iRobot Roomba Plus 415 Combo review

I haven't had this robot in my house. I'm working from iRobot's product page and the one published test I could read: Tom Shelton's three-month home test at Just a Dad Approved, last updated October 20, 2026. One person, one home. The 6.3 is my opinion of the two.

The money first. As of November 9, 2026, the 415 is $599.99£449€499 on iRobot's own store, where it's on sale. Check again on the day you buy.

It's the entry model of the Plus series, below the 515 and 575. iRobot launched it in summer 2026 alongside four other Roombas, per Vacuum Wars.

What iRobot says you get

A LiDAR robot that also mops. ClearView LiDAR maps the house, two DualClean pads spin at 200 RPM, and the AutoWash Dock promises up to 3 months of hands-free cleaning. The battery is a 5200 mAh NCM pack. The robot weighs 6.44 lb and measures 11.73 x 11.93 x 3.29 in.

iRobot also calls it 46% slimmer than the Roomba Plus 405 Combo. Read the footnote. That's by volume, so don't picture a robot that's half as tall.

What iRobot doesn't print bugs me more: no suction figure in Pa, no run time. A battery capacity doesn't tell you how many rooms you get per charge, and that's the number I'd want before spending $599.99£449€499.

What the one published test found

Shelton gave it 6.2/10 after three months. His sub-scores: mopping 6, carpet 6, hair tangle 5, obstacle avoidance 7.

The flaws are specific. Hair wrapped on the brush in his long-hair test. The small dustbin filled fast. It didn't reliably avoid cords and clutter on the floor. On the plus side, it got under low furniture well, which fits the 3.29 in height.

So the best thing about it is its shape. The rest lands around average.

If anyone at home has long hair

Skip it. A 5/10 for hair tangle means you'll be cutting hair off the brush, and the washing dock doesn't do that for you. Three months hands-free sounds less convincing when the brush needs a pair of scissors.

If your sofa and bed sit low

This is the case where I'd consider it. At 3.29 in, it's built to clean under furniture that taller robots bump into, and Shelton says it managed that in his home. Add a washing dock and you have a robot that mops under the couch without you rinsing pads.

Just pick up cables first. Shelton's test says it won't reliably do that dodging for you, even with a 7/10 for obstacles overall.

The 415 against the 105 Combo and the 515

The Roomba 105 Combo costs $299.99Not verifiedNot verified and comes with a self-emptying dock only, no washing dock. If you mostly vacuum and mop now and then, I'd save the difference and rinse pads by hand. The 415's extra cost buys you the AutoWash Dock and the slim body. Only pay it if both matter to you.

The Plus 515 Combo ($699.99£549€329) is the next step up. Whether that gap fixes the hair and dustbin complaints, Shelton's test of the 415 can't tell you.

What I'd do with my own money

Short-haired household, low furniture, mostly hard floors: I'd buy the 415 ($599.99£449€499) and keep the floor clear of cords. Long hair or a lot of carpet: I'd keep looking, because a 6/10 on carpet and a 5/10 on tangles are the two scores that would annoy me every week.
