Eufy Omni C28 robot vacuum drops to $449.99 for Prime Day

Prime Day has turned robot vacuums into one of Amazon’s most visible deal categories, and the Eufy Omni C28 shows how far the segment has moved toward the mainstream. The vacuum-and-mop hybrid was marked down to $449.99, a $350 cut that puts features once reserved for premium models into a far more accessible price range.

The Omni C28’s hardware makes the discount meaningful. Eufy says the machine delivers 15,000Pa suction, uses a HydroJet self-cleaning roller mop, and comes with DuoSpiral detangle brushes meant to reduce hair wrap. Its 5-in-1 Omni Station automates dust emptying, mop washing, water refilling, hot-air drying and wastewater collection, and Eufy says the system can support hands-free cleaning for up to 75 days.

That feature set matters because it helps explain why robot vacuums are becoming less like gadgets and more like appliances. The value proposition is no longer just about automated floor cleaning, but about reducing the number of small chores that come with upkeep. A machine that can vacuum, mop and then clean its own mop station shifts the burden from daily labor to periodic maintenance, which is exactly the kind of upgrade that can make a robot vacuum feel practical rather than novel.

The timing also says as much about Amazon as it does about Eufy. The Verge’s Prime Day 2026 guide said the event began on June 23, 2026, and Eufy described Prime Day as an annual, member-only Amazon sale when robot vacuums are often much cheaper. That pattern creates a recurring question for shoppers: are these discounts evidence that the category has matured, with flagship-level features now arriving at lower prices, or are they simply the familiar Prime Day price drops that make a deal look bigger than the underlying trend?

For the Omni C28, the answer may be both. The $449.99 price shows how quickly robot vacuums are moving downmarket, but the real measure of progress will be whether those features stay within reach after the sale ends. If they do, the category is maturing. If not, Prime Day remains the best argument for buying one.
