Chores have been a painful daily routine of ours that demands labor and time. A survey conducted by the University of Michigan showed that in American families, women spend 890 hours on chores each year. That is a whopping 17 hours each week! Moreover, research has shown that the burden of chores on women grows heavier once they have children. For years, people have been seeking ways to reduce the time spent on chores. Vacuum cleaner was the first revolution to free human labor. It sucks dry waste such as dust into the dust cup through the high-speed motor. Robot vacuum has also emerged in recent years. It's suitable for cleaning under the bed and sofa. But neither of them has taken the tediousness out of housework completely because they can only handle the dry waste. Once there was wet waste combined, people had to deal with the wet and dry waste separately. The time spent on chores can not be reduced significantly in this case. The new cleaning tool cuts cleaning time by 2/3 According to tests, cleaning a 200sqm house takes 100 minutes in the traditional way (55 minutes of sweeping + 30 minutes of mopping + 15 minutes of mop washing) or 75 minutes with regular vacuum cleaners (30 minutes of vacuuming + 30 minutes of mopping + 15 minutes of mop washing). It's Redkey's responsibility to meet customer needs. Finally, after a year of research and development, there was the Redkey W12 wet and dry vacuum cleaner. Wet and dry vacuum cleaner is the combination of the vacuum cleaner, electric mop, and mop washing. It vacuums, mops and washes itself. In addition to vacuuming, it can also take care of heavy moist waste. It's finally fulfilled people's wish to shorten the cleaning time — it takes only 30 minutes to clean the 200sqm house mentioned above with the Redkey W12 wet and dry vacuum cleaner.
