A robot vacuum purchase is really two purchases: the robot that drives around and the dock it returns to. The same robot name can ship with a plain charger or with a station that empties the bin, washes and dries the mop and refills water. Decide which chores you want to hand over before comparing suction numbers or sensor names.
Decide which dock chores you want automated
Write down the four dock functions separately: emptying the dustbin into a bag, washing the mop, drying the mop and refilling the robot's water. A multifunction dock name does not tell you which of these it performs; the exact package does. The Roborock Q7 L5 package ships a small charging dock, so its combined dustbin and water tank is emptied and refilled by hand. The Dreame L40 Ultra Gen 2 PowerDock, the eufy Omni E28 station, the Roborock Saros 10R dock and the iRobot AutoWash dock all empty, wash, dry and refill.
Then read what stays manual. The multifunction docks in this catalogue have clean and dirty water tanks that you fill and empty yourself; published tank sizes run from 2.5 to 4.5 litres for clean water. Detergent dispensing is its own feature: eufy lists it as included, while Dreame sells the dispenser separately. Day counts such as 75 or 100 days per dust bag are maker estimates, and some makers do not publish the bag volume at all.
Read mop hardware and carpet behaviour literally
Mops come as a single flat pad, two rotating pads or a roller. Each is a different maintenance routine and none establishes measured stain removal. What matters for a mixed-floor home is what happens on carpet. Dreame states a 10.5 mm pad lift, Roborock a 17 mm lift plus automatic mop-mount detaching on the Saros 10R, iRobot a pad that retracts to the top of the robot, and eufy a roller that raises when carpet is detected in Vacuum Only mode. The Q7 L5 page documents no lift, so a rug there means a no-mop zone or a vacuum-only run.
Lift heights are nominal figures under the maker's own conditions. A thick rug can exceed them, and a feature that only works in one mode is not the same as a lift that works in every mode. Wash temperatures and drying durations describe the dock setting, not a hygiene outcome.
Treat navigation names as hardware, not results
LiDAR, 3D ToF, structured light, RGB camera and AI are descriptions of sensors and software. The Q7 L5, L40 Ultra Gen 2 and Omni E28 use a LiDAR turret; the Saros 10R replaces it with solid-state 3D ToF sensing to reach a 3.14-inch body; the Roomba Combo 10 Max navigates by camera. The maker pages say what the robot carries, and sometimes what it is designed to recognise. They do not establish how often it avoids a charging cable or a pet accident in your rooms, and this catalogue records no such test.
Height is the navigation fact you can act on. Published bodies range from about 80 mm to 111 mm here. Measure the lowest furniture you want cleaned under and compare it with the robot's height, remembering that a body dimension is not a tested clearance. Threshold figures work the same way: Dreame claims 2 cm, eufy 21 mm and Roborock 4 cm for the Saros 10R, each under its own test setup, while other pages publish none.
Handle suction and runtime numbers with care
Suction pressure in pascals is a figure each maker measures its own way, and the pages that publish it footnote it as internal lab data. iRobot publishes none, and Roborock's Saros 10R page names a technology rather than a number. This catalogue records the figure as manufacturer-reported where it exists and as unknown where it does not. It is never a cleaning result, and a missing number is not weak suction.
Runtime claims depend on mode. Dreame's 231 minutes is for Vacuum Only at Quiet suction; eufy's 216 minutes is vacuum mode at Standard and drops to 125 minutes with mopping. Roborock and iRobot publish battery capacity for the robots here but no minutes. Mopping, carpet boost and recharge-and-resume all change a real session, so compare the conditions as carefully as the number.
Confirm the account, network and exact US package
Every robot here is set up through the maker's app. The eufy user guide requires creating or signing into an account, and the Roborock Saros 10R manual states that only 2.4 GHz Wi-Fi is supported. iRobot sets Apple Home conditions: a recent iOS or iPadOS version for pairing and a home hub for automations and remote access. Where a page does not state the Wi-Fi band, check the manual before buying. Voice assistants and Matter are extra conditions on top of the base app, and none of these pages documents a required subscription.
Finally, pin down the package. Keep the item or SKU, the colour, the dock name and the box list together: X085020 for the Roomba Combo 10 Max with AutoWash dock, RR-Saros10R5-M2 for the Saros 10R, RR-Q7L55-M2 for the black Q7 L5, 010204AA001146 for the white L40 Ultra Gen 2, and the t2352111 listing for the Omni E28. Accessory bundles, extended-warranty listings and a sibling model with a similar name are different offers. This comparison gives you sourced specifications and their gaps; it does not provide a price, stock status or a tested winner.
Common questions
Does a bigger suction number mean a better clean?
No. Pascals are measured differently by each maker and footnoted as internal data. They describe a marketing figure, not cleaning performance, and some makers publish none.
If the robot name matches, is the dock the same?
Not necessarily. The same robot can be sold with a charging dock or a multifunction station. Check the exact package's box list for a dust bag, water tanks and mop washing before buying.
Can I use the robot without an app or account?
Buttons on the robot start basic cleaning, but mapping, zones, schedules and dock settings are app features. The eufy guide requires an account, and several robots accept only 2.4 GHz Wi-Fi.
