iRobot Roomba Plus 415X Review: A Slim Combo With a Real Wash Dock
Our verdict: 4.3 / 5
The 415X is the Roomba combo most families should look at first. It vacuums and mops in one run, lifts its spinning mops, scrubs harder on stuck messes, and its dock empties, washes, heat-dries and refills. It’s also much slimmer than the 405 it replaces. It doesn’t have a roller mop or heated-water washing, so very grimy kitchens are better served by the pricier 678X.

iRobot’s combo robots used to be a bit of a compromise. The vacuuming was good, the mopping was fine, and the dock didn’t do much for the mop pads. The Roomba Plus 415X is where that changes at a mid-range price. It has two spinning mop pads that lift off carpet, a SmartScrub mode that presses harder on dried messes, and an AutoWash dock that washes and heat-dries the pads after every run.
It’s also 46% slimmer than the Roomba Plus 405 it replaces, by iRobot’s numbers, which matters if your sofa sits low. This review covers what the 415X does well, where it’s limited and who should go up or down the range. We based it on iRobot’s published specs and design, not our own home testing.

What we like
Mops that come clean every time
The AutoWash dock washes the mop pads after every run and dries them with 113°F air. That stops the sour smell that builds up in damp pads and means each run starts with clean pads rather than yesterday’s grime. It also refills the robot’s water, so you’re not filling a tank every day.
SmartScrub for the dried-on stuff
Dried food, muddy paw prints and kitchen splatter are where light-touch robot mops fail. SmartScrub adds extra pressure where messes are stubborn. It’s still a pad, not a scrubbing brush, but extra downward force makes a real difference on footprints and light sticky spots.
Gets under more furniture
A slimmer body means it fits under more sofas, beds and cabinets. Dust collects most under furniture because nobody vacuums there by hand. Measure your lowest gap before buying, but the 415X will reach places its predecessor couldn’t.
Rubber brushes and edge reach
The tangle-free rubber brushes are a good match for pet hair, and the extending edge brushes pull debris out of corners. iRobot says you don’t need to pre-clean, thanks to LiDAR mapping with obstacle recognition for cords, shoes and toys. That’s a bold claim. We’d still pick up phone chargers before a run, as we explain in our guide on why robots get stuck.
Lifting mops for mixed floors
The mops lift on carpet, so you can run vacuum-and-mop on a whole floor with rugs. iRobot doesn’t list the lift height for this model, so for thick rugs we’d still set a no-mop zone to be safe.
What could be better
- Pads, not a roller. Spinning pads are fine for daily cleaning but don’t self-rinse while mopping like a roller does.
- Lift height not listed. Treat medium and thick rugs carefully until you’ve seen how it handles them.
- Unheated wash water. The dock heat-dries but doesn’t mention hot-water washing, unlike the 678X.
- Marketing numbers. “2.8x stronger” and “46% slimmer” are comparisons with iRobot’s own older models.
Who should buy it
- Families with mostly hard floor and some rugs
- Pet owners who want rubber brushes plus daily mopping
- Homes with low sofas and beds
- Anyone stepping up from a basic Roomba
Who should skip it
- Grease-heavy kitchens where a heated roller mop works better
- Mostly-carpet homes that don’t need mopping
- Tight budgets

| Roomba Plus 415X | Roomba Plus 678X | |
|---|---|---|
| Suction (maker) | 20,000 Pa | 30,000 Pa |

| Check price | Roomba Plus 415X | Roomba Plus 678X |
The 678X is the better mopper for messy kitchens. The 415X does most of the same daily work for considerably less money, and it’s the better value for typical homes.
Tips to get the most out of it
- Run the first map with doors open and floors clear, then name rooms in the app.
- Use SmartScrub in the kitchen and entry only. Elsewhere, a normal pass is enough.
- Empty the dirty-water tank every few days and let it air out.
- Set no-mop zones for thick or light-colored rugs until you trust the lift.
- Clean the rubber brushes every couple of weeks. See how often to clean the brush roll.
