We've never had any staff but only have four rooms, so it has always required efficiency to get everything done if three or all four rooms are checking out and all four have new check ins.
Anything less than a full turn and its actually a pretty easy day to get everything done.
That is, if nobody stays beyond the 11am check out and nobody arrives a few hours early unannounced. LOL
The sound of vaccuuming in other areas of the house will usually prod along even the most stubborn late check out thankfully. And me greeting a really early arrival with toilet brush in hand usually gets the message across.
We're only talking a few times a year when that condition occurs.
Plus, my wife also works a full time job outside the B&B that only allows her a few hours of home time after breakfast has been prepared, served and cleaned up from, so good time management is how we've made the physical rigors of innkeeping look pretty easy to the casual observer.
Working as a well-oiled, complimentary team has served us very well also.
We carry our cordless phone with us everywhere, but aren't afraid to let it go to the message if we glance at it while its riinging and the display doesn't show a person's name or if it shows "toll-free", "unknown", etc.. or whatever the solicitor calls usually show.
We seem to get most of those type calls mid-day to our business line, and in the evening for our personal line because telemarketers aren't dumb.
They know their odds increase if they time the call for when either a business owner is there during the day or when a resident is home after work.
After the breakfast cleanup, doing the outgoing payment transactions and before check outs, I go to the laundry room and put the new sets of towels, linens, bottled waters, etc.. for each room in a pile.
I get the vaccuum, cleaning supply caddy, mini mop, paper towels, etc. ready to grab and take to the first room that has vacated. If there is any waiting time involved, that is when the pillow cases get ironed, information center organizing gets done, kitchen trash taken out, plants watered, etc.
Having lots of good quality cleaning tools really helps and stuff like the Mr.Clean MagicReach tool has been a real time and back saver. Some of these things are very ergonomically designed, so the strain and stress on your body is greatly reduced while cleaning effectiveness is increased.
I've also rigged both the smaller and large size Swiffer mops to accept old facecloths that can't even be used for makeup removal by guests anymore and they work great for light duty mopping of tile or wood floors.
So, on to actually cleaning a room. I strip the bed and pile the linens, towels, etc. outside the room door out of my way. Next, before I bring anything clean into a room and a thorough vaccuuming of every inch is done but vaccuum is left in room to do a second final sweep in case any stray hairs were in the air while cleaning and settled on a surface. Bathroom gets done first, bedroom next cleaning wise and then everything gets put back together.
Usually by the time I'm done with the first room, all the departing guests or existing guests have gone or left for the day, so now I can really move freely through the house without fear of disturbing anyone. The common areas are usually the easiest, so I leave those for last.
Outside, we have a 140' long porch. Here they are called "portals" and that needs to get blown and swept every two days along with the normal landscaping maintenance. Thankfully, our climate doesn't support manicured looking "lawns" so its not like we're mowing more than a few times a year. Xeric and drought tolerant landscaping choices have enabled us to focus more on weed control and pruning.
In a nutshell, organize yourself well, minimize trips back and forth to the laundry room, kitchen, etc. and try not to rush. Seems like every time, I go into chicken with head cut off mode, I drop something, miss something or make more trips back and forth.
Good luck and welcome to the forums.
