Upgrade your robot vacuum while the Roomba Plus 405 Combo is less than $300
SAVE $119: As of Aug. 5, the iRobot Roomba Plus 405 Combo is on sale at Amazon for $299.99. That’s nearly 30% off its usual $419 price tag.
Members of the Roomba fan club who want to upgrade their robot vacuum should check out this deal on the Roomba Plus 405 Combo. While the FCC’s robot vacuum ban in the U.S. doesn’t revoke authorization for previously approved devices, it may result in low stock and, therefore, higher prices. In other words, save those dollars while you can.
As of Aug. 5, the iRobot Roomba Plus 405 Combo is on sale at Amazon for only $299.99, down from $419. That’s a savings of 28% or $119. That also matches the lowest price we’ve seen on this model.
While Mashable’s resident robot vacuum tester Leah Stodart is not a huge fan of iRobot’s devices, she has tested and approves of the Roomba Plus 405 Combo. It’s a mid-range robot vacuum mop combo, which means it can vacuum your home, mop your floors, then wash and dry its own mopping pads. It lacks small obstacle avoidance tech, which is a bummer, but it does offer consistently solid smart mapping, fantastic edge cleaning from dual spinning mopping pads, and a docking station that continuously refreshes your mopping pads for four weeks and auto-empties debris for 75 days. We wouldn’t recommend it if you have a ton of small toys and cables laying around, but for everyone else, the lack of small obstacle avoidance shouldn’t be a huge dealbreaker.
There are plenty of robot vacuum mop combo devices on the market in 2026, but finding a model for under $300 that’ll actually get the job done isn’t easy. At only $299.99, the Roomba Plus 405 Combo is kind of a steal.
