Compare robot vacuum models

Compare exact configurations by the route they can fit and the station they require. The QV 35A uses twin spinning pads and a removable-tank wash/refill dock; Qrevo Edge 2 adds a retractable sensor and separately documented warm-water mopping and hot dock washing; Q7 M5+ uses a flat cloth and dust-only auto-emptying; Curv 2 Flow uses a distinct powered roller. The original Curv is listed at 4.1 inches, Curv S5X at 3.9 inches, and CurvX, Saros 10R, Saros 10 with R&D and Edge 2 at about 3.14 inches. Saros Z70 is also 3.14 inches, but adds an app-configured arm for a short list of light objects; its 108 obstacle-recognition count is not the number of things it can move. Edge 2 has no published numeric threshold-crossing maximum in its exact US sources, so a measurement from another model is not transferable. Edge 3 Pro lists 1.77 inches for a single level and a qualified 3.46-inch double-layer geometry; its 100°C specification is dock washing, not a stated floor-mop water temperature; its exact feature page also claims carpet cleaning up to 1.18 inches when manually enabled in the app. Roborock’s US product page said the Edge 3 Pro had not launched yet when checked on October 23, 2026, so it is a specification reference, not a current buying choice. The four Q10 packages pair S5's VibraRise 2.0 cloth or X5's automatic-lift pad with a standard charging dock or a plus dust-emptying dock. No Q10 package washes the mop. The R&D Saros 10 is the distinct configuration that requires a fixed water supply and drain. Saros 10R has a documented 4cm double-layer threshold claim and solid-state 3D ToF navigation. Saros 20 uses a 3.14-inch StarSight robot with rotating pads; Saros 20 Flow is 3.54 inches high and swaps those pads for a refreshed roller. Both advertise the same double-layer maximum only under qualified route conditions; neither exact U.S. source set gives a numeric floor-water temperature. Compare those two packages. Dock wash water and water used on the floor are separate specifications.
