The water pipe has the magic function of 3 times automatic expansion: it can be automatically extended by 3 times after the water is connected, and automatically retracted to the original length after the water is turned off.2. Wide range of applications (used for car cleaning, indoor and outdoor door and window cleaning, floor cleaning, gardening and gardening spraying, household hygiene cleaning, etc.).3. Small size and easy to store, just a small storage box.4. Rotating water spray adjustment design, with 7 patterns of water discharging methods.5. Internal pressurization, long range.6. Easy to install and disassemble, saving time and effort, fast installation in three seconds.7. With water-passing foam brush, it is convenient to clean, protect the cleaning surface from damage, and save time with efficient synchronization8. Good quality, long service life, high-elastic inner tube, high-density cloth cover, no knots, no rigidity, and small folding volume. Super wear-resistant.9. The spray gun has a humanized design and attention to details. The triangular metal ring at the spray head can effectively support the switch, so as to realize automatic long-time spraying and save effort.Precautions:1. The length indicated on the link is the length of use after 3 times of extension after passing water. The effect of extension is related to water pressure. Too low water pressure will affect the elongation effect of the water pipe. It is recommended to choose a longer one 2. Use water pipes on smooth roads as much as possible. After use, the water in the water pipes will be drained cleanly. Keep them properly to increase the service life of the water pipes.The telescopic tube has a magical feature: when it is not filled with water, its length is only one third of that after filling with water.Therefore, the goods you received are: unsealed state, after the water is automatically expanded and stretched
