"It lists the features of a premium vacuum and the specs of science fiction."
The '55kPa 650W' headline describes performance levels that are physically unrealistic for this product class and price. Its actual cleaning power will be comparable to other budget cordless vacuums, not the high-end industrial machine the numbers suggest.
This product is for a buyer on a strict budget who values a long list of convenience features—like auto-mode, a self-standing body, and a flexible hose—and is willing to gamble on an unknown brand with unverifiable performance claims.
Anyone prioritizing proven cleaning performance, long-term reliability, and customer support should avoid this. The combination of an unknown brand and highly suspect specifications points to a high-risk purchase.
