iRobot Roomba 415X vs iRobot Roomba 505X

Full Robot Vacuums comparison in 2026

Updated September 2026
Data from Amazon and official iRobot site.
2026 verdict
Unless Apple Home or Matter is a must, the iRobot Roomba 415X is the better pick of these two Roomba vacuum-and-mop robots.
It is rated for 200 minutes of runtime against 180, quotes 20,000 Pa of suction where iRobot publishes no figure for the 505X, is smaller and lighter at 84 mm tall and 6.44 lb, and usually costs less. The iRobot Roomba 505X wins on one thing, but it is a big one for some homes: it works with Apple Home, SmartThings, Home Assistant and Matter, where the 415X stops at Alexa and Google Home. Both use LiDAR, both AutoWash docks empty the bin and wash and dry the pads, and both lift the mop over rugs. Choose the iRobot Roomba 415X for most homes, and the iRobot Roomba 505X if Siri or a Matter controller has to run it.

What the differences mean

Smart home platforms

The iRobot Roomba 505X adds Apple Home, SmartThings, Home Assistant and Matter to the Alexa and Google Home both support. The iRobot Roomba 415X does not support Apple Home, SmartThings or Matter, and its Home Assistant support is not documented.

Battery life

The iRobot Roomba 415X is rated for 200 minutes, 20 minutes more than the 505X's 180. In a large home the 415X finishes where the 505X would stop to recharge and resume.

Size and weight

The iRobot Roomba 415X measures 298 x 303 x 84 mm and weighs 6.44 lb; the iRobot Roomba 505X is 358 x 351 x 107 mm and 9.44 lb. The smaller body fits under more beds and sofas and through tighter gaps between chair legs.

Suction

iRobot quotes 20,000 Pa for the Roomba 415X and no Pa figure for the 505X. The missing number is a gap in the spec sheet, not proof the 505X is weaker.

What owners say

Owners of both Roombas describe the AutoWash dock as the reason they bought one: the bin empties, the water refills and the pads are washed and dried with almost no hands-on work, and both groups report good pet-hair pickup on hard floors and carpet. iRobot Roomba 415X owners add that it is quiet enough for overnight runs and slim enough to reach under more furniture, and their complaints centre on an app that mislabels rooms after remapping and hair wrapping around the mop module. iRobot Roomba 505X owners single out the large water reservoir and accurate LiDAR maps, and warn that the cleaning cycle is loud enough to schedule for when nobody is home and that the first Wi-Fi pairing or map can need a retry.

Price history compared

Every price change of both, in the same store, so the gap between the two lines is what one costs more than the other.
