Reviews last updated: July 2026 · How we calculate this

What customers like about iRobot Roomba 671

  • Easy to use via the smartphone app
  • Good price-to-quality ratio
  • Can easily drive over small thresholds
  • Effectively captures dust and pet hair
  • Saves a lot of time and helps automate household chores
  • Attractive design with readily available parts

What customers don't like about iRobot Roomba 671

  • Makes relatively loud noise while vacuuming
  • Sometimes struggles to detect black/dark objects via sensors
  • Misses corners, gaps, and edges in rooms occasionally
  • Lacks intelligent navigation, causing random movement that may miss spots or repeatedly clean the same area
  • May sometimes fail to return automatically to the charging station
  • Can leave minor scratches or scuff marks on white skirting boards or furniture due to non-plush bumpers

Verdict

The iRobot Roomba 671 is an entry-level robot vacuum featuring an 1800 mAh lithium-ion battery that delivers up to 90 minutes of runtime, a 350 ml AeroVac dustbin capacity, and a 3.5-inch low-profile chassis designed to clear low furniture. Its core performance is driven by a patented 3-Stage Cleaning System that pairs dual multi-surface brushes with an edge-sweeping brush, alongside specialized Dirt Detect sensors to automatically intensify suction on heavily soiled areas. Key pros include seamless integration with the iRobot Home app for automated scheduling, compatibility with Amazon Alexa and Google Assistant voice controls, and an auto-adjusting cleaning head suitable for both low-pile carpets and hard floors. However, major cons include its reliance on random, non-methodical navigation that can miss spots, a lack of recharge-and-resume capability, a high tendency for hair to tangle in the bristle brushes, and frequent struggles with wires, tassels, or thick shag rugs.
