The safety hazards are akin to a "high-altitude adventure."
For families living above the third floor, cleaning the exterior glass can be a "heart-stopping moment"—leaning out of the window leaves your legs trembling, your hands gripping the frame tightly, afraid to let go. Even using a double-sided squeegee, you can't help but worry that insufficient magnetic force might cause it to fall. Worse still, in high-rise environments with strong winds, a single misstep could lead to an accident, with cases of injuries from window cleaning at heights reported every year.
A thankless task that leaves glass dirtier than before.
Manual window cleaning always falls victim to the "streak curse": wiping with a cloth leaves streaks, newspaper cleaning leaves ink stains, and detergent makes the glass attract dust faster. Even more frustrating is the dust in the crevices of the window frame—spending half an hour with an old toothbrush still leaves residue behind. The freshly cleaned glass gets re-contaminated within days, making an hour of effort only result in brief cleanliness.
Helpless against stubborn stains.
Stubborn stains like bird droppings, rain spots, and dried soy sauce stains require 5-6 rounds of scrubbing and careful handling with a scraper. Applying too much force risks scratching the glass. For Low-E coated glass in particular, regular cleaning methods can wear down the coating, reducing its thermal insulation performance.
