A robotic vacuum cleaner from a Czech brand has significantly dropped in price. It features LiDAR, decent performance, and can be connected to a mobile phone

You can now get a robotic vacuum cleaner from a Czech brand at a significant discount. The TESLA RoboStar iQ900 Ultra is now available from 8,698 CZK, which represents a drop of over 2,000 CZK compared to its launch price in December. It combines vacuuming and mopping functions, boasts an automatic docking station, and relies on LiDAR technology for navigation.

Quick Summary:
✅ Makes sense if you’re looking for a comprehensive cleaning solution with an automatic station that washes and dries mops, and you appreciate Czech localization.
⚠️ Consider carefully if you have exclusively high-pile carpets or need to overcome thresholds higher than 1.5–2 cm.
💡 For a price under 9,000 CZK, you get features that competitors often offer starting from 12–15 thousand – automatic hot water mop washing, drying, and dirt disposal.

What it can do and why it’s interesting

The TESLA RoboStar iQ900 Ultra belongs to the category of 4-in-1 robotic vacuum cleaners – it vacuums, mops with rotating brushes, automatically washes and dries mops, and disposes of dirt into the station. In practice, this means you don’t have to manually clean the mop pads or empty the dustbin after cleaning. The station contains large tanks for clean and dirty water (4.6 liters each) and a dirt bag with a capacity of 3 liters, which lasts up to 3 months.

An interesting feature is the innovative extendable rotating mop arm, which can extend sideways to reach along walls, around furniture, and into corners. Most competitors in this price range do not offer this feature – mops remain under the robot’s body, leaving room edges untouched.

Navigation and Suction Power

The robot uses 360° laser LiDAR navigation in combination with a Line laser for obstacle detection. This ensures systematic cleaning without random wandering and precise home mapping. In the TESLA Smart app, you can store up to 5 maps (ideal for multi-story homes), set 14 forbidden zones, and 20 virtual walls.

The digital BLDC motor offers 10,000 Pa suction power, which is a solid value for this price category. When moving onto a carpet, the robot automatically increases suction power and lifts the mops by 1.5 cm to prevent wetting the fibers. The 5,200 mAh battery lasts up to 168 minutes on a single charge in eco mode – sufficient even for larger apartments or family homes.

Automatic Station and Maintenance

The multifunctional station is the main attraction of this model. After cleaning, the robot returns to the station, which automatically washes the mops in warm water with detergent, then dries them with hot air (which reduces mold and odor formation), and empties dirt from the dustbin into a bag. The station has its own detergent tank with a volume of 400 ml.

Filtration uses a double system with a foam filter and a washable HEPA H13 filter, which captures at least 99.95% of particles as small as 0.3 micrometers – including pollen, bacteria, and allergens. This is especially beneficial in homes with allergy sufferers or pets.

Czech Localization and Control

The robot speaks Czech (as well as Slovak, Polish, Hungarian, Romanian, English, and German) and the TESLA Smart app is fully localized into Czech, including technical support in the Czech Republic. In the app, you can set 4 levels of suction power, 3 levels of water flow during mopping, and 5 cleaning modes. Compatibility with Amazon Alexa and Google Assistant is also included.

Cleaning scheduling is flexible – you can set a weekly schedule with specific times for individual days. The robot also works without an internet connection if you prefer offline operation.

What Users Say

On the official TESLA e-shop, the vacuum cleaner currently has 12 ratings, and users are mostly satisfied. They primarily praise the comprehensiveness of the solution – “all-in-one, worry-free”, quiet operation, and the fact that the robot truly reaches the edges of rooms. Several reviews mention that the vacuum cleaner “even earned a name and is a welcome member of the household”.

Critical voices appear regarding occasional Wi-Fi connection issues – some users report that the robot has difficulty picking up a signal in the back parts of the apartment. Another mentioned problem concerned water usage – original instructions recommended distilled water, which led to error messages. The manufacturer has since updated the recommendation: regular drinking water or a mixture with distilled water in a 1:3 to 1:1 ratio can be used in the tank.

On Alza, the model currently has only 2 ratings with an average of 2.5 out of 5, but with such a low number of reviews, it’s difficult to draw conclusions. After product registration, a 3-year extended warranty can be obtained for free.

When it doesn’t make sense

If you have high thresholds or obstacles over 2 cm in your apartment, the robot will likely not overcome them – the manufacturer states a limit of around 1.5–2 cm. Similarly, if you have exclusively high-pile carpets with long fibers, the mopping function will not be fully utilized, and the robot may have difficulty moving. For homes with waxed parquet floors, the manufacturer recommends using mopping very carefully or not at all – wax can be sensitive to moisture.

If this particular model didn’t appeal to you, but you’re looking for a robotic vacuum cleaner with an automatic station, you might consider alternatives like the Roborock Q10 VF+ or Xiaomi Robot Vacuum X20 Pro in a similar price range.

Verdict: Who it’s worth it for

If you’re looking for a comprehensive robotic vacuum cleaner with an automatic station that washes and dries mops, the TESLA RoboStar iQ900 Ultra, priced from 8,698 CZK, offers features that competitors often sell for significantly more. Czech localization, the extendable mop arm, and automatic hot water washing are above average in this price range. Conversely, if you have a complex apartment with high thresholds or prefer premium brands with a longer market history, you might want to consider more expensive alternatives.

Do you use a robotic vacuum cleaner with mopping, or is classic vacuuming enough for you?
