How to properly design the database "booking"?

Question

MySQL

Hello! I need to properly design a DB (Hotel Room Cleaning). Cleaning takes place every week in the occupied room, but the client can appoint a cleaning day (for example, every Tuesday)! For the rest of the rooms (not booked, cleaning is not necessary). But you can also assign a separate room cleaning.
What I did. Now I have 3 tables rooms, cleanings, workers.
Cleanings (
id_cleaning bigint (20) NOT NULL
date_cleaning date NULL
id_room int(11) NULL id_worker
int (11) NULL
notes text NULL

(
id_room int(11) NOT NULL
number varchar(5) NOT NULL
last_cleaning date NULL // Last cleaning optional
status tinyint(4) NULL // Room status optional
cleaning_day tinyint(7) NULL // Day for regular room cleaning
lock_start date NULL //start of booking number
lock_finish date NULL // check-in of the client
)
Workers ( //The one who will clean the room,
id_worker int(11) NOT NULL
name varchar(50) NOT NULL
phone varchar(20) NULL
)
At the output in my program You should get a similar table like this:

I'm waiting for your advice, what can be added, what can be removed! thank!

Made it like this!
And I define actual reservations with queries like

SELECT * 
FROM reservation
LEFT JOIN rooms ON rooms.id_room = reservation.id_room
WHERE reservation.lock_finish >= CURDATE()
