Roomba Plus 405 Combo
For busy homes with pets and mixed floors, this Roomba pairs LiDAR mapping with an AutoWash dock so you mostly schedule cleans and forget about emptying or washing pads for weeks.
If you want hands-off floor care for homes with pets, kids or a mix of carpets and hard floors, this robot vacuum-and-mop combo aims to replace the weekly slog of vacuuming and mopping. It combines Roomba-style pickup with spinning mop pads and an automated base so you spend far less time maintaining the machine than the floors. ## What makes it worth it The standout is the AutoWash dock: iRobot says it auto-empties debris for up to 75 days and washes and dries mop pads for about four weeks based on one mopping run per week, which hugely reduces upkeep. The cleaning system pairs spinning DualClean mop pads (200 RPM) with SmartScrub back-and-forth scrubbing for deeper stain removal, and ClearView LiDAR maps your home in minutes for neat row-by-row coverage even in the dark. Carpet detection lifts the pads automatically so you can mop and vacuum in a single run, and the Roomba Home app plus voice assistant support give straightforward control and scheduling. ## Where it falls short This is a premium, feature-heavy system and that shows in the price; some early reviews note the unit delivers reliable everyday cleaning but stop short of class-leading performance in every metric. iRobot’s suction figure is given relative to much older 600-series models rather than as an absolute Pa number, which makes direct comparison with rival docked systems harder for power-hungry buyers. Buyers who want near-zero maintenance and consistent mapping will find this very compelling; buyers prioritising the absolute strongest suction numbers or the lowest upfront cost should look elsewhere.
