Leads on	Cleaning Adhesion Coverage	Safety Ease of Use Reliability Value
Pros	Corner brushes and elastic balls, which Dreame says raise corner coverage by 90% Planned route at 14 cm/s that resumes after an interruption and returns to its start Rated for panes up to 2.5 × 4 m, down to 30 × 40 cm, on glass, marble or tiles	Seven modes on a planned route that resumes after an interruption and returns to start Frame detection from 2 mm, obstacle detection from 4 mm Pressure compensation and 30 minutes of grip after a power cut
Cons	No power-cut backup stated for the plain C1 3,300 Pa sustained vacuum; the 5,500 Pa peak is with compensation 80 ml tank with no area-per-fill figure, only a 60-minute cycle	5,300 Pa in standard mode, the lowest figure among the Winbots Needs a socket: 5.5 m cord plus a 1.2 m mains lead, no battery station 60 ml tank rated for 40 m², and no claim for the corners
Best for	Tall panes and stairwell glass where the route and the reach matter Buyers who want the corners done and the noise kept down	Ground-floor and interior glass close to a socket Anyone who wants the Winbot route planning for the least money
