||PRODUCT: Unger Hi-Flo Kit
At a glance: A kit that turns a standard pole into a waterfed brush.
Pros: Can cover large areas of glass FAST. Ideal for windows with difficult access. Low pressure cleaning with brush agitation is sometimes preferable to high-pressure where water ingress is possible. Excellent for washing down painted surfaces.
Cons: Can be difficult to manage on poles over 36 feet, though this is mostly a function of the pole rather than the kit. Ideally, operator needs wet-weather gear due to falling water if used on high glass; can't use where pedestrian traffic is high for the same reason. Results can vary on different glass. Finished result not quite as good as a squeegeed finish (unless you're a bad squeegee-er!); some light water-spotting usually evident. Can be tiring to use for extended periods.
This machine is pretty well thought out.
It turns a standard pole into a superior waterfed pole quickly & easily, with some added benefits. Some waterfed poles fill the entire inside of the pole with water, which feeds to the top & out the brush. It works, but makes for a very heavy pole; hard to lift, hard to work with.
The Unger H-Flo kit solves this problem by supplying water to the brush via a quality small-diameter high-pressure line (the green hose in the picture) that attaches to your pole with clever velcro straps. Water is supplied by standard garden hose to the detergent tab holder/mixer via a supplied inline tap. Water/detergent mix is then passed to the small-diameter line and on to the brush. Detergent supply can be adjusted via a dial on the detergent tab holder. Unger's detergent tabs last about 20 minutes, depending on rate of water flow- which can be adjusted with the supplied in-line tap.
Most importantly in these water-conscious times, water usage is low; lower than high-pressure gerni-type equipment, so getting that permit from the water authorities should be no problem. I've measured a usage of around 3 litres per minute with mine.
The brush, incidentally, is of excellent quality. It sweeps right to the edge, and cleans the glass very well indeed. It also features a rubber bumper to protect window frames.
Expect plenty of use before the brush eventually wears down on the edges, which means that it won't do as good a job as it used to. No problem- log on to Squeegeesonline & order another, & keep the old one for washing down walls- which incidentally the Hi-Flo is great for.
The supplied gooseneck gets the brush over most window ledges, eliminating ladder work.
Expect to clean windows 2-5 times faster than traditional methods- this kit will pay for itself in no time.
Finish when dry looks like window was cleaned yesterday, & got rained on overnight. Explain this to customers so they'll know what to expect, & you shouldn't have any problems.
When cleaning glass, it's important to let the water flush the loosened dirt off the glass, so it's best to work from bottom to top, rather than the usual window-cleaning technique of working from top-to-bottom. When cleaning large windows, clean in an up-and-down motion about 4 foot high (that's about 1.25 m. for you young'uns) starting at the bottom from one side to the other, lengthen the pole up 4 feet, & now work back to the other side. Repeat as necessary. This method lets you see where you've cleaned- working from top to bottom means that water runs over the whole window, & makes it hard to see what's clean & what isn't.
If you want to get real fancy, hold the brush completely off the glass & move it along the top of the window for a final flush.
WHAT ABOUT WATER RESTRICTIONS?
We've had no trouble obtaining permits from the relevant water authorities to use the unger Hi-Flo.
Contact the water authority in the area you wish to work in, and ask for a Water Restrictions Exemption Request form. The forms can usually be downloaded from the authority's website as well.
When filling out your application, be sure to state that yuou wish to use the Unger Hi-Flo kit, that it is connected by garden-type hos to a tap, and that it is a low water-usage device. We've measured a flow of 3 litres per minute; most high-pressure water cleaners use much more than that. You might also wish to mention that a high-pressure cleaner is not suitable, due to risk of water ingress around windows, etc.
