AI-powered navigation in robotic vacuum cleaners promises efficient cleaning, but in small rental apartments, questions arise: Is constant scanning and mapping necessary, or does it lead to unnecessary power consumption? How does recording room data affect privacy when manufacturers send data to the cloud? And what alternatives exist if the device can't fully map the apartment? I'd love to hear your experiences and opinions on these aspects—how do you weigh the benefits against the effort and data privacy? What approach would you prefer when selecting such a device?
Are robotic vacuum cleaners with navigation AI actually useful for small apartments?

I've bought a Roborock S7 and a Xiaomi Mi Robot Vacuum-Mop 2 in the last two years – both use mapping and AI navigation. In my small 45 m² rental apartment, you hardly notice that the constant scanning uses extra power; the devices are in standby mode and only activate the LiDAR system shortly before cleaning starts. The difference in energy consumption compared to a simple "random-bounce" vacuum robot is practically negligible, but the cleaning is much more precise: corners, under furniture, and along walls are regularly reached without the machine driving around the room unnecessarily.
As for data privacy: Both manufacturers offer the option to store map data locally and completely disable cloud synchronization. In my case, I only enabled the cloud function for firmware updates and turned off map backups – so the layout of my apartment remains private. If the mapping fails for any reason (e.g., due to frequently changing furniture), the device can still be manually controlled in "Spot Clean" mode, which is a useful alternative for particularly small rooms or open floor plans. My recommendation: When buying, look for devices where you can optionally enable cloud storage, and check the energy consumption specifications in test mode. That way, you get the benefits of AI navigation without unnecessary data collection or high power consumption.
I tested a small LiDAR-mapping robot vacuum in my 30 m² studio: the scanner runs constantly, which increases energy consumption by about 10% and the device sends room maps to the cloud—something that gave me pause. In the end, I went for a basic model that just follows a random path; it cleans well and doesn’t collect any data, even if the coverage isn’t perfect. If privacy matters, disabling cloud mode or picking a vacuum without mapping is the safest bet.
