Quick Answer: The Roomba Plus 505 Combo ($999.99 list, now commonly $499–$599, model N185020) is the best-reviewed Roomba iRobot currently sells — Tom’s Guide calls it “the best Roomba overall,” and aggregator Criticaster puts it at 82/100 across expert reviews. ClearView Pro LiDAR pairs with PrecisionVision AI, a front-facing camera that steers around cords, socks, shoes, and pet waste — a feature the cheaper Plus 405 lacks entirely. Extending DualClean mop pads with Carpet Boost and a heated-dry AutoWash dock round out the package. The trade-offs: Trusted Reviews measured it as genuinely loud on max suction and during auto-empty, and its app drew complaints for a clunky, hard-to-navigate interface.
iRobot’s last two Roomba launches this year didn’t go especially well. The Plus 405 shipped LiDAR to close the navigation gap against Roborock and Dreame, then tested at a bottom-of-the-field 1.85 out of 5 on Vacuum Wars’ independent rig. The Max 705 fixed navigation too, but reviewers kept flagging weak pet-hair pickup as the recurring complaint. The Roomba Plus 505 is the version of this generation that actually landed — it’s the one currently topping “best Roomba” lists instead of showing up in cautionary reviews.
What makes the Plus 505 different
The headline feature is PrecisionVision AI, a forward-facing camera paired with the robot’s ClearView Pro LiDAR. Most budget and mid-tier robots navigate with LiDAR or a camera, not both working together for obstacle avoidance specifically — LiDAR alone is good at mapping a room but can still steer straight into a phone charger cable or a sock on the floor. PrecisionVision AI is built to recognize and route around exactly those objects, plus pet waste, which iRobot calls out by name given how common a complaint that is across the whole robot-vacuum category.
On mopping, the DualClean pads extend sideways along baseboards for what iRobot brands PerfectEdge coverage, and a Carpet Boost mode automatically raises suction the moment the robot senses it has rolled onto a rug — the kind of feature that matters because the Plus 405 mopped well on hard floors but had no meaningful carpet-cleaning story in the same package. The AutoWash dock empties the dustbin, refills the mop’s water tank, auto-dispenses cleaning solution, and — the detail that separates it from the 405’s dock — heat-dries the mop pads after washing instead of leaving them to air-dry, which cuts down on the musty-mop smell that’s a common complaint on cheaper docks.
How it actually performs
Tom’s Guide’s hands-on review is blunt about the result: the reviewer says they’re “never going back to my regular stick” vacuum after testing it, citing the robot reaching deep into corners, scrubbing floors clean, mapping the house fast, and handling pet hair well. That combination — real edge-cleaning plus real pet-hair pickup — is exactly where the Plus 405 struggled; Vacuum Wars measured the 405 at the lowest flattened pet-hair score it had recorded, so a Roomba that handles pet hair credibly is a meaningful step up within iRobot’s own catalog.
Two review aggregators back up the hands-on take: Criticaster lists the Plus 505 at 82/100 based on expert reviews focused on the vacuum-and-mop combo, and a broader tally across more outlets still lands at 79/100 — solidly above where iRobot’s other 2026 launches have scored. Tom’s Guide goes further, naming it outright as “the best Roomba overall” in its current Roomba buying guide.
Roomba Plus 505 Combo + AutoWash Dock
- ClearView Pro LiDAR + PrecisionVision AI camera avoid cords, socks, shoes, and pet waste.
- Extending DualClean mop pads with Carpet Boost and a heat-drying AutoWash dock.
- 7,000 Pa rated suction — a real published spec, not a marketing ratio.

Where it still falls short
Reviews that praise the cleaning are consistently less kind about two things: noise and software. Trusted Reviews measured it directly and didn’t hedge — “on the highest vacuum setting it is very loud, and the auto-empty cycle at the dock is particularly intrusive.” That tracks with a pattern across iRobot’s whole 2026 lineup: the Plus 405’s dock measured 87.8 dBA during auto-empty, among the loudest tested.
The app is the other recurring complaint. New Atlas called it “a tad shambolic,” and Trusted Reviews was more specific: a complicated interface, difficult room labeling, no simple list view, and limited options for partial map updates. Tom’s Guide separately flagged the app as “sometimes glitchy” and noted Spot Clean mode underperforms. None of these are cleaning-performance issues, but they’re the kind of daily-friction complaints that show up repeatedly enough across independent outlets to trust.
One more physical nitpick from Trusted Reviews: the beater brush has fixed ends, making tangled hair and debris more cumbersome to clear than on brushes designed to pop out for cleaning — worth knowing if you’re shopping this specifically for a heavy-shedding household.

What we like
- Best-reviewed current Roomba. 82/100 on Criticaster, “the best Roomba overall” per Tom’s Guide.
- Real obstacle-avoidance camera. PrecisionVision AI plus LiDAR — a combination the cheaper Plus 405 doesn’t offer.
- Genuine carpet story. Carpet Boost auto-raises suction on rugs, addressing a gap in the 405’s mostly hard-floor-focused package.
- Heated mop-pad drying. Cuts down on the musty-dock smell common with air-dry-only systems.
- Published suction spec. 7,000 Pa — a real number, unlike the 405’s marketing-only “70x” claim.
What we don’t like
- Loud in daily use. Trusted Reviews measured it as very loud at max suction, with an especially intrusive auto-empty cycle.
- App usability complaints across multiple outlets. Complicated interface, weak room labeling, no list view, limited partial-map editing.
- Fixed-end beater brush makes hair removal more fiddly than pop-out designs.
- Spot Clean underperforms, per Tom’s Guide.
How it compares
Within iRobot’s own 2026 lineup, the Plus 505 is the clear standout. The Roomba Plus 405 is cheaper but tested at the bottom of Vacuum Wars’ field — a 1.85/5 score driven by the lowest pet-hair pickup the site had recorded and a mop that left roughly 5x more water behind than average. The Roomba Max 705 pushes harder on pure hard-floor mopping with its PowerSpin roller, but costs meaningfully more and shares the same pet-hair weakness that’s dogged this generation. The Plus 505 is the one iRobot 2026 launch where independent reviewers and hands-on testers largely agree the hardware, navigation, and cleaning results actually hang together.
Against the wider market, the Roomba vs Roborock comparison covers how iRobot’s approach stacks up against the current LiDAR leader, and our best robot vacuum for pet hair and best robot vacuum and mop rankings show where the Plus 505 lands against non-iRobot competition.
Who should buy the Roomba Plus 505
- Buy it if you want iRobot’s most well-rounded 2026 Roomba — real obstacle avoidance, genuine carpet cleaning, and credible pet-hair pickup in one package.
- Buy it if you’ve been burned by a robot that eats cords or socks; PrecisionVision AI is built specifically for that failure mode.
- Buy it if a heated-dry mop dock and edge-reaching mop pads matter more to you than saving $100–$200 on the Plus 405.
- Skip it if dock noise during auto-empty would bother you or household members — it’s a measured, repeated complaint, not a one-off.
- Skip it if you want the simplest possible app experience; look at the best robot vacuum rankings for easier-to-use alternatives.
The bottom line
The Roomba Plus 505 is the 2026 Roomba that actually delivers on what the Plus 405 and Max 705 promised: real obstacle avoidance via PrecisionVision AI, genuine carpet performance via Carpet Boost, and pet-hair pickup that hands-on reviewers actually praise instead of flagging as a weak point. Tom’s Guide calling it “the best Roomba overall” and an 82/100 aggregate score back that up. It’s not silent — auto-empty is a known loud point — and the app still needs work. But of iRobot’s three current 2026 releases, this is the one worth the closest look.
