iRobot Roomba Plus 515 Combo · Roborock Q5 Pro+

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.

A bag-only dock and no camera obstacle avoidance keep the price down, but the floor has to be picked up before a run, and no-go zones do the work a flagship’s camera would do while cleaning.

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.

Mixed carpet and hard-floor homes wanting one run to do both jobs

The mop pad attaches by hand, so a run that crosses from hard floor onto carpet means taking the pad off first or fencing the carpet with no-go zones. Vacuuming carpet on its own is well covered: 5,500 Pa and the all-rubber DuoRoller dual brush are built for hair and embedded debris.

Large homes or multi-zone multi-floor layouts requiring dock auto-refill

Q5 Pro+ dock is basic auto-empty only; does not auto-refill water or offer multi-level consumable management. Mop module requires manual water refill.

Owners requiring obstacle avoidance vision (glass tables, cables, transparent barriers)

The Q5 Pro+ maps and routes with PreciSense LiDAR but carries no camera obstacle avoidance, so cables, socks and pet messes are handled with no-go zones and a pre-run tidy rather than recognized on the fly. Transparent barriers and low clearances need setting in the app.
