I have and use all the systems in the US market. I use them on all indoor window cleaning jobs. I like the Stingray with deep cleaning pad best but for windows above 2 floors I like the Cleano better. The poles are stronger. We use the bronze wool 6by9 pad on all windows that have a heavy film first then use the green pad or gray pad and even the white and green pad. To answer your other questions I and posting a link to both of these products. https://windowcleaner.com/unger-stingray-indoor-quickstart-cleaning-kit-5-foot
Like any tool there is a learning curve but I have been working with it since day one when it hit the market with the Unger Speed Clean Kit
For a seasoned window cleaner who has mastered a pole yes. But you risk drips inside and that can be costly. A new window cleaner can master a indoor wfp in a few days and there is no drip.
Do you find the stingray pads start smearing real quick due to the dirt build up on the pad. I went back to trad for interior work but I’m thinking about giving the stingray another go.
Try the deep cleaning pad. It holds more dirt and last longer. The key is to not over wet the pad because the water takes up the space that traps the dirt. Also over wetting causes the smearing and also washing the pads in detergent causes smearing. Just use hot water and 2 rinse cycle.
I am going to be trying out an Interior WFP system called the Dragonfly that is from the UK. The version I purchased is the sprayer head that I can mount on my regular carbon fiber pole with a hose that runs down and connects to a water bladder (which you fill off of your pure water system) and battery powered pump that are mounted in a backpack similar to a Camelbak. There is a remote on a lanyard that the operator controls the re-wetting of the pad at the end of the pole.
I originally looked at the Cleano, but it is limited to the length/height be it’s own design. And I read several negative reviews of the Stingray.
I have to clean the interior and exterior of a local car dealership this weekend during the overnight hours, so this will be the test. 275 pieces of glass on the interior and 370 pieces on the outside.
So the cleaning only went okay. I had some issues with the connections and tubing set up between the US 5/16th and the UK 4mm and 6mm. There were also significant issues with the amount of dirt/residue on the inside of the windows. The building is 10 years old and they have only had the windows cleaned twice in that time period. They are constantly driving vehicles in and out of the showroom, and while I know it is only trace amounts of exhaust in the air, it still builds up over the years. I went through 4 of the heavy scrubbing pads with only getting to about 80 windows. I then had to go back over the same windows with a polish pad to remove the “haze” left behind. Finally the bottom 8ft I cleaned traditionally only because I wanted to get the clearest view for the clients and I had run out of clean polishing pads. I did inform them that they need to have a regular monthly cleaning in order for me to get the windows to a perfect clarity state and then maintain them. It is going to take multiple cleanings to get the glass properly cleaned while using this method, but they are a LEED platinum facility so any reduction in chemical usage helps them maintain their status from what they tell me.
RHG carried that product at one time and we sold several. It’s a nice system and easy to use. Next time you do a first clean add 50/50 rubbing alcohol and also bronze wool first
