the day. It's ergonomic, and fits great. My favorite feature is to be able to use it as a backpack OR by hand, for those smaller jobs. I take care of my equipment, so I've already taken the Hart 20-volt apart to clean, and that was extremely easy and only took me 10 minutes. This Hart 20-volt battery fits in all their other tools, so it's convenient if you have any other of their products. I definitely recommend this sprayer.

Love, Love, Love

The battery took about an hour to charge and the battery is supposed to be able to disperse 30 gallons before having to charge again. When I got it out of the box all I had to do was screw hose on the bottle and then screw the wand to the hose. The backpack was already on the bottle, so I took it off since I did not plan on using it. Maybe if you have a huge yard this would be perfect for you, but mine is small. I decided to mix Fish Emulsion and fertilize my plants that I have outside. Put in the gallon of water and then added one tablespoon of Fish Emulsion, slid battery on and off I went. Pressed the start button and pointed the Wand at my plants and pressed the button on the wand. Works great. I did have to change the spray to meet my needs, but that was it. Per instructions, you are supposed to clean out after each use and not store in the container. I did this, but if I did not use all my solution, I decided that you could take the motor off the tub which has the tube and therefore only the tub would have formula in it and you could store that way and nothing would be stopped up. Now I am using the backpack to store in after use. I find that I can take the wand off and stick in the backpack for storage. But remember this is battery operated and you should not use in the rain or leave your sprayer in the weather. I am 67, female and have no issues carrying this around.


The chemical sprayer worked wonders for me. I sprayed my weeds in my yard and in my garden. The sprayer has a wide and even spray when used,, no pumping is required at all because of its adjustable sprayer nozzle. The sprayer have its own measuring cup tp measure your chemical to be used in the sprayer. The holster is removeable if you don't want to use it on your shoulders to carry the chemical sprayer, it would be better if you did , it will help better with the spraying.

The battery charger is easy to use, follow the directions for the charger, the battery on the charger will let you know when it is completed. The battery charger is light weight . The chemical sprayer is the BEST and saves a lot of time and gets the job done.

I would recommend this product.


This chemical sprayer backpack is great. Not only holds 2 Gallons but u can also remove the straps if you don't want to use them. It's easy to use. Very convenient.
