Maria Diaz/ZDNET Follow ZDNET: Add us as a preferred source on Google. I've tested dozens of robot vacuums, and it's rare that I stick with only one of them. Yet I've been using the Ecovacs Deebot X11 OmniCyclone for over a month, and I'm in love. This is a flagship robot vacuum that's good enough to be the only one you'll need for years and years to come. It features the latest navigation and obstacle avoidance technology, some of the best cleaning power on the market, and easy maintenance. The best part? It's on sale during Prime Day for $1,200. Also: The best October Prime Day deals live now Most robot vacuum manufacturers claim they're shaking up the industry, yet few robots actually live up to this claim -- the Deebot X11 OmniCyclone is one of the exceptions. It's the perfect combination of technologies that Ecovacs has perfected over the years, featuring a 100W high-performance fan for suction, fast charging technology, a self-washing roller mop, and a bagless dust collector at the dock. This robot supports up to 19,500Pa of suction power and features Ecovacs' BLAST system, which automatically engages a 100W fan to suction deeper into rugs and carpets, removing more hair, dust, and debris than other vacuums. Also: This robot mower doesn't need a boundary wire and it's $900 off during Prime Day Beyond suction power, some of this robot's most unique abilities are precisely what put it over the top in my book. This robot features GaN fast-charging technology that tops off the battery each time it docks to rewash its mop or empty the dustbin. This ensures the robot can clean large areas without needing to return to the dock to recharge for an hour and then resume later. The Deebot X11 OmniCyclone is efficient enough to clean almost 900 square feet in my home without having to recharge. And it still has enough battery power left when finished to clean more areas, clean everything a second time, or do some spot cleaning. The battery is so reliable that you can always count on the robot to be available at your beck and call. Maria Diaz/ZDNET I've seen this type of bagless system on vacuum-only robots, not ones with a self-washing mop that requires clean and dirty water tanks at the dock. Yet Ecovacs finally made this a reality by creating the first flagship self-emptying and self-washing robot vacuum and mop with a completely bagless dock. The Ecovacs OmnyCyclone dock can hold approximately six weeks' worth of dust and debris. Simply empty it into the trash can and return it to its original position to continue working. The Deebot X11 also features a roller mop that is constantly scrubbed clean as it rolls inside the robot, so it always mops your floors with clean water. The mop also extends to clean along the wall and under cabinets for edge cleaning. The Ecovacs Deebot X11 OmniCyclone is available for $300 off during Prime Day, bringing its price down to $1,200.

How I rated this deal This robot has only been on the market for a month, and it's already one of the highest-rated models you'll find. It's also why the discount is so significant: a 20% discount a month after launch is a great way to save money on one of the best robots on the market. If you also consider that this robot vacuum is largely hands-free but that you won't ever have to buy extra dust bags, then you're saving even more money down the line. When will this deal expire?
