Updated October 2026
Data from Amazon and official Eufy and Roborock sites.

It offers 190 minutes of rated runtime, 36,000Pa of suction and a dock that washes and dries its own mop. The Eufy 11S MAX runs about 100 minutes at 2,000Pa and has no mop, no map and no Wi-Fi at all, driven instead by its bundled remote. The Roborock also connects on both Wi-Fi bands plus Bluetooth and reaches Apple Home, SmartThings and Home Assistant through Matter. What the Eufy 11S MAX keeps is a much lower price, a slightly quieter 55dB against the Roborock's 64dB, and a bigger onboard bin since it has no dock to empty it for. Buyers who want set-and-forget cleaning with real smart-home control should get the Roborock Saros 20 Sonic; anyone who wants a bare-bones, quiet, budget vacuum for a small home should stick with the Eufy 11S MAX.

What the differences mean

Runtime

190 minutes against 100 means the Roborock Saros 20 Sonic can cover a much larger floor plan in one outing before it needs to recharge, where the Eufy 11S MAX is sized for a smaller space.

Mopping

The Eufy 11S MAX has no mopping hardware. The Roborock Saros 20 Sonic mops and its dock washes and dries the pads with warm air on its own, feeding from a 4 liter water tank.

Noise

The Eufy 11S MAX is rated at 55dB, quieter than the Roborock Saros 20 Sonic's 64dB, which is the more noticeable trade-off for the extra suction and the self-cleaning dock.

Connectivity

The Eufy 11S MAX has no Wi-Fi, Bluetooth or radio of any kind. The Roborock Saros 20 Sonic connects on both 2.4 GHz and 5 GHz Wi-Fi plus Bluetooth, and reaches Apple Home, SmartThings and Home Assistant through Matter.

What owners say

The Eufy 11S MAX is the only one of this pair with real owner feedback behind it, and two things come up again and again: how quiet it is, often described as quieter than a fan or an air conditioner, and how much fine dust and pet hair it picks up given how little it costs. Several owners explicitly say having no app and no Wi-Fi is a plus, not a missing feature, since there is nothing to set up or connect. The most common complaint is that it wanders without a saved map and can miss or repeat a spot, and a minority report side-brush motors wearing out within the first year.

Price history compared

Every price change of both, in the same store, so the gap between the two lines is what one costs more than the other.
