The cheapest way into a LiDAR Roomba with an auto empty dock, and RTINGS picked the Roomba 105 as its best cheap robot vacuum. Vacuum Wars found good carpet deep cleaning but very weak pet hair pickup and heavy hair wrap. Pet owners should look at the Dreame D20 Plus or Roborock Q7 M5+ instead.

A capable 2026 Roomba with LiDAR, a roller mop and a hot wash dock that needs attention only about every 90 days, and at $799.99 it now sits in the midrange. Reviewers split: Gizmodo and Xataka liked its vacuuming and mopping, while Tom's Guide found it loud, prone to scattering debris and leaving mop residue. Skip it if you need it to fit under low furniture or want the quietest robot.

What reviewers found

iRobot Roomba 105 Vac + AutoEmpty Dock

  • Vacuum Wars (1.41 Vacuum Wars stars): Removed 82% of embedded sand, above the 75% average, but picked up only 29% of flattened pet hair and 79% of long hair wrapped the brush. Coverage was about 630 sq ft per charge and it has no obstacle avoidance. Source
  • RTINGS: Named the Roomba 105 its best cheap robot vacuum for smart navigation, long battery life and an optional self empty dock, but called vacuuming only adequate and obstacle avoidance weak. Source

iRobot Roomba Max 775 Combo

  • Gizmodo: Good vacuuming with no clogs and a streak free roller mop that handled ketchup about as well as rivals, but noisy, a buggy app on long runs, unreliable carpet detection and trapped twice under a bed. A full vacuum and mop of 750 sq ft took about 2.5 hours. Source
  • Tom's Guide: Hard to recommend. Hardwood pickup of 44% hair, 86.5% Rice Krispies and 91% chia seeds; carpet 52%, 63.5% and 35%. Bumped walls often, scattered debris with its side brushes and left slight mop residue. Source
  • Xataka: Excellent pet hair pickup and effective hot water roller mopping; cleaned 55 m² in 40 minutes using 33% of the battery. Fixed side brushes made corners less thorough and bags and solution are costly. Source
