A compact, low profile Roomba that mops with spinning pads and washes them in a hot water dock for well under its $699.99 list price. It suits smaller homes and low furniture. Skip it if you have long hair at home or lots of floor clutter, since a 3 month test found weak avoidance, hair wrap and Wi-Fi drops.
Best for: small homes with low sofas and beds. Skip if: you need strong obstacle avoidance or have long hair at home.

Just A Dad Approved lists dust bags and mop pads about every 2 months, the filter every 150 hours, side brushes every 200 hours and the main brush every 300 hours, and notes parts are sold by iRobot rather than on Amazon. We did not confirm US part prices on a fetched page, so no 3 year total is given.

What independent reviewers found
- 3 month real world test: subscores Hassle Free 6.7/10, Mop Performance 7.2/10, Carpet Cleaning 6.4/10, Hair Tangle 5/10, Obstacle Avoidance 7/10. Reported repeated Wi-Fi disconnects that needed hard reboots, hair wrap on the single brush roll, a slightly off map and a filter that can only be replaced. Says the Amazon only 515X is the same robot.
- Just A Dad Approved · 6.5/10
- Hands on with the Japanese model: measured 8.4 cm tall, cleaned under low sofas and cabinet toe kicks earlier Roombas missed, and avoided a camera placed as an obstacle. The review lists no drawbacks and carries affiliate links.
- Lifehacker Japan
- Reports 8.4 cm height against 10.6 cm for the 505 Combo, a front 120 degree line laser, and good cat and dog hair pickup with less long hair wrap. Figures come from iRobot's launch event, and the article is labeled PR.

Questions buyers ask
How is the Roomba Plus 515 Combo different from the 505 Combo?
The 515 is much slimmer at 3.29 in versus 4.2 in, and iRobot claims 3x the 505's suction. The 505 has a PrecisionVision AI camera for obstacles; the 515 uses a front line laser instead.
Should I get the 515 or the 575 Combo?
The 575 adds PrecisionVision AI obstacle recognition, a dock tank for cleaning solution and a 35 mm threshold rating for $799.99 at iRobot. Get the 575 if your floors are cluttered with cords and toys.
Is the Roomba 515X the same as the 515?
Just A Dad Approved says yes, the 515X is the same robot sold only on Amazon under its own model number.
Does it fit under low furniture?
The robot is 3.29 in tall per iRobot, so it fits under most furniture with about 3.5 in of clearance.
