Q7 L5 vs L40 Ultra Gen 2 vs Omni E28: how much dock do you want?
Three LiDAR-navigated vacuum-mop robots, from a plain charging dock to stations that empty, wash, dry, refill and dispense detergent.
The decision in brief
How the options differ
The Q7 L5 package ships a charging dock only, so the combined dustbin and water tank is handled by hand. The L40 Ultra Gen 2 PowerDock and the Omni E28 station both empty the bin, wash and dry the mop and refill the robot. The mops differ too: a flat pad, dual rotating pads or a self-cleaning roller. Decide which chores you want automated before comparing the maker figures.

The buying guide
Package and specification details
List the dock chores each package actually includes
Q7 L5: none, with a 160 x 70 x 101 mm charging dock. L40 Ultra Gen 2: auto-empty into a 3.2 L bag, hot-water mop washing, hot-air drying and refilling from a 4.5 L clean tank; the detergent dispenser is a separate purchase. Omni E28: auto-empty into a 3 L bag, roller washing, 95-122°F drying, refilling from a 2.5 L tank and automatic detergent dispensing. All dock tanks are still filled and emptied by hand.
Q7 L5 documents carpet suction boost but no mop lift, so plan mop-free runs or no-mop zones for rugs. L40 Ultra Gen 2 states a 10.5 mm pad lift and a pad that extends 4 cm toward edges. Omni E28 raises its roller when it detects carpet in Vacuum Only mode and adds a detachable portable deep cleaner for fabric. None of these figures is a measured stain or carpet result.
Keep height, thresholds and runtime conditions together
Body heights are 99 mm, 97 mm and 111 mm. Dreame claims 2 cm threshold crossing and eufy a 0.83 in (21 mm) obstacle clearance; Roborock publishes none for the Q7 L5. Runtime claims use different conditions: 231 minutes for the L40 Ultra Gen 2 in Vacuum Only at Quiet suction, 216 minutes for the Omni E28 in vacuum mode at Standard, and no figure for the Q7 L5. Do not read them as a ranking.
Not in any comparable sense. Each maker reports its own in-house figure under its own method; Dreame and Roborock both footnote theirs as internal lab data. Treat the numbers as marketing descriptors, not cleaning performance.
All three are app-controlled. The eufy user guide requires creating or logging into a eufy account; the Dreame and Roborock Q7 L5 pages do not state the Wi-Fi band, so confirm it with the manual before buying.
These manufacturer specifications do not establish measured performance, noise, long-term reliability or running cost. We have not independently tested these products. Check current prices, stock and operating-space instructions with the seller and manufacturer.

Cleaning type
Whether the robot vacuums only or vacuums and mops, and any extra cleaning tool in the package.
A vacuum-and-mop robot still needs water handling. Read the mop hardware and dock fields before assuming hands-free mopping.
