Z-GJRE Water Fed Pole Kit, Window and Solar Cleaning Pole w/Water Fed Telescopic Brush/Brush Window and Solar Panel Cleaning System Windows Cleaning & Washing Tool (3.6M-9M)

First off I have not even used this yet and will update my review afterwards to state whether it's effective or not in cleaning solar panels.First you should know that there are no instructions for this item or any of it's variants on Amazon. You are going to have to search for various pictures to figure out how to assemble it. You will also have extra parts (you get two hoses, one long enough and one even longer, some connecters to what I don't know that hook to the small hose they give you, a coupler you will not need unless you want to connect both hoses together which is bad idea because you will get even less pressure and water flow and a shut off valve that can connect to nothing). Put all of this aside but retain the one brass fitting with a 1/2" female pipe end and the other a connector for the small provided hose.Now you will need to get a fitting from somewhere that connects a garden hose to a female 1/2" pipe. 3/4”GHT Male x 1/2”NPT Male Connector. You may end up needing a 1/2" nipple between your garden hose adapter if you can only find or have a 1/2" NPT female adapter like I show in my picture. I also had a shut off valve in 1/2" that took the place of the nipple.Once you have these parts then take one of the provided black hoses and snake it down inside the collapsed tube. You will need to extend the small tube about 4" to find a oval hole the tube gets inserted into. Then push the tube until it gets stuck at the bottom. If you are super lucky it will pop out of the bottom hole but 99.99999% of the time you will have to get something to free it up from the bottom and extract it like needle nose pliers are perhaps just small screw driver.Once you have that end of the hose through the pole you can attach you fitting assembly above to the end. Then pull all but about 18" of the hose left at the top to attach to the brush assembly.From here you will use the 2:1 splitter and 2 4-way splitters along with 8 pieces of provided tubing. See the pictures on how this is arranged. Do the two outer connections from the T's first and then once that is on the brush cut the center or bottom tubes to length. Then join the other side of the two 4-Ways to the 2-Way. And finally the single end of the 2:1 to the hose sticking out of the pole.You are now ready to wash. Good luck.EDIT: I have now used the brush to clean my solar panels. I must say it works very well. The amount of water flowing through the brush, the distribution of the water and the softness all seemed to be the correct amount. There were a few bird droppings that would not come off but that is to be expected. Probably 10-20 minutes of pre soaking in those areas would be best.Overall a very good product minus the missing parts (garden hose adapter and instructions). It would have gotten 5 stars had they provided these.

Brush received is not 40mm wide as described - it is only 34mm.

Though it took a while to get this window cleaner, as it is sourced internationally, the product is exceptional. Though there weren't any assembly instructions, it's pretty easy to figure out.Initially I had put it all together but there wasn't any adapter to plug into my American hose line. I reached out to the vendor and they apologized then came back with a 50% off deal which was great for me as I could then buy the adapter at the hardware store.It works great but you do need to be aware that any extension pole needs exceptional control. Very easy to use and you can't beat the value!p.s. The vendor ended up giving me a full refund and let me keep the product! Crazy, right?! It just shows their commitment to the customer. I wouldn't expect them to do this all the time but I have to say that they have impressed me. Thanks!

Took a bit to put together and attach to hose.

THE UNIT DID NOT COME WITH TO CONNECTORS FOR STANDARD WATER GARDEN HOSE. NO ADAPTATION TO AMERICAN GARDEN HOSE WHATS SO EVER. CUSTOMERS ARE LEFT ON THERE OWN TO COME UP WITH THERE OWN ADATAION SKIM. WOULD NOT RECOMMEND UNIT TO ANYONE YOUR BETTER OFF BUYING AMERICAN MADE PRODUT ON THIS ONE.

This setup works great! Cleaned a total of 47 panels that were filthy within 2 hours. I used this pole in conjunction with a DI filter system. Perfect!

The cost is too high for the product. Does not include instructions. Does not have the correct connectios to the hose.The worst thing I ever bought in amazon
