This sprayer has the similar to Windex bottle - it can be used on thin coils.
It wets and coats the coils with soap as it's not nearly powerful enough to force its way through the coil.
It has been couple of weeks since I wrote the first part of this review.
I decided to come back and lower from two stars to one star.
I just could not believe that manufacturer of product would be so stupid as to put such product out there that has to have certain amount of pressure and just make it at so low pressure.
The reason that PSI is so low is that they use small $35 motor used in under the sink reverse osmosis purification system.
Those motor have to be very PSI otherwise it will damage the reverse osmosis membrane.
Their little 12v motor will pump 1.4 gallons of water per minute.
For machine like this to work, they need motor that will pump at least 4 gallons of water per minute.
I have another little 12v motor that I bought via Amazon that I paid $17 and it pumps 5.3 gallons per minute.
