iRobot Roomba Plus 515 Combo review

a good mop with a long-hair problem

In Just a Dad Approved's three-month test, the Roomba Plus 515 Combo mops well and does poorly with long hair. I'd buy it for a home with mostly hard floors and nobody with long hair.

I haven't used this robot. Everything here comes from iRobot's product page, which I read on November 7, 2026, and from one test: Tom Shelton's three-month review at Just a Dad Approved, last updated October 20, 2026.

That's the whole file. My 6.3 is an opinion built on one tester's results and a spec page. It could move once a bigger outlet tests one.

The money: as of November 7, 2026, iRobot's US price is $699.99£549€329.

Where it sits in the line-up

Vacuum Wars reports it launched in summer 2026 alongside four other Roombas. It's the middle of the Plus series. The 415 ($599.99£449€499) sits below it, and the 575 (Not verified) sits above.

The line that matters is between the 515 and the 575. Both the 515 and the 415 navigate with ClearView LiDAR and have no PrecisionVision AI. The 575 adds that AI obstacle recognition. My sources don't say exactly what the 515 adds over the 415, so put the two iRobot pages side by side before you pay the difference.

The mop is the good part

The DualClean pads spin at 180 RPM, per iRobot. Shelton found the internal water tank keeps the pads wet through a whole run, and mopping got 7.2/10, his highest sub-score.

The dock self-empties for up to 3 months, iRobot says, and it washes the pads with hot water and dries them at 113 °F (45 °C). The wash temperature is where it gets odd. One section of iRobot's page says 140 °F (60 °C). Another says 167 °F (75 °C). I can't tell you which is right, and iRobot should fix that.

Long hair is the dumb problem

Shelton scored hair tangle at 5/10. Long hair wrapped around the single-piece brush roll. Carpet cleaning came in at 6.4/10.

This annoys me, because the suction claim gives me nothing to check it against. iRobot says 3x the suction of earlier Roombas and prints no Pa figure. It doesn't print a run time either, only a 5200 mAh battery. Three times what, exactly?

If anyone in your house has long hair, plan on cutting it off the roller by hand. I'd skip the 515 in that house.

Obstacles without a camera

Obstacle avoidance got 7/10 from Shelton. That's a fair result for a robot with no AI recognition, and it makes me less inclined to push you up to the 575. If your floors are usually clear, I'd keep the money. If cables and socks live down there, the 575's camera is the reason to pay more. I haven't seen a test of the 575 to confirm it does better.

Wi-Fi drops

Shelton reports Wi-Fi disconnects. His fix was holding the power button for 10 to 15 seconds. He's one tester with one unit, so I can't tell you how common this is. Still, nobody wants to reset a vacuum by hand to get it back online.

About the scores

Shelton's overall score is 6.5/10. I land at 6.3: the hair result and the missing numbers on iRobot's page pull me under his figure.

Who I'd sell it to

Mostly hard floors, short hair, and you want the mopping and pad washing handled for you: I'd buy it. The 7.2 mop score is the reason.

Lots of rugs, or long hair: skip it. If you don't care about mopping, the Roomba Max 715 Vac ($699.99£329€379) is in the same list-price band. It only vacuums, and it has obstacle AI. PCWorld found it strong on rugs.
