It vacuums and mops, lifts its pads over carpet, and returns to an AutoWash dock that empties the bin and washes and dries the mops, it runs up to 180 minutes against 120, and it works with Apple Home, SmartThings, Home Assistant and Matter on top of Alexa and Google Home. The iRobot Roomba 205 is the lower priced, vacuum-only alternative: no mop and no dock tower, just a small charging base and a DustCompactor that presses debris inside the robot so the bin fills slowly. Both share LiDAR mapping, 7000Pa of suction, dual-band Wi-Fi and a child lock. Pick the iRobot Roomba Plus 505 for a fully automated vacuum and mop routine, and the iRobot Roomba 205 when you only need vacuuming and space for a dock is tight.

What the differences mean

Mopping

The iRobot Roomba Plus 505 mops as it vacuums, lifts the pads over rugs, and its dock washes and dries them. The iRobot Roomba 205 is vacuum-only.

Emptying

The iRobot Roomba Plus 505 empties into its dock after runs. The iRobot Roomba 205 has no self-emptying dock; it compacts debris inside the robot so you empty it less often, but by hand.

Battery

180 minutes against 120. In a larger single-level home the iRobot Roomba 205 is more likely to stop and recharge before it finishes, something its owners mention often.

Smart home

Both work with Alexa and Google Home. The iRobot Roomba Plus 505 adds Apple Home, SmartThings, Home Assistant and Matter.

Space

The iRobot Roomba Plus 505 dock measures 450 x 344 x 470 mm, a real piece of furniture. The iRobot Roomba 205 only needs a small charging base.

Which one to buy if

What owners say

Owners of both Roombas praise LiDAR mapping that builds an accurate map quickly and strong pet hair pickup on hard floors and carpet. iRobot Roomba Plus 505 owners single out the AutoWash dock returning mid-run to rinse the mops and then emptying and drying everything, and they warn that the unit and its self-cleaning cycle are louder than expected, that some saw bumper or docking errors after a few months, and that buying from an authorized seller matters for warranty help. iRobot Roomba 205 owners like how rarely the compacted bin needs emptying and how small the base is, and their main complaint is battery life, with a single level sometimes needing two or more recharges.

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.
