Reviews last updated: July 2026 · How we calculate this

What customers like about eufy RoboVac G40

  • Strong 2500 Pa suction power effectively picks up surface debris from hard floors and low-pile carpets
  • Systematic row-by-row pathfinding navigation covers rooms much more efficiently than random-bounce models
  • Ultra-slim 2.85-inch profile allows it to navigate and clean underneath low furniture and tight gaps
  • Operates quietly at around 55 dB, allowing it to run without causing major household disruptions
  • Easy remote control, scheduling, and automation setups through the user-friendly eufy Clean app
  • Affordable price point makes it an excellent high-value, entry-level smart vacuum option

What customers don't like about eufy RoboVac G40

  • Lacks advanced LiDAR or laser mapping, meaning it cannot save permanent room layouts or set digital no-go zones
  • Struggles to climb onto thick or shaggy rugs and can occasionally get stuck on low door thresholds
  • The physical mesh filter is difficult to wash and clean thoroughly when fine dust gets trapped inside
  • Struggles with deep-cleaning heavy pet hair or embedded dirt out of medium-to-high pile carpeting
  • Replacement parts and official replacement filters can sometimes be difficult to source or find in stock
  • Battery life is on the shorter side, occasionally requiring multiple recharges to finish cleaning larger floor plans

Verdict

The eufy RoboVac G40 is a budget-friendly robot vacuum featuring 2500 Pa of suction power, systematic planned pathfinding navigation, and an ultra-slim 2.85-inch profile that easily slips under low furniture. Key advantages include its quiet 55 dB operation volume, a 100-minute maximum runtime, and smart app and voice control compatibility with Amazon Alexa and Google Assistant; however, it lacks highly accurate LiDAR-based advanced mapping and does not support virtual no-go zones or physical boundary strips.
