ILIFE A4s Robot Vacuum—100+ Min Runtime, Budget Pick

The ILIFE A4s is a budget-friendly robot vacuum engineered for hard floors and low-pile carpets. It features 2000Pa suction and gyro-based random navigation, delivering adequate everyday pickup without the mapping precision of LiDAR rivals. The standout is 100+ minutes of runtime on a full charge—among the longest in its price bracket—coupled with quiet operation and a slim profile ideal for under-furniture access. It self-charges to its dock but lacks a self-empty bin; you'll empty it manually every 2–3 weeks depending on home size. The app provides basic scheduling and remote start, with no mop or advanced obstacle avoidance. Suited for single-floor, pet-friendly homes where budget matters more than smart mapping or premium build. Community feedback is mixed: praised for value and runtime, criticized for getting stuck on dark rugs and random-navigation inefficiency in larger spaces.
