Cleaning & Performance

Mopping
No
Mop Lifting
No

Mop Lifting

Smart function! As soon as the vacuum steps onto a carpet, it automatically lifts the wet mop so it can continue cleaning without wetting your carpet.
Suitable for Carpets
No

Suitable for Carpets

A special function that allows the vacuum to adapt to the needs of carpets, ensuring that it will remove dirt even from between the fibers.
Carpet Boost
No

Carpet Boost

As soon as the vacuum detects that it is on a carpet, it automatically boosts to maximum power to suck up the dust hidden deep inside.
Anti-Tangle
No

Anti-Tangle

The brush is designed so that hair does not get tangled around it, saving you from having to clean the vacuum frequently
with HEPA filter
No

with HEPA filter

The "guardian" of the air. It traps almost everything (pollen, dust mites, microparticles), making it essential if there are allergies in the home.
Extendable Brush/Mop (Extendable Arm)
No

Extendable Brush/Mop (Extendable Arm)

The brush or mop extends outward to reach and thoroughly clean corners and edges along the walls.

Navigation & Intelligence

Navigation Type
Bump

Navigation Type

Bump

The vacuum changes direction every time it gently touches an obstacle.
with LIDAR
No

with LIDAR

The top navigation technology. The vacuum features a rotating Laser sensor (like a "beacon") that scans the home with absolute precision, even in complete darkness, creating a perfect digital map.
with Camera (vSLAM)
No

with Camera (vSLAM)

The vacuum uses a built-in camera to "see" the space and furniture, just like the human eye. In this way, it understands the layout of the house and calculates its route.
with Gyroscope
No

with Gyroscope

A smart and economical navigation method. The vacuum "remembers" the turns and distances it has covered, allowing it to move in organized straight lines instead of randomly around the space.
Obstacle Avoidance with AI
No

Obstacle Avoidance with AI

The vacuum has "artificial intelligence". It doesn't just see an obstacle, but understands what it is (e.g. a sock, a cable, or pet waste) and maneuvers to avoid it without getting stuck.
Multiple Mapping
No

Multiple Mapping

If you have a multi-story house, the robot vacuum can remember the map of each floor separately, so it doesn't get confused when you move it between floors.
Selection of Cleaning Areas (No-Go Zones)
No

Selection of Cleaning Areas (No-Go Zones)

Design "invisible walls" on your mobile! You can tell the vacuum not to approach specific areas or even entire rooms.
Pet Camera Live View
No

Pet Camera Live View

Become a "spy" on your pets! You can watch live from your mobile phone what your dog or cat is doing while you are away from home.

Base & Charging

with Charging Base
No

with Charging Base

It is the "home" of the vacuum. A fixed point where the device returns to recharge its battery, so it is always ready for the next cleaning session.
Automatic Charging
No

Automatic Charging

Forget about battery anxiety! When the vacuum feels tired, it automatically returns to its base, recharges, and—if it hasn't finished—continues cleaning exactly from where it left off.
Fast Charging
No

Fast Charging

For homes that never stop. The vacuum charges its batteries much faster than usual, so it can do a second or even third round of cleaning in the same day.
Self-Emptying Station
No

Self-Emptying Station

The base "sucks" the dust from the vacuum and stores it in a larger bag. This way, you only need to empty the base once every 1-2 months, instead of every day.
Self-Cleaning Mop
No

Self-Cleaning Mop

No more washing mop pads by hand! As soon as the robot vacuum returns to its base, special brushes and clean water automatically wash its mops, so they are perfectly clean for the next mopping session.
Mop Washing with Hot Water
No

Mop Washing with Hot Water

After the mop cloths are washed, the base dries them with hot air. This is the secret to preventing any musty or moldy smell, keeping them hygienic for you and your family.
Mop Drying with Hot Air
No

Mop Drying with Hot Air

Just like we wash the dishes! The base heats the water to dissolve grease and tough dirt from the mop cloths, providing ultimate disinfection.
Direct Connection to Water Supply/Drainage
No

Direct Connection to Water Supply/Drainage

The vacuum’s base connects directly to the home’s plumbing (like a washing machine). It automatically draws clean water for washing the mop pads and disposes of dirty water into the drain, completely eliminating the need to manually fill and empty water tanks. Note: Proper water supply and drainage installation is required at the place of setup.
