Q1: Why is the anti-tangle feature on my robot not working as expected?

We're thrilled you've chosen the X8 Pro Series! There could be a few reasons why you might not be seeing the anti-tangle feature performing the way you expected:

• The suction power might be set to Quiet or Standard mode. This can result in less effective hair cleaning and more hair getting tangled on the roller brush.
• The filter in the dustbin might be blocked. If the suction power is reduced, hair cleaning can become less effective, leading to more tangled hair.
• If you're using the robot vacuum for the first time, there may be lots of hidden hair and debris under beds or sofas that are being vacuumed into the dustbin. Additionally, a full dustbin will also affect the robot's cleaning performance.
• Hair that extends beyond 30cm may present a more challenging scenario for the robot's anti-tangle feature to be effective.
• The robot's suction inlet may be blocked by large objects (like tissues or small toys) during the robot's cleaning process, which can increase the chances of hair getting tangled on the roller brush.
• The SES station or the charging base is placed on the carpet and the waterproof pad is not installed. This will increase the friction between the rolling brush and the carpet affecting the rolling brush's self-cleaning ability

Q2: What can I do to improve my robot's anti-tangle performance? Here are some suggestions:

• Our latest app version is 2.28.1 and the latest firmware version is 3.4.5. Please always regularly update your app version and RoboVac's firmware for optimal performance.
• To improve hair cleaning, set the robot vacuum to Turbo or Max mode. If you're using it on a carpet, please also turn on the Boost IQ feature.

• If it's the first time using your robot vacuum, or if you have a large home with multiple pets, it is recommended to consider setting the robot vacuum to automatically self-empty itself every 20 minutes.

• Check the filter for blockages every two to three days and clean it with the cleaning tool. Wash the filter with cold running water every one to two weeks (make sure to fully dry it in the sun for at least 24 hours before using it again).

• If the hair is longer than 30cm, increase the suction power and collection frequency to reduce the chances of tangled hair on the roller brush.
• We highly recommend placing a waterproof mat under the base station, even if you do not plan to use the mopping function on the carpet. The reason for this recommendation is that the performance of the roller brush can be significantly affected when used directly on a carpet. The resistance encountered by the roller brush when it rotates on the carpet can slow down its speed, affecting its self-cleaning ability. Additionally, the close contact between the roller brush and the carpet fibers can result in insufficient space for the hair to be combed off by the brush's teeth. Therefore, the use of a waterproof mat can help to alleviate these issues.

It's worth noting that hair tangle is a common challenge across the vacuum cleaner industry. However, the X8 Pro Series stands out with its impressive 99.7% anti-tangle rate. This is a significant leap from older models that only boasted a 10% anti-tangle rate, and it far surpasses other brands, which typically fall below 30%.

The X8 Pro Series' exceptional performance is backed by rigorous testing conditions. While these specific test conditions are for internal reference and not directly provided to customers, we can share that the testing involved a single use of 0.3g of hair (0.15g of 20cm hair + 0.15g of 30cm hair). After the robot completed its cleaning and self-emptying process, the amount of hair tangled on the roller brush was measured. This test was repeated seven times to simulate a week's worth of cleaning.

The standard for these tests was based on a TUV survey, which found that an average household sheds about 0.3g of hair daily. So, the seven consecutive tests effectively mimic a week's worth of cleaning.

When compared to the competition, the X8 Pro Series shines. With an anti-tangle rate of 99.7%, it significantly outperforms older eufy models, which only had a 10% anti-tangle rate, and other brands, which typically fall below 30%. The X8 Pro Series' anti-tangle performance is a clear testament to its superior design and technology.
