In-depth review
What it's like to own
The Lefant M210 is a basic robot that does one job: keep hard floors free of dust and pet hair between real cleanings. There's no roller brush, just a suction port, so long hair goes straight into the bin instead of wrapping.
It doesn't map your home. It uses a gyroscope and infrared sensors to run zigzag or random patterns, and the app lets you schedule runs and change suction. Owners say it gets confused when furniture moves and struggles with some debris, but it's durable and easy to live with.
At 2.99 in it's one of the slimmest robots here, so it reaches under most beds and sofas. Lefant doesn't publish suction, and the 120-minute runtime is measured on low power, so our suction score is zero until it does.
