The latest robot vacuum innovation will leave clean freaks drooling - and it's the lowest price ever

I've gone hands-on with dozens of robot vacuums, but Eufy's new Omni E28 actually surprised me when it went to work in my house. Now, it's 40% off during Amazon Prime Day.

• The Eufy E28 robot vacuum, mop, and spot cleaner combination is available for $999.
• The mop performs better than more expensive flagships, and the water tank system doubles as a portable spot cleaner with a self-cleaning hose.
• Unplugging the spot cleaner also unplugs the charging station, and the spot cleaner requires you to brush it to scrub.
