The Korea Consumer Agency on Thursday listed a number of vacuum cleaners ranging from premium to low- and mid-cost products to better inform consumers of their efficiency relative to their price.

Premium brands such as Nilfisk’s X300C, Dyson’s DC37 and Siemens’ VSZ61240 cost more than 700,000 won with a wide range of functions, but they lack efficiency in terms of suction power and noise when compared with Samsung Electronics’ VC-UBJ937, which costs around 382,000 won, or other lower-cost brands, the agency said.

The KCA compared eight low- and mid-priced vacuum cleaners with 11 premium brands for efficiency and performance, and noted that more expensive products did not necessarily perform better.

It said that Ace Electronics’ AVC-950, Philips’ FC8144, LG Electronics’ VC4014LHAM and Samsung Electronics’ VC331LWDCUD outperformed premium brands.

Samsung’s VC331LWDCUD, costing around 130,000 won, topped the list in terms of suction power efficiency, followed by LG Electronics and Philips.

They even have greater power efficiency than Nilfisk’s X300C, the most expensive product on the list at 819,000 won.

Samsung’s VC-UBJ937 was also picked as the best-performing product among premium brands in terms of power consumption and noise, according to the agency.
