## Verdict

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.

- Only 3.29 in tall
- Hot water pad wash and heated drying
- Pads lift 10 mm and extend to edges
- Up to 3 months between dock emptying
- Large discount off list price

## Cons

- No camera, weak obstacle avoidance in testing
- Long hair wraps the brush roll
- Wi-Fi drops and app freezes reported
- No cleaning solution tank in the dock
- Low 24 mm threshold climb

## Specs

- suction: iRobot US says 3x the suction of the Roomba Plus 505 Combo with four levels and gives no Pa figure; Just A Dad Approved lists 22,000 Pa; Lifehacker Japan instead says 3x the Roomba 105 Combo
- navigation: ClearView LiDAR, up to 3 saved maps for multiple floors, works in the dark (iRobot); Gizmodo Japan reports the LiDAR moved to the front as a 120 degree integrated line laser; Just A Dad Approved found the map slightly off
- obstacle avoidance: Front line laser recognizes cords, shoes, pet bowls, toys, pets and people (iRobot); no camera (Just A Dad Approved), which scored clutter 7/10 but called avoidance weak
- mopping: Yes, two DualClean spinning pads at 180 RPM that lift 10 mm on carpet, with PerfectEdge extension for 18% more edge coverage and a SmartScrub mode (iRobot)
- self empty: Yes, bagged auto empty into the dock; iRobot says up to 3 months hands free
- dock features: Empties debris, washes pads with hot water, dries pads at 113 F, refills clean water and takes in dirty water (iRobot). iRobot's page lists the wash as 167 F in one place and 140 F in another; Just A Dad Approved lists 140 F. No cleaning solution tank (Just A Dad Approved)
- runtime: Up to 295 min or 2,000 sq ft per charge with a 5,200 mAh battery (iRobot); one iRobot footnote cites 1,000 sq ft instead
- height: 3.29 in; robot is 11.73 x 11.93 in and 6.44 lb, 46% smaller by volume than the Roomba Plus 505 Combo (iRobot)
- pet hair: Single brush roll with a comb; Just A Dad Approved scored its hair tangle test 5/10 with long hair wrapping, while Gizmodo Japan saw cat and dog hair picked up well
- app: Roomba Home app with schedules; works with Alexa, Siri and Google Assistant (iRobot); Just A Dad Approved reported repeated Wi-Fi drops and app freezes

## 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.
