Lefant M310 Robot Vacuum

Yes, mostly. At 2.99 inches tall the Lefant M310 slides under beds and low furniture to pull out dust and hair. The catch is that it sometimes wedges itself under recliners and other low pieces, so block those spots off before a run if you won't be home to free it.

It's mixed. In some homes the coverage is thorough. In others the M310 repeats areas, gets lost or can't find its base without help. Clearing clutter and cords before a run gives the Lefant M310 its best chance of finishing on its own.

Yes. Run every day or two, it keeps tile and hardwood noticeably cleaner and handles dog and cat hair well. The brushless suction mouth on the M310 resists hair tangles, so there's less cutting hair off a roller, and the dual side brushes pull hair out of corners toward it.

Quiet enough to talk or watch TV nearby, about like a box fan. A few find it somewhat louder than that, so if you're sensitive to noise, schedule the Lefant M310 for when you're out of the room or out of the house.

Close to it in most cases: a little over 2 hours up to about 160 minutes per charge. Some units fall short of the advertised time, and it can run out on the way back to its base, which leaves the Lefant M310 stranded until you carry it home.

It's mixed. The app lets you set suction and see a simple map, but some units drop Wi-Fi and scheduled runs don't start. The M310 needs a 2.4GHz network, so if scheduling is flaky, check the robot is on that band first.
