About this model

The Combo in the name of the iRobot Roomba Combo j5+ promises more than Vacuum Wars could measure: its mopping mark is 0.21 on a five-point scale, when half the robots that lab has tested reach 2.58 or more. The reasons lie in how the mop works. It is a separate bin with a pad, filled and swapped in by hand as Tom's Guide noted, it presses on the floor with no added force, and it cannot lift. Carpet has to be fenced off in the app, because the robot does not recognize it while mopping, and Vacuum Wars adds that the wet bin has no drip tray and must come out when the run ends. Mopping is a light wipe the owner sets up, not something the robot does unasked.

What testers say about the iRobot Roomba Combo j5+

The Combo in the name of the iRobot Roomba Combo j5+ promises more than Vacuum Wars could measure: its mopping mark is 0.21 on a five-point scale, when half the robots that lab has tested reach 2.58 or more. The reasons lie in how the mop works. It is a separate bin with a pad, filled and swapped in by hand as Tom's Guide noted, it presses on the floor with no added force, and it cannot lift. Carpet has to be fenced off in the app, because the robot does not recognize it while mopping, and Vacuum Wars adds that the wet bin has no drip tray and must come out when the run ends. Mopping is a light wipe the owner sets up, not something the robot does unasked.

As a vacuum it stands firmer. Vacuum Wars placed its vacuuming just under the lab's median and found it drew more sand out of carpet than most Roombas it had tested, with few tangles. Its camera took it around 9 of 12 obstacles, above the average there, and Tom's Guide saw it avoid fake pet mess every time.

Pros

Cons

Where the testers disagree

  • Carpet: Vacuum Wars: Deep cleans carpet better than most Roombas tested · TechRadar: Does a consistently good job on rugs against Vacuum Wars: Does not detect carpet in mop mode, so you set no-mop zones
  • Pet hair: Vacuum Wars: Picks up hair easily with few tangles on its rollers · TechRadar: Clears cat hair from carpet and hard floor without clogging against Tom's Guide: Brush scatters pet hair instead of collecting all of it
  • Obstacles: Vacuum Wars: Camera steers it around toys, cords and pet mess · Tom's Guide: Spotted and steered around fake pet mess every time against TechRadar: Misses smaller items like curtains and little toys
  • Pickup: Tom's Guide: Keeps making passes until cereal is cleared from hard floors against TechRadar: Struggles with fine dust such as flour on hard floors
