We are now without a helper so we started investing in technologies to help out with our housework. This robot vacuum cleaner is one of them. After reviewing quite a number of robot cleaners, we decided to buy this which only costs us $200 after all the online discounts.
In this video, you can see it vacuuming by the side of the objects without knocking into them, going under chairs and finding its way home to recharge. It can also vacuum and mop at the same time. With one charge, it can vacuum for more than 2 hours. I would say it's a good investment so far.
