iRobot and its Roomba line have been the benchmark for robot vacuums. When it comes to the top of home cleaning luxury, the Roomba Plus 405 combo robot vacuum and mop (including a a cleaning dock) is a real reference point. This product has only just been released and, up until now, has never been discounted. For (early) Prime Day, Amazon has an amazing 50% discount and brings the price down to $399 from its usual price of $799. Looks like Amazon is clearing out stock with no margin left, make sure you don’t miss this opportunity. See at Amazon Complete Cleaning System The Roomba Plus 405 is a complete cleaning system that is designed to handle both mopping and vacuuming with amazing efficiency. It possesses 70 times more suction power than the Roomba 600 series and devours messes ranging from everyday crumbs to stubborn pet footprints. The dual spinning mop pads (when paired with SmartScrub technology) deliver double the scrubbing power and downward pressure of standard vacuum and mop modes so even dried-on grime and dried-up spills get cleaned appropriately. With cleaning solution or even water, it performs amazingly well on carpets and hard floors. The ClearView LiDAR system maps your house quickly and optimizes coverage for an in-depth clean every time. It moves smoothly around furniture and obstructions and special sensors prevent it from tumbling down stairs or getting stuck. This intelligent mapping allows you to target the cleaning to specific rooms or zones with Clean Zones and you can even set Keep Out Zones to avoid sensitive spots or pet food bowls. The AutoWash dock is a revolutionizer and offers up to 75 days of self-emptying and four weeks of mopping and pad washing with zero involvement. The dock is continuously rinsing and drying the mop pads so you receive a sanitary clean, day after day. This way, you can enjoy a spick-and-span home for weeks at a stretch without lifting a finger. Scheduling your cleaning has never been easier with the latest Roomba Home app: Easy to navigate, the app enables you to make personalized cleaning schedules, track the condition of your filter, receive time estimates, and see the areas that need the most cleaning. You may also instruct your robot using your voice assistant of choice or simply push the buttons on the unit itself. This is the first time this flagship Roomba has been discounted, and at half price, it’s an offer you won’t want to miss. See at Amazon
