For a small apartment, you can completely abandon the wire. An excellent option for quick and local cleaning. For general cleaning with skirting boards, carpets, sofas . you have to wait a 4-hour recharge. Its pros: a full charge is enough to clean an apartment of 70m2 (on a medium, without carpets); in turbo mode, he tore off the grout for the tiles in places; always at hand, no need to get from somewhere in the pantry, unwind the cord, etc. Has cons: heavy, the spouse complains that the hand gets tired quickly; hair clogs in the rollers on the main brush, it is difficult to clean; non-removable battery; long charge; noisy (almost like a stationary vacuum cleaner)
