    Firstly, the performance of the 405 is truly impressive. It does a fantastic job of picking up everything on both my floors and carpets. The suction power is noticeably stronger than the j series, which is a big plus. Additionally, the new rotating mopping pads are excellent at tackling stains and leave my floors with a beautiful shine. Navigation is also amazingly great, new lidar is a big change but if you have small objects laying around or a lot of wires around go with the 505 instead.

    The base of the 405 is another highlight. It not only allows the robot to operate autonomously for days but also self-cleans, eliminating the need for frequent maintenance. This is a significant plus over other brands, where you need to clean the mopping pad system often.

    However, there is one aspect I'm not entirely sold on – the refresh system for the mopping pads. Since there is no water tank on the actual robot, you have to decide via the app how many square feet the robot will clean before returning to the base to refresh the pads and self-clean. This process takes a bit more time, especially if you have a large area to cover. But I do see the advantage of this system, as it prevents spreading filth around, which can happen with models that have a water tank directly on the robot.

    Lastly, the app has its pros and cons. While it offers some great features, there is definitely room for improvement. I'm hopeful that we'll see some updates and enhancements to it in the near future.

    All in all, for the price, the 405 is a strong 5-star product. It offers great performance, a low noise level compared to the j series and requires minimal maintenance.
