RoboVac 30C cleans very thoroughly, it managed to reach all areas of my long, thin lounge quickly, cleaning most areas multiple times and it also coped well with my medium-pile carpet without juddering when travelling against the nap. It is operated via the remote control, which also gives you steering controls and the ability to find the vacuum or send it home. You can also carry out all these actions via the companion app and set up a cleaning schedule, so you can have the bot clean at specific times of day – when you’re out at work, for instance. Alternatively, you can start and stop cleaning using a voice command via an Alexa- or Google Assistant-powered smart speaker.
