iRobot's comeback robot — best-in-class pet hair handling and smart obstacle avoidance at a competitive $499 street price, but suction can't match the Chinese competition.
After two weeks of daily runs in a two-dog household, the dual rubber extractors on the 505 remained completely hair-free -- not a single strand wrapped around either roller. PrecisionVision AI catches pet waste before the robot drives through it, which alone is worth the price of admission for dog owners. The PerfectEdge extending mop arm reaches wall edges that spinning pads on round robots miss entirely. Where iRobot loses: 7,000Pa cannot compete with Chinese robots offering double or triple the suction at $499. Cold-water mop washing in the dock feels stingy. Best for multi-pet households on hard floors who value reliability and Matter smart-home integration over raw cleaning power.

Pros & Cons
What We Like
- + Dual rubber brush rollers handle pet hair better than any silicone alternative
- + PerfectEdge extending mop arm reaches corners and wall edges other robots miss
- + PrecisionVision AI recognizes pet waste, cords, and wet messes to avoid disasters
- + Matter-compatible for Apple Home, Google Home, and Alexa integration
- + AutoWash dock is genuinely hands-off with 75-day auto-empty capacity
What Could Be Better
- − 7,000Pa suction falls well short of competitors offering 12,000-20,000Pa at similar prices
- − Cold water mop washing only — no hot water cleaning like Roborock or Dreame docks
- − 120-minute battery life limits coverage to roughly 1,300 sq ft per charge
- − The extending mop arm occasionally drips water outside the cleaning path when retracting
