First, check whether the sealing strips are aging or damaged. If so, they should be replaced promptly. Then, check whether the drainage holes of the windows are blocked; if blocked, clean them to ensure smooth drainage. If water is leaking through the gap between the window frame and the wall, reseal the gap with caulking.

The maintenance cost of smart system windows is slightly higher than that of ordinary windows. Components like sensors and motors in the smart system require regular inspection and servicing to ensure normal operation. If faults occur, professional technicians may be needed for repairs, which can be more costly. Additionally, battery-powered smart windows need regular battery replacement.

For general stains, use a damp cloth with a small amount of detergent or glass cleaner, then wipe dry with a clean dry cloth. For stubborn stains, specialized tools like glass scrapers or wire brushes may be used, but take care not to scratch the glass. For frames, wipe with a damp cloth and avoid corrosive cleaning agents.

Battery life depends on factors like battery type, usage frequency, and the smart features being used. Generally, regular alkaline batteries last from a few months to about a year, while lithium batteries have a longer life, often over a year. If the smart window is used frequently or power-hungry features are often enabled, the battery will deplete faster.

If the rust is minor, gently sand the rusty area with sandpaper and apply anti-rust oil. If the rust is severe and affects normal operation, replace the fittings in time to ensure smooth and safe use. During regular use, try to keep the doors and windows dry to prevent prolonged exposure of hardware to moisture.
