The Roomba 104 Combo, despite being a low-tier model, impresses with its efficient lidar navigation. It avoids carpet while mopping, handles vacuuming with ease, and adapts well to our home's layout. It's a fantastic option for first-time robot vacuum owners, bringing both convenience and value. The inbuilt vacuum compartment in the charging dock is a handy feature. While it can't reach tight corners, its versatility in vacuuming and mopping is impressive. At $520, it's a commendable investment. If you find it on sale for $350 or less, it's a stellar deal for first-time buyers. A must-have for simplifying your cleaning routine!
