Narwal has introduced two robot vacuum and mop models, the J4 and J4 Lite. The J4 is the flagship model, priced at 4299 yuan ($589), while the J4 Lite is more affordable at 3299 yuan ($452). The Narwal J4 robot is available in two versions: a manual water tank version and an automatic water supply version.
Narwal J4 and J4 Lite Robot Vacuum key features:
One problem many users have with robot vacuums is the struggle with hair getting tangled. The J4 has tackled this by using a strong suction of 7800Pa and a special U-pipe air system. Its roller brush can easily remove hair, making it great for households with pets or long-haired members. It has passed tests showing it can pick up almost all the hair and leaves no hair behind on the brush.
Mopping is another key feature of the J4. It can adjust its pressure based on the floor type to clean well without harming the floor. If the mop pad gets very dirty, the robot can clean it by itself. It has a unique dirt detection system to ensure thorough cleaning. The J4 also introduces a new kind of dustbin which combines with the filter. This helps dry out the waste quickly and reduces bacteria growth. Plus, there’s no need to transfer trash, which avoids extra mess.
The base station of the J4 vacuum cleaner is loaded with features. It can wash the mop cloth, refill water, add detergent, and dry the cloth with hot air. It can even clean itself. The robot can be controlled through an app where you can specify rooms and add furniture details.
Mapping is crucial for these robots. The J4 uses the IPS4.0 Whale Sense Perception System with three lasers to measure space and avoid obstacles efficiently. It also can remember dirty areas and clean them multiple times if needed. Edges and corners get special attention too. For carpets, the J4 can adjust its suction and avoid long carpets.
The J4 Lite, though cheaper, still has a strong 6800Pa suction and can handle hair well. Its dustbin can hold up to 1L and has an integrated filter.
