Robot with LiDAR and mop for 3,495 CZK. Alza's vacuum cleaner is half price

A robot with LiDAR navigation for under three and a half thousand is an offer that deserves attention – navigation is precisely what makes the difference between a vacuum cleaner that systematically cleans an apartment and one that blindly bumps into furniture. You can now buy the Siguro RV-R800B with code ALZADNY50 for 3,495 CZK instead of 6,990 CZK.

👍 Take it if you want a robot that vacuums and mops, navigates your apartment on its own, and you don’t have to deal with an English app.
🤔 Hesitate if you don’t want to empty the dustbin manually – this model doesn’t have a self-emptying station, and the container has a 500 ml capacity.
💰 Price: 3,495 CZK for LiDAR, 6,000 Pa, and a mop, with a three-year warranty from Siguro; an unboxed item costs 3,425 CZK.

LiDAR and camera that avoid cables

Essential equipment that cheaper robots lack: LiDAR navigation combined with a laser sensor, gyroscope, and binocular AI sensor. This allows the robot to create an accurate map of the apartment, move systematically, and thanks to obstacle recognition, it can avoid cables, shoes, or toys instead of pushing them around. It also works in the dark, so you can schedule cleaning when you’re not home.

The suction power of 6,000 Pa is above average for this price, and the robot is designed for pet hair and allergy sufferers thanks to the HEPA H13 filter, which captures dust mites and pollen. The 5,000 mAh battery lasts 253 minutes, which is over four hours, and when it runs out, it recharges and then continues where it left off. In addition to vacuuming, it also handles mopping thanks to a 270 ml water tank, and a virtual wall for defining areas is also included in the package.

For Czech users, two practical points: the robot speaks Czech and Slovak and is controlled via the extended Tuya Smart app, where you can set schedules and zones. And Siguro, as an Alza brand, provides a 36-month warranty, which is one year more than required by law.

Where are the compromises

A rating of 4.3 out of 5 from 53 customers is good, but not without flaws – and the limitations are dictated by the price. The biggest is the missing self-emptying station: you will have to manually empty the 500 ml dustbin, possibly after every cleaning in households with pets. Mopping is handled by a classic textile pad with a water tank, so expect maintenance mopping, not the removal of dried stains – for that, robots need rotating and heated mops from a price category twice as high.

The noise level of 70 dB is standard, but you won’t run it during home office, and it can handle obstacles up to 2 cm, so high thresholds or thick carpets can be an issue. One more detail from the parameters: both the app and the device start in English and must be switched to Czech, which surprises a few users initially. However, for 3,495 CZK, it is one of the best-equipped robots in this price range – mainly thanks to LiDAR and AI obstacle avoidance, which you won’t find elsewhere at this level. You can find other cleaning technology in Mega discounts at Alza.

Do you have a robotic vacuum cleaner at home? And does it reliably avoid cables in your place?
