I've tested a lot of vacuum cleaners lately and some have convinced me. Nothing but KING-LINK Cordless Vacuum Cleaner (UOOGOU SC-1609 Cordless Vacuum Cleaner). The UOOGOU SC-1609 was a vacuum cleaner intended to compete with the Dyson V11, assembled in April 2021 and launched in August 2021. So I will go through the ups and downs of this UOOGOU SC-1609 vacuum cleaner. .BENEFITS: Not only can the dust bin be opened from the bottom, but the entire bin can be removed for easy storage. Extension extends/retracts. The suction can be so strong that I was able to lift the whole vacuum just by using the suction on my hand - yes, that is strong suction. The parts slide together easily and snap into place without much effort. It's the same as my expensive vacuum cleaners. The battery is detachable and can be charged outside the vacuum cleaner and swapped out on the fly. Every part can be washed, including the brushes, and there are tools to clean the brushes from the hair. .This vacuum cleaner comes with a full manual with detailed cleaning instructions. Multi-stage suction power regulation, with good suction power even at the lowest level. Excellent battery life at lower suction levels (I got about 30 minutes cleaning in auto mode with the roller nozzle). There is an automatic suction mode that is very good at recognizing when the suction power needs to be adjusted. Low noise level during low to medium suction levels. low rooms. In addition, the roller attachment works well in corners and edges. CONS: The battery life at the maximum setting is very short (I had about 6 minutes of use). Even if you don't need it often, you'll need a second battery if you want to use it. This vacuum cleaner was only released in August, so it is very difficult to find replacement parts. This is actually the BIG end of the list (which is why it loses a star). Hopefully KING-LINK will release more parts for sale on Revain as well. The tool for padding the rotator is missing. While the parts appear to be well-made, they're a bit more "plasticky" than other vacuums in this price range. More sophisticated than traditional vacuums with capacitive adjustments and advanced features. Overall this is an amazing vacuum cleaner and a lot of great ideas have gone into its design. For this price I can't recommend it enough. for now. as soon as parts are released for it.
