Robot vacuums are a handy way to clean your floors when you don’t have a lot of time — but they also have a reputation for costing a small fortune. However, this Amazon deal proves that isn’t always the case. Right now, the Lefant M210 Robot Vacuum is 55 percent off, bringing the price down to under $100 — a rare find in a category where many well-reviewed models still run $300 or more. If you’ve been putting off adding a robot vacuum to your cleaning routine because of the price tag, this is the kind of deal worth grabbing before it’s gone.

Deal of the day

The Lefant M210 is a compact robot vacuum built for small spaces and pet-heavy homes. At 11 inches in diameter and just under three inches tall, it’s designed to slip easily under beds, sofas, and other low furniture. Instead of a traditional roller brush, it uses a brushless suction port powered by a digital motor, a design meant to pull in pet hair and dirt without the tangling that roller brushes can be prone to.

Beyond the compact build, the M210 offers six cleaning modes — automatic, planning, fixed point, edge, schedule and manual. It also has infrared sensors to help it navigate around furniture and avoid falls off ledges or stairs. You can download the Lefant app to set timers or run it on demand or use Alexa and Google Assistant to get it going. The vacuum automatically returns to its charging dock when the battery runs low, making it a low-maintenance option for everyday upkeep.
