expression, godan verb (-ku)
hurriedly prepare one's home for guests
Rare idiomatic expression. Literally 'to sweep the garden with a mallet', it describes a frantic, last-minute tidying up before visitors arrive. Used metaphorically, not for actual cleaning with a mallet.
急な来客に、まるで横槌で庭を掃くような慌てようだった。
With the sudden visitor, it was a frantic rush, as if sweeping the garden with a mallet.
