All robot vacuums. Every figure below is placed against the whole class, so a gap can be read against how much the class itself varies.
Where each one suits you.
The conditions each robot was assessed against, side by side. Rows marked in gold are where these machines genuinely differ.
| Condition | Deebot X9 Pro Omni | Roomba Plus 515 Combo |
|---|---|---|
| Home size | ||
| Under 1,500 sqft | GoodSingle-session runtime covers under 1500 sqft; efficient bin-emptying interval for compact homes. | GoodA 295-minute, 2,000 sq ft rating per charge covers a home this size in one run. |
| 1,500 – 3,000 | GoodTarget size range. Multi-floor mapping supports two-level homes; single-session scheduling typical. | GoodiRobot rates a charge at 2,000 sq ft, covering most homes in this range in one run. |
| Over 3,000 | DependsExceeds single-session battery range. Multi-run scheduling required; adds overall cycle duration. | DependsRated 2,000 sq ft per charge, and recharge-and-resume behavior is not documented for this model. |
| Primary floors | ||
| Hard floors | GoodDual rollers and suction calibrated for hard surfaces. Mop wash cycles optimized for tile and laminate. | GoodSpinning DualClean pads at 180 RPM with SmartScrub target dried spills on sealed hard floors. |
| Low / medium pile | GoodLow-pile carpet is primary design target. Dual-roller traction ensures consistent coverage. | GoodCarpet detection lifts the pads 10 mm before crossing rugs, per iRobot. |
| High pile / shagthey differ | PoorOwner reports document suction loss and roller slippage on high-pile and shag. Not recommended for carpet-exclusive homes. | DependsA 10 mm pad lift may not clear dense pile, and no independent carpet test exists for this model. |
| Mopping needs | ||
| Vacuum only | GoodStrong vacuum; the mop lifts or detaches when not needed. | GoodStrong vacuum; the mop lifts or detaches when not needed. |
| Light mopping | GoodActive mopping system covers routine floors easily. | GoodActive mopping system covers routine floors easily. |
| Frequent mopping | GoodPressure or rotating mop with self-wash is built for frequent mopping. | GoodPressure or rotating mop with self-wash is built for frequent mopping. |
| You want to… | ||
| Empty bin myself | GoodWeekly mop-pad swaps and monthly filter changes align with hands-on ownership profile. | GoodHands-on upkeep is light; the dock handles debris, water and pad washing. |
| Empty occasionally | GoodDock automation (heating, water service) reduces overall effort; manual tasks (pad swaps, tank refills) remain weekly. | GoodOwner tasks come down to brush checks, adding solution and a tank service every few months. |
| Set-and-forgetthey differ | DependsMop system requires weekly manual intervention. True hands-off operation unavailable on Omni platform; consider self-wash + auto-dry docks for zero-touch mop service. | GoodiRobot rates the dock for up to three months without emptying bins or handling water. |
A robot being poor for a condition is a fact about fit, not a fault. “Depends” means the record names a limit worth reading, not that the answer is unknown.
How far apart is a long way?
A number only means something next to the spread it sits in. Each track is the real range across every classified robot in the class, with the median marked.

Not compared, because fewer than two of these robots carry a published figure: Suction, Charge time, Noise, Weight.
What the numbers leave out.
Written on each record, and the only thing here every robot on the site carries.
The trade-off
What each design gives up to be good at what it is good at.
Ecovacs Deebot X9 Pro Omni
The station carries the mop routine and asks for space and refills in return: it heats its own wash water, dries with 145F air and doses detergent, while its clean and dirty tanks are filled and emptied by hand from a fixed floor position.
iRobot Roomba Plus 515 Combo
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.
Who each one is wrong for
Stated by the record itself. A robot being wrong for a household is a fact about fit, not a fault.
Ecovacs Deebot X9 Pro Omni
- High-pile carpet exclusive households
- Mopping is the reason for the roller, the heated wash station, the detergent system and the water tanks, and on carpet the Triple Lift System raises the roller clear so the carpet stays dry. In a carpet-dominant home that hardware, and most of the price, goes unused. Sweeping is a single main brush in a floating housing plus one side brush, rated at 16,600 Pa.
- Fully hands-off operation seekers
- The station covers wash, dry, detergent and dust on its own, but its clean and dirty water tanks are filled and emptied by hand and it holds a fixed floor position near an outlet. Stations with a plumbed water-line kit are what remove that last step.
- Buyers working to a lower budget
- MSRP is $1599, and most of that is the station: 40 to 75C water washing, 145F drying, detergent dosing and auto-emptying into a 3 L bag. A robot with a plain charging base sweeps the same floors for a fraction of it and moves the mop service back to the owner.
iRobot Roomba Plus 515 Combo
- 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.
What stays your job
The upkeep ownership hands back to you, whatever the autonomy level says.
Ecovacs Deebot X9 Pro Omni
- After every run: No owner task. The station washes the mop roller in water it heats to between 104 and 167F, adjusted by room and soil level, then dries it with 145F air on a two, three or four hour cycle, and empties the dust bin into the bag.
- Weekly: Refill the station’s clean water tank, empty its dirty water tank, and check the detergent reservoir.
- Monthly: Check the main brush and side brush for wound hair; wipe the robot’s sensors and the station tray.
- Up to every 90 days: Replace the station’s 3 L debris bag, the interval Ecovacs rates it at.
- Every 3-6 months: Clean or replace the robot’s filter and inspect the mop roller for wear.
iRobot Roomba Plus 515 Combo
- Every 3-6 months: Empty the dock’s debris storage and dirty-water tank, and refill clean water, per iRobot’s up-to-three-month rating.
- As needed: Add a compatible cleaning solution to the tank by hand; the dock does not dose it.
- Weekly: Check the rubber and bristle main brush and side brush for hair.
- Monthly: Wipe the LiDAR window, cliff sensors and charging contacts.
- As needed: Replace DualClean pads, filters and brushes from iRobot’s Plus 515 accessory series as they wear.
How much each of these is standing on.
Classifications rest on different depths of evidence. A pre-release assessment and a verified one are not the same kind of claim.

Evidence status counts the sources behind a classification, not their kind. A high count can be maker documentation and price coverage, so read it as how much was reviewed rather than as independent testing. How we weigh evidence.
