Short answer: for most exterior glass, a water-fed pole gives you a cleaner result for less money. For interior windows and anyone who wants a hand-detailed finish, traditional hand washing wins. The best companies use both and match the method to the window.
If you have called around for window cleaning in Charlotte, you have probably heard two very different descriptions of how it gets done. One company shows up with buckets, mops, and squeegees. Another runs a long pole from the ground with water coming out the top and never touches a ladder. Both can leave your windows clean. They just get there in different ways, and that difference shows up in the price and the finish.
Here is how each method actually works, where each one is the right call, and how to know what you are paying for.
What is water-fed pole cleaning?
A water-fed pole is a long telescoping pole with a soft brush on the end and water running up through it. The water is not regular tap water. It runs through a filter first that strips out the minerals and dissolved solids, so what reaches your glass is purified, or "deionized," water.
That purified water is the whole trick. Tap water around Charlotte carries a lot of dissolved minerals, and those minerals are what leave the chalky spots when water dries on glass. Take the minerals out and the water has nothing left to leave behind. The technician scrubs the glass and frames with the brush, rinses with the pure water, and walks away. The glass dries on its own, clear, with no spots and no towel marks.
A few reasons it has become the standard for outside work:
- It reaches second and third story windows from the ground, which is safer and faster than ladders.
- The soft brush scrubs the glass to safely dislodge dirt and debris, and it cleans the frames and sashes too, not just the panes.
- It uses no metal blades and no harsh chemicals, so it is gentle on screens, seals, and the plants below.
The trade-off is that it cleans by safely scrubbing and rinsing rather than wiping. On glass that is dusty or has normal grime, that is all you need. On glass with something stuck to it, like paint specks, heavy mineral buildup, or a thick coat of spring pollen, a rinse alone might not pull it off in one pass.
What is hand washing?
Hand washing is the method most people picture. The technician wets the glass with a soapy solution, works it by hand with a scrubber, pulls the water off with a squeegee, and wipes the edges with a cloth. It is slower, and anything above the first floor usually means a ladder.
What you get for that extra time is control. A person with a squeegee can feel a spot that will not budge and go back over it. They can detail the corners, wipe the sill, and catch a streak before they leave. For interior glass, hand washing is really the only option. You cannot run a wet pole through someone's living room, so inside windows are always done by hand with care taken around furniture and floors.
Hand work also tends to be the right choice for:
- Interior glass, which is always cleaned by hand.
- First-floor and easy-access glass, where a ladder is not needed and the hand finish is quick.
- Customers who want the white-glove finish and the extra attention that comes with it.
So which one is better?
It depends on the window, not on which company you ask.
Water-fed pole is the better call for exterior glass on most homes and buildings, upper-floor windows, frames, and screens, and anywhere reach and safety matter. It is faster, so it usually costs less, and the purified-water finish on outside glass is genuinely excellent.
Hand washing is the better call for all interior glass, glass with stuck-on buildup that needs scrubbing, and any job where you want the most detailed finish possible.
French and divided-lite windows take extra attention either way, because of all the small panes and the grids between them. On the outside we usually reach for the water-fed pole on these, since the soft brush works each little pane and the grid without the risk of a blade.
A company that owns only one of these tools will tell you their way is the only way. In practice the right answer is usually both. Exterior glass gets the pole. Interior glass gets the hand treatment. Tricky windows get whatever they actually need.

Frequently asked questions
Does water-fed pole cleaning really leave no spots?
Yes, as long as the water is properly purified. The spots you see when windows air-dry come from minerals in regular tap water. A water-fed system filters those out, so the water dries clear. That is the entire reason the method works.
Is hand washing worth paying more for?
For interior glass it is not really optional, since that is how inside windows are always done. For exterior glass, the upgrade is worth it if you want a hand-detailed finish. For everyday outside cleaning, including French-pane windows, the water-fed result is excellent on its own.
Which method is better for a two-story home in Charlotte?
For the exterior, a water-fed pole is usually the better choice. It reaches the upper windows safely from the ground without ladders leaning on your house, and the purified-water finish handles our area's hard water and pollen well. Interior windows on both floors are done by hand.
