The goods arrived almost fully charged. I charged the vacuum cleaner, the indicator is red and green when charging. Three indicators on the side do not light up when charging. After replacement and use, the three side indicators turn green, showing the charging status and power. Once the vacuum is in normal mode, press again and the power will increase, another press and it will turn off. To turn it on you have to hold the button down for a little bit and then it will turn on. You can't just press fast, nothing happens. The machine drains the battery quickly and charging is not fast, but not as slow as other brands either. I will add more details on full charge usage time and full charge time. The only complaint I have is that the car and accessories should be easy to store "together". There's no room for a cord or accessory, and I've already lost the cord from another portable vacuum because there wasn't room to store that cord either. I had to order a "lifeline". They are specific to the machine, a few. Without a label or logo on the charging cable like cell phones to just plug in your devices to charge, this is really disappointing. I have a ton of charging cables that look the same. In this case, it's just a USB-C cable with no connector, so it's not a big deal, but considering it's such a small cable and the brackets are small too, it could easily make a better stand with an extra one corner give storage. everything together and ready to use. The unit has a 'cap' which then acts as a base to support the vacuum cleaner when not in use, but that could be better. , and quick cleaning around the computer, and carpet edges, window sills and a sliding door frame, which is difficult to clean, but makes it light and strong enough. No louder than a normal vacuum cleaner. 5 Stars.
