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.

5.6/10Price tracked daily

A space saving Roomba with no tall dock, good LiDAR navigation and a large compacting bin. TechRadar needed to empty it after 8 days rather than 60 and measured 78 dB. Mopping and obstacle handling are weak, so it suits small tidy homes.

iRobot Roomba 205 DustCompactor Combo

  • TechRadar (Performance 2.5/5): Measured an average of 78 dB from five feet. The roughly 1.5 L bin needed emptying after eight days. It pushed aside toys and dragged a phone cable. Called a crushing disappointment. Source
  • Tech Advisor: Good carpet cleaning and LiDAR navigation, but mopping mostly spread mess and it got stuck on furniture bases and thin table legs. Source
