The investigation
5 questions this comparison examines
How many independent maps can each vacuum store
Multi-floor homes need separate maps per level. Some vacuums store unlimited maps, others cap at a lower number. This section shows the mapping ceiling each unit supports.
Dreame X50 Ultra
Roborock S8 MaxV Ultra
Ecovacs Deebot X2 Omni
Combo j9+Dreame X50 Ultra officially supports up to 4 maps with automatic switching. Roborock S8 MaxV Ultra matches this specification.
Ecovacs Deebot X2 Omni stores unlimited maps per official app behavior; no documented ceiling.
Roomba j9+ creates a single map per home; users switching floors must erase and rerun mapping or manually segment via the app.
Does the dock work on multiple floors without relocation
A multi-floor home with one dock means moving the unit between levels or accepting incomplete cleaning. This section examines dock flexibility and whether each vacuum can operate independently of its dock station.
Dreame X50 UltraRoborock S8 MaxV UltraEcovacs Deebot X2 OmniCombo j9+Dreame and Roborock both list 60-70min runtime; dock cycles take ~10min. Owner reports confirm dock-to-ready time is consistent across floors.
Ecovacs Deebot X2 Omni supports per-floor scheduling; users can queue cleaning routines for different maps in sequence.
iRobot Roomba j9+ offers longest runtime but lacks per-floor scheduling; users must manually restart or move the dock.
How heavy is the vacuum for carrying between floors
If the dock stays upstairs, the vacuum must move by hand to the lower floor. Weight and ergonomics determine whether this routine is reasonable or burdensome.
Dreame X50 UltraRoborock S8 MaxV UltraEcovacs Deebot X2 OmniCombo j9+Roborock S8 MaxV Ultra is the lightest at 4.1kg; iRobot Roomba j9+ at 2.4kg is the outlier but has a smaller tank.
Ecovacs and Dreame both include carry handles. Owner reports note the heavier tank capacity (2.0L) on Ecovacs makes repeated floor transitions more tiring.
Can each robot maintain separate schedules per floor
Multi-floor homes benefit from staggered cleaning: upper floor on Monday, lower floor on Wednesday. This section shows whether the app supports per-map scheduling without manual intervention.
Dreame X50 UltraRoborock S8 MaxV UltraEcovacs Deebot X2 OmniCombo j9+Dreame and Roborock both assign a single global schedule; users must manually select the map before each run or accept single-floor cleaning.
Ecovacs Deebot X2 Omni allows users to save multiple cleaning routines per map and queue them across different floors within the app.
iRobot Roomba j9+ lacks map-based scheduling; it treats all data as part of a single home object with one active schedule.
How strong is the WiFi signal to the dock between floors
If the dock is upstairs and the robot cleans downstairs, signal loss can trigger connection dropouts or manual intervention. This section shows real-world WiFi dependency per unit.
Dreame X50 UltraRoborock S8 MaxV UltraEcovacs Deebot X2 OmniCombo j9+Dreame and Roborock both support WiFi 5; real-world owner reports indicate 30-40m range through 2-3 walls is typical.
Ecovacs Deebot X2 Omni includes WiFi 6 support, extending range and throughput; third-party benchmarks show 40-50m typical range.
iRobot Roomba j9+ stops operation when signal is lost rather than auto-returning, requiring app intervention or manual pickup.
In closing
What the evidence shows
Patterns that emerged across the questions above.
Ecovacs stands alone on per-floor scheduling
Of the four, only the Deebot X2 Omni explicitly supports separate schedules per map. The other three require manual intervention to switch floors, a critical limitation in multi-floor homes.
Map storage capacity shows a divide
Ecovacs offers unlimited maps while Dreame and Roborock cap at 4. The Roomba supports only a single map, making it effectively unsuited to multi-floor environments without erasing prior floor data.
Battery and tank capacity trade off with carrying
Longer runtime (Roomba j9+ at 80min) is offset by the robot's light weight. Heavier units like the Ecovacs (4.8kg) demand more physical effort if the dock cannot stay on every floor.
