Run the vacuum only while the house stays empty
Start the robot vacuum only after the home is confirmed empty, limit it to once a day, and send it back to the dock immediately if anyone returns early.
Best for: Households that want the vacuum to stay out from underfoot completely, including sending it home the moment someone returns.
Not for: A household without a presence signal tested across every regular occupant, or a vacuum that cannot be commanded to dock from automation.
Why this exists
A vacuum that starts when the house is empty is only half the job. It also needs to stop cleaning and return to its dock the moment anyone comes home early, and it should not restart every time someone steps out briefly during the same day.
Logic
- Trigger: The tested presence signal reports the home as empty during the chosen daytime window.
- Conditions: The vacuum has not already completed a cycle today.
- Action: Wait briefly to confirm the departure is real, then start cleaning.
- Wait / timeout: If the confirmed-empty period ends before the wait completes, skip the run for today.
- Stop condition: As soon as the presence signal reports anyone home, send the vacuum back to its dock immediately, whether or not the room it was cleaning is finished.
- Manual override: The vacuum’s own app or button can start, stop, or dock it at any time regardless of this automation.
What I used
Confirm the whole household has left and returned
Use your platform’s built-in presence feature (phone location or network connection) rather than a dedicated product. Test it against both departure and arrival for every household member before trusting it.
Robot vacuum with remote dock command
No personally verified recommendation yet. Confirm the vacuum accepts a return-to-dock command from automation, not only a manual app tap.
See recommended gear for the job-first checklist.
Setup notes
- Confirm the presence signal against a week of real comings and goings for every household member before using it here.
- Choose a daytime window and add a short confirmation wait before starting, as in the simpler auto-start recipe.
- Track a per-day completed flag so a brief errand does not trigger a second run once today’s cycle already finished.
- Reset the per-day flag at a fixed time, such as midnight.
- Add the return-to-dock action as its own rule so it fires immediately, independent of the start logic.
- Test by starting the vacuum manually and then simulating an early return to confirm it docks promptly.
Platform notes
The platform must maintain a daily-run state while also giving the arrival rule an immediate path to dock the vacuum. Presence, vacuum commands, and vacuum status all need independent testing. See the platform guides for broader fit and maintenance tradeoffs.
Amazon Alexa
I could not verify a universal Alexa routine pattern for multi-person empty-house confirmation, a daily-run flag, and immediate dock-on-return behavior. Vacuum skill actions and location triggers vary. Prefer the vacuum’s own controls unless the exact start and dock actions are exposed and every household arrival path has been tested.
SmartThings
The vacuum’s device profile must expose start, dock, and cleaning status before this recipe is possible. Use tested phone presence for Home and Away state. An advanced SmartThings Rule is a better fit than disconnected routines when the daily flag and immediate arrival branch must share state.
Hubitat
Use Hubitat Mode Manager for the household state and Rule Machine for the daily flag and separate arrival action. The exact vacuum still needs a compatible integration or driver with start, dock, and status commands. Test docking from every cleaning state before enabling automatic starts.
Home Assistant
Home Assistant is a technical fit for stateful vacuum automations, but I have not personally run it. Verify the current vacuum and presence integrations, then test that arrival always takes priority over the scheduled or delayed start path.
Advanced features
Skip a day intentionally
Offer a simple manual control that skips today’s run, for a day someone is working from home without leaving.
Notify on completion
Send one notification when the vacuum reports it has returned to its dock after a completed cycle.
Failure modes
- Vacuum keeps cleaning after someone returns: Confirm the dock command is wired to the presence signal directly, not only checked at the next scheduled interval.
- Vacuum runs again the same day: Confirm the per-day flag is being set and is not being reset by an unrelated automation.
- Vacuum never starts: Confirm the presence signal actually reports empty during the chosen window and that the per-day flag was reset that day.
- Vacuum docks and immediately restarts: Separate the stop logic from the start logic so a docking event does not itself look like a new empty-house signal.
- The presence signal disagrees with reality: Stop relying on it and retest with a longer confirmation wait rather than tuning indefinitely.
FAQ
How is this different from a simple auto-start recipe?
This recipe adds a once-per-day limit and immediately docks the vacuum if anyone returns early, instead of only starting a cleaning cycle.
What happens if someone comes home while the vacuum is cleaning?
The vacuum is sent back to its dock as soon as the tested presence signal reports anyone home, rather than finishing the room it is in.
Can this run more than once if someone leaves and returns several times in a day?
No. A per-day flag prevents a second run once the vacuum has completed a cycle that day.
