Hoover CH90100 .5 gal electrostatic sprayer - rechargeable 20v LI-Ion battery & charger
Country of origin - China
I actually thought I was ordering a paint-sprayer.
This product is NOT intended for paint - only use liquids that are thin as water.
Upon unboxing, I saw a commercial grade (not home-owner) tool - you can tell the difference in weight and fit/finish.
High-grip handle with room for gloved hands (left or right)
Intuitive nozzle swap system with easy key (see pics)
Easy battery re-charge system (I wish Hoover and other battery power systems - Brand-M, Brand-R, for example - could/should be swappable - but aren't)
Testing the machine w/ clear water fill (easy to fill) I had the chance to see the difference between "electrostatic" function and common - see side switch and grounding bracelet in pics.
Personally, I was unable to tell the difference.
It may be different with other spray media.

My review is of the HOOVER Commercial cordless .5 gallon Electrostatic Sprayer. I got this to spray sanitizer mist on surfaces. I had been using a pump type sprayer in the past. This work so much better. The mist is charged and is attracted to the surface so it completely covers the area being treated. The sprayer is also very simple to use. The fluid must be thing as water, as stated in the instructions, when added to the sprayers container. There are 4 changeable nozzles with the sprayer. Changing them is simple, the tool needed is attached to the sprayer, as are all the nozzles. Since the unit is cordless the fully charge battery must be installed prior to use. Just the spray comes on with the trigger. If the electrostatic function is needed then the red rocker switch on the side of the unit must be turned on. The unit is remarkably quiet when in operation. Be sure to remove excess chemical solution from the container after use and flush with some fresh water. This will protect the working parts from damaging chemicals. I am really happy with this sprayer!!
This Hoover electrostatic sprayer did a great job of eliminating the stagnant odors from our 5 dogs, by killing the odor causing germs. The sprayer is very simple & easy to operate. A single start/stop switch is located on the handle for consistent spraying. The sprayer comes complete with 4 replaceable nozzle tips. The nozzle tip sizes range from 40 microns for finest/lowest coverage spray to 160 microns for coarsest/highest coverage spray. I installed the 160 micron nozzle tip with the included nozzle instalation tool. The other 3 nozzle tips are conveniently stored on the nozzle head. I put on wrap around safety glasses, breathing mask, long sleeve work shirt & hat. I filled the tank, located in the rear, with 1/2 gallon of disinfectant. A switch, located on the side of the unit, is used to select whether the spray is electrostatically charged, or not. I turned the switch "ON", for the electrostatic spray mode. I put the elastic electrostatic band on my wrist, making sure it was adjusted securely so the band makes continues contact with my skin. I made sure no one was in the house & the windows were open for ventilation. I used long overlapping strokes to spread the spray. I came back into the house, after an hour of drying time. The stagnant odors were gone! The sprayer also includes an easy to read & understand user manual with lots of graphics, adjustable shoulder strap, battery charger & removeable 20-volt, 4.0 Amp Hour Lithium-Ion battery. The battery has 4 lights that show how much power is left in it, when the battery button is pushed. After I sprayed a 2,000 sq. ft. area, the battery still had plenty of power left. This is a heavy duty, durable, great sprayer!

This review is for HOOVER Commercial Cordless 1/2 Gal. Electrostatic Sprayer. I love my new electrostatic sprayer. It has excellent coverage. The 1/2 GAL. capacity is just right. It holds enough solution to get the job done without tiring my arm out. It comes with 4 Interchangeable nozzles, sizing from 40 to 160 microns. I tried all four of them and they all work great. The battery is powerful enough to get the job done in one charge. I would highly recommend.

The Hoover Commercial Cordless ½ Gallon Electrostatic Sprayer is an extremely timely tool. Concerns about possible contagion create the need to clean those items which may come into contact with multiple people on a frequent basis. This battery-operated tool is portable and easy to use, and comes fully equipped with a 20V lithium ion battery, wall charger, four different spray nozzles, a tool which facilitates the quick and easy insertion or removal of each nozzle, a grounding strap, and storage on the sprayer itself for each of the nozzles, to prevent their becoming lost. It has an easy-to-fill fluid reservoir which can hold a half-gallon of spray solution. Overall, very well designed and easy to use, even for a complete beginner.

This commercial electrostatic sprayer and be used commercially and for at home use. It comes with a 4.0 20v battery and charger, with the cordless capability you can take this sprayer anywhere. I used it in our home and we sprayed all the bathrooms, kitchen and entry way to our home it’s very easy to use. I was able to purchase a recommended disinfectant liquid and just added it to the tank. It comes with 4 interchangeable nozzle sizes from 40 to 160 microns allow for the flexibility of multiple spray patterns and this is great when you have a large area to cover. The sprayer worked very well and I would recommend it to anyone looking for an electrostatic sprayer.

The "HOOVER COMMERCIAL CORDLESS 1/2 GAL. ELECTROSTATIC SPRAYER", is an excellent product. Sturdily built with quality materials. Its design and performance is what prompt me to purchase one.
This is also a well balanced tool, easy to operate, easy to clean and easy to store.
A complete set of instructions is provided with the sprayer, which for your safety and, proper use I, recommend reading.

I really really like this electrostatic sprayer. It works perfectly and helped me to sanitize my front stoop and sitting bench. Very easy to use as long as you read the directions. It comes with 4 nozzle pieces that change the intensity of the spray. It also comes with a tool to make changing out the nozzles easier. I would recommend some type of clamping tool to actually hold the nozzles in place while you're installing them. Filling the tank with a water-based sanitizer can make the electrostatic sprayer heavy, but the company has already thought of that and provided a shoulder strap. I recommend using the medium or low setting nozzles as the high setting seems to be a bit much. Great design and really easy to use.

A very nice, heavy duty feeling electrostatic sprayer.
We can't be too careful about germs and this new cordless sprayer by Hoover makes it way easier to keep the home, cars, and shop clean and as germ free as possible.
This includes everything you need aside from the actual liquid spray.
4 AH 20V battery, charger, the sprayer itself and a shoulder strap.
4 (FOUR) spray nozzles of different size are included and color coded, all store on the machine itself and they can be removed by hand, no tools needed.
Simply fill the hopper with 1/2 gallon of your spray of choice and get to work. Put the static bracelet on your wrist (to keep you from getting covered in spray).
That's it. Fill, pull the power trigger and spray.
It creates a nice thin mist that clings to everything it's sprayed towards.
It's very quiet as it runs.
The coverage is thin and even. Just enough to do the job but not hose the surface down and leave it feeling soaked.
I did the entire first floor of the house (1200 sq ft) and still had charge left in the battery. I'm not sure exactly how long the pack lasts, but I could easily do my entire home (2100 sq ft) and maybe even the cars on one battery pack.
Easy to use, all in one package, recommended!

Love the electrostatic option when spraying so that the product you spray "sticks" to the object with a super fine coating and enables the product to go farther and not be wasted unnecessarily. There are four different sized tips for it, and each may be easily cleaned, The battery operation allows it to operate anywhere. So you can disinfect anywhere at any time with the proper viscosity. One thing in particular that I like is its multipurpose usage, and in the garden with the fogging capabilities as well as the electrostatic capabilities it is very easy to coat all the leaves, on both sides which also makes the product stretch out for more applications per gallon. The Tank holds one gallon of liquid with H2O consistency which is the amount I use the most often. It is quiet and non offensive/
