Both can wet-clean, but Q7 M5 relies on a passive pad and manual pad care while C20 adds spinning mops and an automatic care dock. The difference is the whole mopping routine.
This comparison is based on the UK listings and manufacturer information cited below. We have not tested these robots side by side, so the recommendation is about features and household fit rather than a measured cleaning winner.

The differences that affect everyday use
| Feature | Roborock Q7 M5 | Eufy Omni C20 |
|---|---|---|
| Mop system | Passive pad with adjustable water flow | Dual spinning mops |

| Advertised suction | 10,000 Pa | 7,000 Pa |
How your home changes the choice
Count the times you would remove and wash a pad in a normal week. If that task is already easy, a more complex station needs another clear benefit such as useful under-furniture access.
Choose Roborock Q7 M5 when…
Consider it when you want a mapped vacuum and can manage a basic mop yourself. A vacuum with occasional damp wiping and app-controlled water delivery.
Its water control adds flexibility, but increasing water is not a substitute for checking your floor-care instructions.
Choose Eufy Omni C20 when…
Consider it for hard-floor routines where low furniture and automatic pad washing matter. A relatively low-profile robot with an automatic mop-care dock.
Measure both furniture clearance and the space above the dock tanks: a slim robot can still come with a substantial station.
Limitations to check before ordering
- This Q7 M5 listing is not a Plus dock bundle. A dragged pad needs removing and washing by hand; do not assume powered scrubbing or mop lift.
- The listed 8.5 cm body still needs clearance above it. Room-temperature drying is different from heated drying, and the water tanks need attention.
Compare the complete UK purchase
Check the exact model, selected bundle and included station before comparing prices. Similar names can hide different mops, emptying systems or regional specifications. Include the parts you will regularly replace and the chores you will still do. Manufacturer and retailer descriptions establish advertised features; they do not provide an independent test of cleaning performance in your home.
| Check | What matters |
|---|---|
| Identity | Full model name, UK suitability and contents. |
| Ownership | Correct bags, filters, pads and solution availability. |
| Practical fit | Floor route, dock access and maintenance you can manage. |
