iRobot Roomba Plus 505 Review: Fast LiDAR Mapping Meets a Self-Washing Mop
Quick, accurate room mapping and a dock that washes and dries its own mop pads, offset by real noise and occasional navigation hiccups some owners report.
The Roomba Plus 505 combines LiDAR-based mapping with a vacuum-and-mop combo and an AutoWash dock that empties its bin and washes and dries its own mop pads. Owners frequently praise how quickly it builds an accurate map, how well it handles pet hair and mixed hard floors and carpet, and how much manual upkeep the dock removes, while a meaningful share of reviewers report the unit runs louder than expected and some describe navigation or mechanical issues emerging after a few months of use. For buyers who want a genuinely automated vacuum-and-mop routine and are comfortable buying from an authorized seller for warranty protection, it's a compelling middle-tier pick in iRobot's lineup.

Who is the Roomba Plus 505 for?
The Plus 505 suits buyers who want a full vacuum-and-mop routine automated end to end. Its Laser (LiDAR) navigation with PrecisionVision AI obstacle avoidance supports multi-room mapping and no-go zones, and the DualClean spinning mop pads with SmartScrub handle daily mopping on hard floors. With up to 120 minutes of runtime, auto-recharge, and a self-emptying AutoWash dock that also washes and dries the mop pads, it's built for households that want to hand off floor care almost entirely, especially those with pets and a mix of carpet and hard flooring.
What buyers love
Reviewers consistently highlight how fast and accurate the LiDAR mapping is, often building a usable map of a full floor in well under an hour on the first run. Pet owners specifically call out strong pickup of pet hair even in multi-cat and multi-dog households, and several note the vacuum and mop can run together or separately depending on the schedule, matching the mopping and carpet-cleaning support confirmed in the spec sheet. The AutoWash dock coming back mid-cycle to rinse the mop pads, then emptying and drying everything at the end of a run, is repeatedly named as the standout convenience feature.
What to know before you buy
Noise is the most common caveat: multiple owners describe the unit as noticeably louder than expected, especially while docked and processing its self-cleaning cycle, similar to a washing machine running nearby. A handful of reviewers also report navigation issues surfacing a few months in, such as recurring bumper-stuck errors or trouble finding the dock, and at least one buyer found the roller design on this model traps hair more than expected. Several reviewers stress buying only from iRobot or an authorized retailer, since a couple of owners who bought through third-party sellers had trouble getting warranty support for mechanical failures.
Is the Roomba Plus 505 worth it?
For buyers who want fast, accurate mapping and a mop that essentially maintains itself, the Plus 505 delivers real day-to-day time savings, most reviewers describe it as a meaningful upgrade over older robot vacuums. The trade-offs are the audible noise during self-cleaning cycles and a minority of owners hitting navigation or durability issues after the first few months, so buying from an authorized seller for warranty coverage is worth the extra care. Overall it's a solid choice for anyone prioritizing hands-off vacuum-and-mop convenience over whisper-quiet operation.
