Reviews last updated: July 2026 · How we calculate this

What customers like about Electrolux Pure i9.2 PI92-4STN

  • Excellent ability to cross obstacles and door thresholds up to 2.2 cm with ClimbForceDrive
  • Unique triangular shape reaches and cleans corners effectively
  • Intelligent 3D Vision navigation and effective obstacle detection
  • Powerful suction automatically adapts to the floor type
  • Intuitive mobile app with easy setup and operation

What customers don't like about Electrolux Pure i9.2 PI92-4STN

  • Rather limited dustbin capacity requires frequent emptying
  • Average battery life on very dirty floors or thick carpets at maximum power
  • Height can prevent it from fitting beneath very low furniture
  • Navigation may sometimes appear hesitant in very complex room layouts

Verdict

The Electrolux Pure i9.2 PI92-4STN is a cordless, bagless robot vacuum featuring a unique triangular Trinity Shape designed for optimal corner cleaning, a 14.4V lithium-ion battery, a 0.7-litre dust container capacity, and a noise level of 75 dB. It measures 32.5 x 28 x 8.5 cm and utilizes an advanced 3D Vision laser and camera navigation system along with ClimbForceDrive technology to cross obstacles up to 2.2 cm. Key advantages include methodical, obstacle-avoiding navigation, superior corner performance with its front-mounted 21 cm XL brush, and remote control via a Wi-Fi-connected mobile app. However, its primary drawbacks are a relatively short run time of approximately 40 to 70 minutes per charge depending on the power mode, a long 2.5-hour recharge cycle, a high retail price point, and a lack of integrated advanced smart-home integrations compared to rival models.
