"Claims premium power on a budget battery, a fundamental mismatch of physics and price."
The 680W motor and 55kPa suction figures are meant to compete with premium models on paper, but the battery's energy capacity is typical for a budget vacuum. Expect actual performance that aligns with the sub-$150 price, not the superlative specs.
This is for a buyer on a strict budget who needs a basic vacuum for hard floors and light messes. If you value a large dustbin and a modern-looking display and are willing to ignore the unverifiable performance claims, the low price is the main draw.
Anyone needing to deep-clean carpets or expecting performance that matches the advertised numbers should skip this. Buyers who prioritize longevity and the ability to buy replacement batteries or filters in two years should invest in an established brand.
