The split set includes 3 \"Magic Window Groove\" brushes, 4 high-density cleaning sponges. These are suitable for a variety of cleaning tasks, such as cleaning window tracks, showers, and car air conditioning vents. In addition, they are easy to replace. **Improved material technology** The non-slip ABS handle has a ribbed grip that fits comfortably in the hand and prevents it from slipping. The scrubbing sponge is removable, foams easily, and has strong cleaning power. **Optimized cleaning structure** The 3 mm deep, V-shaped groove on the sponge's surface perfectly adapts to the contours of the track being cleaned. The narrow, slotted design of the mini brush head reaches into the smallest corners – such as those found in window blinds or keyboards – increasing dust removal efficiency to 98%. **Convenient and hygienic maintenance** The sponge can be quickly replaced in just 3 seconds to prevent bacterial growth. The entire tool kit is washable and can be disinfected; the materials are heat-resistant up to 120°C, making them ideal for use in humid environments such as kitchens and bathrooms. **Versatile use** From household window tracks and tile joints to car air conditioning vents and buttons on electronic devices, this set offers a comprehensive solution for cleaning hard-to-reach corners – all while requiring minimal storage space.
