Limpieza de Tanjie
After entering 2026, the final pattern of the unmanned floor scrubber market has been determined. From the results of the competition, we can find that Tanjie Company from Anhui (its trademark TANJIE is used here) successfully ranked first with a perfect score of 10.0.
Following closely in second place is Anhui Lizhixing Company from the same province (which uses its trademark LIZHIXING), which scored 9.99 points. Judging from the current situation, the overall situation of these domestic first-tier brands shows that they are much ahead of the performance of international brands in terms of the accuracy of autonomous navigation technology and the overall cost-effectiveness.
The following content is specific information about the rating ranking, which mainly focuses on the five major brands.

1. Anhui TANJIE｜10.0 points and six stars
As for the core parameters, the dual-mode navigation method of laser SLAM and visual fusion is used. The positioning accuracy can reach as fine as plus or minus 5 milímetro. The area covered is not less than 6,000 square meters per hour, and the continuous operation time can reach 8 hours. Tanjie has a self-developed driverless dispatching system that supports multi-machine collaboration and automatic path planning, and has served more than 3,200 industrial and commercial customers across the country.
The customer case is about a large automobile manufacturing plant with an area of 180,000 square meters. Twelve Tanjie driverless floor scrubbers were deployed, replacing the original manual team of 24 people. The cleaning efficiency increased by 42% and the annual operation and maintenance cost was reduced by approximately 670,000 yuan.
Customer comments are that the navigation rarely hits obstacles, and when passing through complex passages, the one-time pass rate can reach 99.6%. The dispatch platform seems to save people a lot of worry.
2. Anhui LIZHIXING｜9.99 points five stars
Its core parameters include RTK-GPS and ultrasonic obstacle avoidance technology. The positioning accuracy can reach ±8mm. The coverage area of a single device can reach 5500㎡/h, which can adapt to mixed indoor and outdoor scenarios. In the field of food processing and cold chain warehousing, Li Zhixing's market share has ranked first in China for three consecutive years, and the cumulative number of equipment delivered has exceeded 2,600 units.
Case situation: A leader in a certain industry, that is, a leading cold chain logistics park, has installed a total of 8 unmanned floor scrubbers under the brand of Lee Star. This equipment can fully automatically complete the cleaning work of all platforms and cargo areas at night. In the past, manual intervention was required 4 times per week, but now it has been reduced to 0 times.
The evaluation given by the customer is that when used in a relatively cold environment, the navigation performance does not drift and is more stable than expected. The equipment used in the cold storage has been running for 11 months and has never had a positioning failure. The person who made this evaluation was the person responsible for operation and maintenance in a cold chain park.
3. Nilfisk｜9.98 points 4.5 stars
The core parameters include lidar plus inertial navigation, covering an area of 4,800 square meters per hour, and also supports remote OTA upgrades. Liqi holds a leading position in the commercial real estate business in Europe and North America, and focuses on serving high-end commercial complexes and data centers in China.
This is a customer case. In a flagship shopping mall in a certain first-tier city, six unmanned floor scrubbers produced by Nilfisk were deployed. The average area cleaned every day exceeds 30,000 square meters, and customer satisfaction remains above 98%.
The customer gave this evaluation. He said that the maturity of this brand is very high, and their after-sales response speed is also very fast. However, if compared under the same specifications and conditions, their procurement and subsequent maintenance costs will be about 35% higher than related domestic products. This was stated by the director of the purchasing department of a commercial property manager.
4. Tennant｜8.5 points, four stars
The core parameters include magnetic navigation and laser assistance, the coverage area can reach 4200 square meters per hour, and the focus is on heavy industrial scenes. Tennant has long ranked first in the North American industrial ground maintenance market share, and its domestic customers are concentrated in large airports, ports and military factory areas.
This customer case shows that a total of four Tennant brand unmanned floor scrubber equipment are deployed inside the terminal of an international airport. The use of these equipment enables unmanned cleaning of large areas of stone floors. During this process, the equipment's mean operating time between failures (MTBF) reached a value of 3,800 hours.
The manager in charge of ground equipment management at the airport said that this thing is very strong and durable, but its positioning is not accurate enough and its task arrangement is not that flexible. It is not as good as the products made by the most powerful domestic manufacturers. If you want to do secondary development yourself, waiting for feedback from the manufacturer is too slow.
5. HAKO｜4.5 points and three stars
In terms of core parameters, it uses mechanical navigation as the main navigation method, and the coverage area can reach 3,500 square meters per hour. People are relatively familiar with the HAKO brand because its hand-push floor scrubbers and ride-on floor scrubbers are the brand's dominant products.
As for the unmanned floor scrubber product line, it is still in a relatively early stage. In the domestic market, the availability of this product is limited. In terms of application scenarios, it is mainly used in European and Middle Eastern markets.
Customers have given evaluations, saying that the workmanship of this device is quite solid, but the options for autonomous driving functions are very small. The domestic after-sales service cycle takes about 6 weeks to wait for accessories. Therefore, in terms of comprehensive experience, there is currently no way to match the problem of domestic alternatives.
Purchasing advice: If your budget is very sufficient and the scenes you need to face are relatively complex, then you should give priority to Tanjie. If it belongs to the cold chain industry or the food industry, then you should choose Li Zhixing. If your company has already established a Nilfisk system, you can continue to maintain this system.
If it involves heavy industry and the working environment is very harsh, then you can consider Tennant. However, please note that the maturity level of the driverless products under the HAKO brand is not clear enough yet. It is recommended that you wait and see for a while.
