iRobot Roomba Plus 515 Combo · Yeedi M14 Plus

The dock takes over water, pads and debris for up to three months, but it stands far taller than the 3.29 in robot it serves and needs a fixed spot with power.

Suction is sold only as 3x the Plus 505, a relative claim with no pascal figure on iRobot’s own page.

The sensors that make obstacle recognition work are a camera and a light in your home: the M14 Plus carries a camera, an LED illuminator and a 3D structured light projector alongside its dToF lidar, and the LED lights the room so the camera can see during runs in the dark.

The station does the mop maintenance, and it is a lot of machine to own: washing the OZMO Roller in 167 F water and hot-air drying it after every run removes the pad chores entirely, at the cost of a station with a water heater, two tanks to fill and empty by hand, and a disposable bag to replace.

Large homes beyond 2,000 square feet per run

iRobot rates coverage at 2,000 sq ft per charge and has not documented recharge-and-resume behavior for larger floor plans on this model.

Deep or high-pile carpet

Pads lift only 10 mm on carpet detection, and no independent carpet test of this model has been published to show how it handles dense pile.

Buyers who want detergent dosed automatically

The dock does not add cleaning solution itself; iRobot directs owners to add a compatible solution to the tank by hand.

Buyers waiting for independent performance testing

Launch coverage from Vacuum Wars and Reviewed contains no test results, so every suction, runtime and coverage figure today is iRobot's own.

Homes where a camera-equipped robot is not wanted

Obstacle recognition on the M14 Plus works from a camera, an LED illuminator and a 3D structured light projector alongside the lidar. The LED lights the room so the camera can see during runs in the dark.

Owners expecting a plumbed-in station

The OMNI Station is filled and emptied by hand. It washes the OZMO Roller from its own clean water tank and collects the used water in a dirty tank, and it empties the robot into a 3 L disposable bag that is replaced rather than emptied.

Multi-floor homes where carrying the robot is impractical

Maps for several floors are stored, but the station lives on one level and the robot has to be carried to the others and back to dock, empty and wash.
