Our Take

Best for: Pet owners and busy families wanting automated vacuuming and mopping.

The iRobot Roomba Plus 4020 is a top-tier robot vacuum and mop combo that delivers exceptional cleaning performance. With 70 times more suction than older Roomba models, it easily picks up pet hair, crumbs, and debris. The DualClean mop pads scrub floors with downward pressure, and the AutoWash Dock automatically empties the bin for up to 75 days and washes/dries the mop pads, so you rarely have to intervene. ClearView LiDAR maps your home quickly and navigates around furniture, even in the dark. The app offers detailed customization, including vacuum-only, mop-only, or combo modes, plus carpet detection that lifts the mop pads automatically. On the downside, the dock is bulky and takes up a corner, and the mop pads require periodic replacement. At 35% off, this is a fantastic deal for anyone wanting hands-off floor care.

Price Analysis

At $399.99, this is 35% off the original $617.48. The 30-day average price was $617.48, and the 90- and 180-day averages were $487.76, so you're saving well below typical market prices. This is likely near an all-time low and an excellent time to buy.
