Roomba Plus 415 Combo
iRobot's cheapest slim vacuum and mop, 8.35cm tall, with a compact dock that empties, washes and dries the pads. It cleans edges well, but it can't see clutter and hair still wraps the brush.
See the alternatives below, or switch market.
The short version
The Plus 415 Combo is the entry model in iRobot's slim 2026 Roomba Plus range, below the Plus 515 and Plus 575. It's 8.35cm tall, so it gets under more furniture than most, and it vacuums and mops in one run with two spinning pads that lift 10mm on rugs. The dock empties the bin into a bag and washes the pads, then dries them with warm air. It replaces the taller Plus 405 Combo. The 415X sold on Amazon is the same robot.
The savings show in what's missing. There's no camera, so cables, toys and socks get treated as floor, and there's no water tank on the robot or detergent dosing in the dock. The small body also means a small bin and battery, so it's built for flats and smaller homes. One tester found no official replacement parts on sale three months after launch.
Our take: Buy it for a small flat with mostly hard floors and low furniture, if you're disciplined about picking things up before it runs. It mops edges well and the dock is small enough to find room for. If your floors are cluttered, the Plus 575 Combo adds a camera. For pet hair or mostly carpet, the eufy Omni E25 is a stronger cleaner, though taller.
Where it sits in iRobot’s range
What reviewers found
Two home tests. Ideal Home ran it in a one-bedroom flat with laminate, vinyl, rugs and a cat, and Just A Dad Approved lived with it for three months. Both praise the edge cleaning and the slim body, and both found obstacle avoidance poor and hair wrapping the brush. They disagree on mopping: Ideal Home calls it one of the best at this price, while Just A Dad Approved found it light and had pads fall off mid-run.
Ideal Home, hands-on, Aug 2026 (Tested in a one-bedroom flat with a cat) · Just A Dad Approved, hands-on, Three months, Sept 2026
Can't see what's on the floor
Both testers agree this is the big weakness. Ideal Home calls its object avoidance the worst it tested this year: it dragged cat toys into the hallway, tangled in charging cables almost at once, tried to climb a pet feeder and ran into her feet. Just A Dad Approved found it didn't reliably dodge cords or small clutter. iRobot says it steers round cords, shoes and toys, but it has no camera. Clear the floor before every run.
Edges and corners come up clean
This is its best trick. Ideal Home found the pads and side brush got right up against skirting boards and cleaned a permanently grubby corner by a cat flap. Just A Dad Approved also rates its corner and wall cleaning highly, and found room navigation strong without a turret on top. Mapping was quick and accurate for Ideal Home. If dust lines along the walls annoy you, it does that job well.
Mopping splits the testers
Ideal Home was impressed: a fresh barbecue-sauce spill on laminate came up in one pass, scrubbed rather than smeared, with nothing carried onto a nearby rug, and it called the mopping one of the best at this price. Just A Dad Approved found it light-duty, blaming the lack of a water tank on the robot, cold-water pad washing and pads that sometimes fell off. Fresh spills should be fine; don't expect deep cleaning of old marks.
Hair still wraps the brush
iRobot sells the rubber brush as tangle-free, but neither tester agrees. Ideal Home saw three tufts of hair go up in one pass, then found every strand wrapped tightly round the roller afterwards. Just A Dad Approved also saw wrap, rated pet-hair pickup only okay, and found the small bin filled quickly, after which the robot keeps running without picking much up. Owners with shedding pets should expect regular scissor work.
Small dock, small robot, few parts
The dock is compact: Ideal Home found it about half the floor space of a MOVA P50 Pro Ultra and fitted it in a small flat easily, though assembly felt flimsy and there's nowhere to add detergent. Just A Dad Approved says the small battery, bin and pads suit small homes, and that it will struggle in a larger one. Three months in, he still couldn't buy official replacement parts, only third-party ones.
The Plus 415 and Plus 415X are the same robot and dock; the X is the Amazon model number.

Before you buy
The questions people ask about this one
Will it avoid cables and pet mess?
No. Ideal Home found it tangled in charging cables and dragged cat toys around, and Just A Dad Approved saw it miss cords and small clutter. It navigates by laser alone, with no camera, per the specifications. Pick things up first.
Does it fit under low furniture?
Very likely. It's 8.35cm tall and about 30cm across, per the specifications, and Just A Dad Approved found the slim body got under furniture that stops bigger robots. That's much lower than the Plus 405 Combo it replaces.
Can it leave the mops in the dock for carpet?
No, but it lifts the pads 10mm when it detects carpet, per the specifications. Ideal Home heard the suction rise as it crossed rugs and found nothing damp the next morning. Deep-pile rugs are the risk, so test yours.
How big is the dock, and is it loud?
It's 33 × 33 × 48.5cm, per the specifications, and Ideal Home found it about half the floor space of a rival's washing dock. Neither tester measured the noise. The dock empties into a bag and dries the pads with warm air after washing.
How often do I have to empty or refill anything?
iRobot claims up to three months between bag changes, per the specifications. You'll refill the dock's clean-water tank and empty the dirty one. Just A Dad Approved found the robot's small bin filled fast in a home with pet hair, and Ideal Home says filters need changing every three to six months.
Compare with
Roomba Plus 575 Combo
The same slim body with a camera for clutter and a dock that hot-washes the pads and doses detergent.
One tester hit repeated Wi-Fi dropouts.
Omni E25
One of the best robots tested for pet hair, with a camera for cables and shoes.
It's 11.2cm tall and can't keep its wet roller off deeper carpet.
P50 Pro Ultra
A hair-cutting brush, a hotter mop wash and mops it can leave in the dock.
Its dock takes up far more floor, and lab tests disagree about carpet.
