Frequently Asked Questions
Q: How many different SkyPro products are there?
A: There are 15 different models with a variety of options that can be added to the basic models. All of these different models either fall into the brush SkyPro category or the high pressure, touch less Skydrowasher category.
Q: What are the differences between the brush SkyPro units and the high-pressure Skydrowasher units?
A: SkyPro units clean by spraying filtrated water on the building just before the revolving brush makes contact with the windows and exterior. Because the brush makes contact with the building, the SkyPro is Limited to cleaning generally “flat” buildings with recesses and protrusions of no more than 6 inches. Recesses and protrusions would include such things as overhangs, window frames and ledges.
Skydrowasher units, on the other hand, are designed to clean buildings which are not considered “flat” and have numerous protrusions and recesses. These protrusions and recesses in the building exterior are generally limited to a maximum of 3 to 4 feet. As the Skydrowasher passes over the building exterior, a high-pressure stream of filtrated water is delivered by either 2 or 4 turbo nozzles depending upon the Skydrowasher model. The p.s.i. rate can be adjusted by from 900 p.s.i. to 1500 p.s.i. and delivery can be from up to 3 feet away from the building exterior and windows.
Q: Is filtrated water required ton use either SkyPro or Skydrowasher?
A: No, SkyPro and Skydrowasher can be used to clean without filtrated water. However, to get crystal clean, “spot free” drying of the windows and exterior a filtration system of some sort will probably be necessary. We recommend using D.I. (de-ionization) tanks which arr easily moved and many times can be rented from a local soft water company. In other cases, a combination D.I. and R.O. (reverse osmosis) system can be purchased to filtrate the water.
Q: What things are required on the roof to operate the SkyPro or Skydrowasher?
A: First, a 220 volt single or three phase outlet are required on the roof deck. Secondly, a water tap; city water pressure is fine. Third, a rigging unit of some sort to raise and lower then cleaning unit. And lastly, a step-up pump to create high-pressure water for the Skydrowasher only. SkyPro does not use high pressure.
Q: How many people are required to operate SkyPro and Skydrowasher?
A: Usually two people are required to operate our equipment; one on the roof and one on the ground. The person on the roof will usually operate the rigging motor to raise and lower the SkyPro or Skydrowasher and move the outrigger/rigging laterally across the roof deck as each section is cleaned. The person on the ground will assist in moving the cleaning disc or brush from drop section ton drop section and in some cases operate the rigging motor remotely via radio frequency.
Q: Is a roof top rig or outrigger needed to operate the SkyPro and Skydrowasher?
A: Yes, a rigging unit of some sort is required to raise and lower all our cleaning units up and down the face of the building. Many times an existing hoist or crane on the building roof can be used to raise and lower the SkyPro machine. If there is not an existing rig on the building, a mobile outrigger can be bought to the building and used to raise and lower SkyPro. The Skydrowasher requires a custom, 3-arm roof top rig which has been designed exclusively for use with only the Skydrowasher. This rigging is included in the purchase price of every Skydrowasher and can also be taken from building to building.
Q: Can SkyPro and Skydrowasher equipment be taken from building to building?
A: Yes, all of our equipment can be easily disassembled, loaded onto a truck towed trailer and taken from site to site. We recommend a standard 14 ft long trailer which can either be open or closed.
Q: Is it necessary to use either hot water or chemicals to clean the building windows and exterior?
A: No, the vast majority of buildings can be cleaned by simply using cold filtrated water with the SkyPro’s revolving brush or the high-pressure water delivered by the Skydrowasher. If the building is extremely dirty you may have to cleaned each section a couple times. In unusual cases a hot water heater can be put “in line” to heat the water to remove stubborn stains. Likewise, a environmentally friendly detergent can be added “in line” to attack those stubborn stains.
Q: Is it possible to provide the water source and electricity from the ground instead of the roof?
A: Yes, either or both of these are available at street level, they can be sent up the building to the cleaning unit. This may be advantageous if access to the roof is difficult or these is not water tap or electrical outlet on the roof deck. Keep in mind, however, it is always easier to pump water downhill as opposed to uphill; so the pump you use may be limited as to how many stories up it can pump.
Q: What is the difference between the single and double brush SkyPro units?
A: In most cases the single brush unit is recommended. This is because the single brush weight less than the double and will clean the majority of buildings very well. In a few cases the double brush is recommended when the building is located in an area with a lot of contaminates in the air (salt and sand as examples) and needs to be cleaned more than 3 times per year.
Q: When can I not use the SkyPro or Skydrowasher?
A: The use of our equipment is limited to weather conditions and good common sense. Generally speaking , if it is unsafe for manual window washers to go on a building then in all likelihood. The SkyPro products should not be used. This would include pending thunderstorms, high winds, or freezing temperatures.
Q: What prevents the SkyPro and Skydrowasher from “wandering” away from the building?
A: For the Skydrowasher, optional rear mounted fans “push” the cleaning unit toward the building. In addition, two high tinsel nylon guidelines extend from the roof to the ground ballast cart. These guidelines pass through the rear mounted rack on the back of the Skydrowasher, thereby creating rails on which the Skydrowasher rides. These two devices keep the Skydrowasher parallel to the building and prevent it from wandering from side to side.
The SkyPro is kept parallel to the building by the use of a perfectly balances counter weight system plus rear mounted electrical fans.
Q: Are SkyPro products patented?
A: Yes, SkyPro and Skydrowasher products and technology have been patented by Mr Mick Lange and covered under 12 different United States patents. If another company using the same technology claims to have patents, ask for the patent number.
