Naturally, it is mainly solid wood floor. Is the surface of your floor painted or made of wear-resistant paper? In fact, the labor cost is included in the price of essential oil. If it is a composite floor (that is, the surface is made of wear-resistant paper), mop it, and you don&;t need maintenance. Buy that essential oil (actually wax) for free maintenance. Maintenance of solid wood floor is waxing. Just watch how many times he gives you maintenance. Negotiate the price. If it is painted, wax it.
