How we verified these figures
Nothing on this page is copied from a press release. Each unit spends a month installed in a real home, not a bench. A three-bedroom flat with sixty existing connected devices, a congested 2.4GHz band, and deliberate router reboots to see what recovers on its own.
| What we measure | How |
|---|---|
| Response time | Command to physical action, measured a hundred times across the day, reported as a median and a worst case. |
| Reliability | Failed or dropped commands as a percentage over the full month, logged automatically. |
| Recovery | Time to come back online after a power cut and after a router restart, five trials each. |
| Local control | Whether the device still works with the internet connection physically unplugged. |
| Setup | Timed from opening the box to a working automation, by someone who has not used the app before. |
We deliberately do not publish advertised range figures, which assume an empty room and no other radios. Every home’s radio environment is different. Reliability here is a strong signal, not a guarantee.
How it compares in the category
A specification only means something next to the alternatives. These are the smart Home we have measured under the same conditions.
| Model | Released | Price | Our score | Best for |
|---|---|---|---|---|
| Meross Smart Plug Mini | 2024 | £12 | 4 / 5 | Anyone starting a smart home without committing to an ecosystem |
| Aqara Presence Sensor FP2 | 2023 | £74 | 4 / 5 | Anyone whose lights keep switching off while they sit still |
| Philips Hue Bridge Pro | 2025 | £89 | 3 / 5 | People who have outgrown the standard bridge |
| Aqara Hub M3 | 2024 | £119 | 4 / 5 | Anyone who wants a smart home that survives an outage |
| Nest Doorbell (wired, 2nd gen) | 2024 | £179 | 4 / 5 | Households expecting deliveries who want reliable package alerts |
| Eufy S3 Pro Cam | 2025 | £219 | 4 / 5 | Anyone who refuses a monthly fee for their own footage |
What the spec sheet leaves out
- Sustained performance — the suction figure above is a capability, not a promise about what happens after twenty minutes
- How it behaves when warm, which is where most of the difference between similarly specified smart Home actually lives
- Software support length, which decides how long this stays usable and appears on no specification sheet we have seen
- The thing we actually noticed most: it cleared a cable, two shoes and a charging brick across ten runs
What the numbers mean in use
Specifications describe capability, not experience. In practice the detail that mattered most was this: it cleared a cable, two shoes and a charging brick across ten runs. That is the sort of thing a table cannot capture.
Strengths on paper and in practice
- An extending side brush that genuinely cleans edges and corners
- Excellent obstacle avoidance
- A dock that handles emptying, washing and drying
Known limitations
- Very expensive
- A bulky dock
- Proprietary dust bags add ongoing cost
Who this suits
This hardware is a good fit for households with pets, hard floors and no patience.
Behind this page
This reference page is written from the same testing notes as the reviews it supports, and it is revised whenever the hardware or the software underneath it changes. Where a figure appears here it has been measured rather than quoted from a specification sheet.
If something on this page no longer matches what you are seeing, it is out of date rather than disputed — tell us and it gets checked again.
