TEK is an independent electrical appliance company under Ecovacs, which mainly develops vacuum cleaners and their sub-categories, and has three product lines: cordless vacuum cleaners, cleaning machines, and mite removers. Although the market performance of TEK is not as good as that of Puppies, it has invested more resources in product research and development, and has a mature production chain with very strict quality control. In the 2016 evaluation of the Shanghai Municipal Consumer Protection Commission, the TEK ZW4730 received a full five-star recommendation in both suction power and dust emission, and the floor and carpet dust removal performance was good.
 
There are many models of TEK handheld vacuum cleaners, the price is more than 1,000 yuan, the dust cup is used for dust storage, and the standard HEPA10 filter screen is equipped with a dust filter, and the dust filter effect is slightly inferior to that of HEPA13. The whole line of the product is equipped with dual batteries, which can be used alternately and has a longer battery life. In addition, it is also more intimate to have a one-button emptying device.
 
The difference between A6 powerhead and AK66 is about 200 yuan, the suction power and dust cup capacity of the two remain the same, the battery life of AK66 has changed from 40 minutes to 50 minutes, and the main suction head has added LED lighting. The number of tips is also more extensive, and cleaning is more targeted. If the floor at home is made of marble or high-specification wood, you can consider the A10 Smart, and the main suction head is a soft velvet LED electric floor brush, which is more labor-saving and less likely to scratch the floor.
 
In comparison, the price of A10 hero is about 2700 yuan, the battery life in standard mode reaches 60 minutes, there is a power indicator, and the configuration storage base is also very user-friendly. If you pursue cost-effectiveness, you might as well buy A8 hero, which costs about 2600 yuan, and the important parameters remain unchanged, without the electric mattress cleaning suction head and dust removal brushes.
 
Unlike the puppy's optimism about the mite removal device, TEK maintained a cautious attitude when launching this category, with three models all under 1,000 yuan, UVC351 only has a mite removal suction head, and RUC86 can also be equipped with a flat nozzle and a brush, which is suitable for pet lovers.
 
In 2017, TEK launched the industry's highest five-year warranty commitment, breaking through the industry's one-year warranty tradition and enhancing brand awareness, after all, Dyson only has a five-year warranty for its horizontal vacuum cleaners and only two years for handheld products.
