The Ambient tested the in its home-technology lab. It reports removing dried coffee and red-wine stains in one pass and clearing flour from carpet in two passes.
The track-style mop also collected most debris left along a kitchen plinth after vacuuming. Dried ketchup was harder: a visible mark remained after three passes and needed cleaning spray before another run removed it.
The reviewer reports avoiding shoes, cables and simulated pet mess. These results describe that lab's tests, not universal performance. The mop lifts only 10 mm, which limits its suitability for deeper carpet.

Limits
Third-party lab tests; 10 mm mop lift limits thick-carpet flexibility.
