Introducing the 850T

This robot vacuum-mop hybrid can be controlled with an app wherever you are. Just make sure your wifi is 2.4GHz. It can vacuum dust, hair, and miscellaneous garbage.

This hybrid cleaner can vacuum, mop, or both. To get started with the mopping feature, snap the water tank on and wet the mopping cloths.

This compact robot is only 8.3 cm high, so it can effectively clean corners, under sofas and beds, and the whole nine yards. The vacuum performance is quite good, but the mop performance is okay at best as you still need to manually mop stubborn stains yourself. On the bright side, at least the robot mop does most of the work for you!

If you have fragile furniture, the equipped magnetic tape will prevent the 850T from going to restricted areas. Generally, the 850T is quite aware of its surroundings. The 850T also packs anti-fall technology to avoid falling off heights. In case you were wondering, the 850T does not go on random paths.

In silent mode, the 850T can run for 120 minutes, which is impressive. It will automatically go back to the charging dock if the battery is running low.

The 850T is compatible with Google Home and Amazon Alexa.

Vboost technology

Whenever a carpet is detected, the 850T automatically boosts its suction power to max mode to ensure a thorough cleaning. Whenever it leaves the perimeter of the carpet, it switches back to the previous mode. The 850T climbs carpets quite well.

IPNAS 2.0 intelligent positioning system

Thanks to this sophisticated technology, the 850T can achieve systematic positioning and planning within a few steps.

Five cleaning modes

  1. Auto-cleaning involves an S-shaped pattern of movement followed by cleaning a room’s edges.
  2. Edge mode involves cleaning around a room.
  3. Spot mode cleans a specific area within a few-feet radius.
  4. Single-room mode cleans for about half an hour.
  5. Floor mopping is as obvious as it sounds, but remember to install the water tank first.

Three suction levels

We mentioned silent mode earlier. There are also standard and strong modes, the latter of which we also mentioned earlier.

Pros & Cons

  • Good vacuuming performance

This is a decent robot vacuum-mop hybrid, although its mop feature can be improved.
