Price history
eufy S1 HydroJet specifications
The numbers that matter first, then every fact by group. As published by the maker or the shop we read it from.
eufy · on the market since December 2024
Consumables: a 2.5 l dust bag in the station.
Suction and brushes 2 facts
- Suction power
Suction in pascal, as the maker measures it. More pascal helps on carpet, but it says little about how well the robot picks grit off a hard floor.
- 8,000 Pa
- Anti-tangle brush
A brush that guides hair to the side instead of letting it wind around the shaft. It saves the cutting work in homes with long hair or pets.
- yes
Mopping 3 facts
- Mop type
How the mop is built: flat pads, two spinning discs or a roller. Discs press harder on dried-on dirt, a roller rinses itself while it works.
- roller mop
- Mop lift on carpet
How far the robot lifts the mop when it drives onto a carpet. From about 10 mm a medium pile stays dry.
- 12 mm
- Mop refreshed while mopping
The robot returns to the dock during a run to rinse the mop, instead of pushing dirty water around.
- yes
Dock 11 facts
- Empties the dust bin
The dock empties the robot’s dust bin, usually after every run. You only empty the dock’s bag or bin.
- yes
- Bagless
The dock collects dust in a bin instead of a disposable bag. No bags to buy, but you empty it yourself.
- no
- Dust bag capacity
How much the dust bag in the dock holds.
- 2.5 l
- Washes the mop
The dock washes the mop for you, so you do not rinse it by hand.
- yes
- Dries the mop
The dock dries the mop afterwards, so it does not sit there wet and start to smell.
- yes
- Hot-air drying
Drying is done with warm air instead of cold. It is faster and it helps against smell.
- yes
- Dispenses detergent
The dock mixes detergent into the water itself, from its own bottle.
- yes
- Plumbing hookup
The dock can be connected to the tap and the drain, so you never fill or empty a tank. It does need a connection nearby.
- no
- Clean water tank
The clean water tank in the dock, which wets the mop.
- 3 l
- Dirty water tank
The tank that catches the dirty water from the mop. You empty this one yourself.
- 2 l
- Dock height
The height of the dock. Mind a shelf or a window sill above it.
- 67 cm
Navigation and obstacles 4 facts
- Navigation
How the robot maps your home and follows that map. Lidar measures with a laser and works in the dark, a camera looks along and recognises more.
- built-in LiDAR, no turret
- Obstacle avoidance
How the robot sees loose things on the floor, such as cables, socks or a pet accident. A camera with depth sensing sees more than a bumper that reacts on contact.
- AI camera
- Climbs thresholds up to
The highest threshold the robot takes, as the maker states it. Measure your own: the step into a bathroom or onto a balcony is often higher.
- 20 mm
- Climbing system for high thresholds
An extending leg or wheel that carries the robot over a high threshold. Without one it usually stops at about 2 cm.
- no
Robot 3 facts
- Robot height
How tall the robot is. It decides whether it fits under your sofa, bed or cabinet.
- 9.6 cm
- Robot weight
What the robot weighs. It counts most if you carry it up a staircase every day.
- 5.27 kg
- Noise
The noise in decibels, in the setting its source names: makers mostly give the standard setting, shops often the highest. 65 dB is like a vacuum at half power, 55 dB like a conversation.
- 63 dB
Battery 2 facts
- Battery capacity
The capacity of the battery. It hints at the runtime, but how much the robot draws counts just as much.
- 4,600 mAh
- Runtime per charge
How long the robot cleans on one charge, at its quietest setting. After that it recharges and carries on where it stopped.
- 277 min
Smart features and warranty 1 fact
- Voice assistants
Which voice assistants the robot works with, such as Google Assistant or Alexa.
- Alexa, Google Assistant
