What the differences mean
Suction power
The Roborock Saros 20 Flow is rated at 36,000 Pa against 20,000 Pa on the Eufy E28, so the Roborock has far more headroom on deep carpet. Both handle hard floors and pet hair well in daily use.
Portable deep cleaner
The Eufy E28 includes a handheld cleaner that lifts out of the dock for sofas, car seats and stains, which the Roborock Saros 20 Flow does not offer. No floor robot can reach those jobs, so that is a real capability gap.
Height and low furniture
The Roborock Saros 20 Flow is 89.8 mm tall and the Eufy E28 is 111 mm, so the Roborock slides under more sofas, beds and cabinets. If your home has low clearance almost everywhere, the E28 will skip those spots.
Battery and recharge
The Roborock Saros 20 Flow is rated for up to 301 minutes and charges in about 2.5 hours, while the Eufy E28 is rated for 216 minutes and recharges in about 3.5 hours. On a large single floor the Flow is the one that finishes without stopping.
Which one to buy if
- you want one machine to clean floors and upholstery
The Eufy E28 ships a portable deep cleaner that lifts out of the dock for sofas, stairs and stains, which the Roborock Saros 20 Flow lacks.
- your furniture sits low to the floor
At 89.8 mm the Roborock Saros 20 Flow clears furniture that the 111 mm Eufy E28 cannot reach.
- you want the strongest suction in this pair
The Roborock Saros 20 Flow is rated at 36,000 Pa, well above the 20,000 Pa of the Eufy E28.
- you want the lower price and a quieter robot
The Eufy E28 costs less, is rated at 57 dB against 66.6 dB on the Roborock Saros 20 Flow and still brings a full self-cleaning station.
- you want the longest run on one charge
The Roborock Saros 20 Flow is rated for up to 301 minutes against 216 minutes for the Eufy E28, and it recharges in about 2.5 hours.

What owners say
Owners of the Eufy E28 describe a machine that maps the whole house on its first run and then largely looks after itself, and the feature they single out is the portable deep cleaner that lifts from the dock for sofas and upholstery. Hard floors and rugs come out visibly cleaner, the dock empties, washes and dries the mop and doses detergent, and many find it quiet while cleaning. The recurring complaints are a loud dock during emptying and mop washing, a tall, heavy body that misses low cabinets, and more routine upkeep than a basic robot.
