I'm sorry to hear that you're experiencing issues with the sensors on your 2NICE WT10 robot vacuum cleaner. If the sensors are not working properly, it could be due to a variety of factors, such as a mechanical issue or a software glitch. I would recommend checking the manufacturer's troubleshooting guide or contacting their customer support for assistance. In the meantime, if you're unable to get your vacuum working again, you may want to consider purchasing a replacement or contacting the retailer or manufacturer for a warranty repair or replacement. It's always a good idea to keep the sensors and other components of your robot vacuum cleaner clean and well-maintained to help prevent issues from arising in the first place. Regularly cleaning the sensors and other parts of the vacuum can help to ensure that it functions properly and efficiently. I hope this information is helpful. If you have any further questions, please don't hesitate to ask. cnl
