Anker Eufy T290GA10 main brush for Omni E25, E28

Anker Eufy T290GA10 — robot vacuum main brush for the Omni E25, E28. A roller with bristles and a rubber edge is the compromise between carpet and hard floor: bristles beat sand out of the pile, rubber stops hair from winding round the shaft. Change the brush guard with the roller: a worn edge no longer presses debris against the brush and some of it simply gets flung across the floor.
