While the best robot vacuum deal on offer right now is for the Eufy Omni C20, it has dropped to $349.99 at Amazon — that’s a whopping $350 discount from its regular price of $699.99.
According to price-tracking site camelcamelcamel, along with CNET’s own pricing data, this is a lowest-ever price on an all-in-one mop and vacuum cleaner — especially good if you’re seeking something midrange.

Why This Eufy Omni C20 Deal Is So Good Right Now
Eufy’s Omni C20 is all about hands-off floor care. Its 7,000 Pa suction lands it at the high end of consumer robot vacuums, which often range from around 2,500 to 6,000 Pa. In actual use, the extra pull plays its part to extract grit from floorboard seams and dislodge embedded pet hair in low and medium-pile carpet. A rolling brush and side brush take care of surface debris as well as edge cleanups, and the Pro-Detangle Comb automatically sheds wrapped hair from the roller — good news for households with pets that shed.
On the mopping side, Eufy’s Mop Master system is capable of scrubbing at 180 rotations per minute with up to 6 N of pressure. That’s enough to penetrate through dried kitchen splatters and light shoe scuffs that some “drag-mop” robots simply spread around. With dual modules, the robot can sweep and then mop on a single pass, which it makes at random, then returns to a docking station where dust is emptied and the mop washed, after which it’s dried with room-temperature air — this amount of detail helping stave off odor and mildew.
How It Compares to the Competition on Price and Features
Even at this sale price, the Omni C20 is priced below quite a few all-in-one systems that skimp on key features. Roborock’s Q Revo (5,500 Pa) and Ecovacs’ T20 Omni (6,000 Pa) are highly rated for damp mop washing and drying, but they tend to cost a few hundred bucks more. High-end flagships such as the Roborock S8 Pro Ultra pile on features, like advanced obstacle recognition and hot-air drying, but still cost two to three times as much, even with seasonal promotions. On the other hand, iRobot’s Roomba Combo vacuums are very good at navigation and carpet cleaning but typically need either an additional accessory or a more expensive model for real-time mop scrubbing and pad care.
Specs aren’t everything — suction is measured differently by different manufacturers — but the C20’s combination of relatively high stated power, active scrubbing, and a self-maintaining dock for well under $400 is rare.

A value tier for people who want a real vacuum-and-mop system rather than just a vacuum with a wet cloth attachment.
Performance Notes and Practical Examples of Use at Home
On mixed floors, the C20’s powerful pickup should impress on hard surfaces and lower-pile carpeting where airflow and brush design matter more than raw specifications. The scrubbing mop is helpful with sticky spots, but as with most robots that don’t have an elevated mop mechanism, you should consider either placing no-mop zones around rugs or scheduling separate vacuum-only and mop runs. Homes with pets or toddlers for whom crumbs and drips materialize daily benefit most from the dock’s automatic rinsing and drying, which helps to keep the pad fresher between deep cleans.
Their real-world value comes in convenience. Owner surveys at Consumer Reports show auto-emptying docks increase satisfaction and usage rates: people use their robots more frequently when maintenance is minimal. Throw in mop washing, and you take away one of the largest pain points for hybrid machines.
What to Know Before You Buy the Eufy Omni C20
- Budget for consumables — the dust bags and mop pads do cost money; though replacement costs differ, they are a consideration in every self-emptying ecosystem.
- Keep the robot dock area organized and open to allow for proper alignment and servicing of the robot.
- With thick rugs, high thresholds, or tight gaps between dining chair legs, you should expect to do some room prep — no robot is fully set-and-forget in complex layouts.
- For the privacy-savvy, review the app’s mapping and privacy settings before your first run; big names like Eufy let you limit data sharing and keep maps local.
If you’re cross-shopping, see if competitors offer hot-air drying, auto-lifting mops, or onboard cameras for obstacle avoidance — nice-to-haves that can ratchet up prices. The C20’s room-temperature drying and strong scrubbing cover the basics without the premium tax.
Deal Bottom Line: Why This Offer Is Worth Considering
A 50% reduction down to $349.99 for an all-in-one robot that vacuums, scrubs, self-cleans, and auto-empties is rare. With camelcamelcamel confirmation of that being its lowest-ever price, the Eufy Omni C20 rises above the currently available robot vacuum deals for most homes in need of dependable daily maintenance without a lot of babysitting. If you’ve been looking for a real hybrid at sub-$400, this is the one to pull the trigger on.
