"A lightweight tool for hard floor touch-ups, not a serious whole-home vacuum."
The 250W brushless motor is a standard component for this price, providing just enough power for surface cleaning on hard floors. The 40-minute runtime only applies to an eco-mode you will likely never use.
This is a fit for someone with a small apartment of mostly hard floors who needs a cordless option for daily, quick cleanups. Consider it a powered broom, useful for the kitchen and entryway, but not as a primary vacuum.
Anyone with medium-pile carpet, pets, or a home larger than 800 sq ft will find the performance and battery life frustrating. If you're trying to replace a corded vacuum on a budget, this is not the solution.
