"It promises flagship suction for a fraction of the price; physics says otherwise."
The '450W 40KPA' figures describe a motor with respectable power on paper but a theoretical suction capacity that will not translate to real-world performance at the cleaning head.
This is for the buyer seeking the most features-per-dollar under $100, who understands the performance will not match the marketing. The large dustbin and removable battery are practical upsides for small apartments or secondary use.
Anyone needing reliable deep cleaning for medium-to-high pile carpet should skip this. Buyers prioritizing longevity and proven performance should budget for an established brand, which will cost at least two to three times more.
