Verdict

The Electrolux Purei8 PI81-4SWN is a connected robot vacuum cleaner featuring a distinctive triangular Trinity Shape™ design and advanced 3D Vision laser-and-camera navigation to map rooms and bypass obstacles seamlessly. This autonomous model delivers systematic cleaning across multiple floor types, utilizes three distinct cleaning modes, boasts a 0.7-litre bagless dustbin, and can overcome thresholds up to 2.2 cm high using its ClimbForceDrive™ system. Major advantages include intelligent pathing without repeated passes, convenient smartphone app programming, automated recharge-and-resume functionality, and an washable exhaust filter that minimizes recurring costs. However, it is limited by a relatively short battery runtime of up to 60 minutes, a lengthy 210-minute charge time, a lack of built-in mopping capability, and a tendency to struggle with tangled cords or tightly spaced furniture legs.
