Proscenic 850T — LiDAR Robot Vacuum

Proscenic 850T: Full Review 2026

The Proscenic 850T is the robot vacuum that brings LiDAR navigation within reach of everyday budgets. As the first Proscenic model fitted with a genuine laser-mapping sensor, it pairs 3,000 Pa of suction with 120 minutes of runtime and a passive mopping function for thorough whole-home cleaning. Backed by more than 1,800 customer reviews and a 4.3/5 rating, the Proscenic 850T has earned its reputation as the benchmark LiDAR robot vacuum cleaner under 200 GBP.

Design and form factor

The Proscenic 850T follows the familiar circular shape at 33 cm in diameter with a height of just 97 mm. That low profile lets it slip beneath most sofas, beds and low-standing furniture with ease, cleaning areas a traditional vacuum simply cannot reach. On top sits the slightly protruding LDS/LiDAR turret, a visible indicator of the navigation technology inside. Matte black plastic finishes give the robot a clean, modern look that blends unobtrusively into any room. The 500 ml dustbin is accessed from the top and lifts out in a single motion for quick emptying. At the rear, the 300 ml water tank feeds the passive mopping system through a microfibre pad clipped to the underside. The Proscenic 850T weighs roughly 3.5 kg, standard for its class, and the compact charging dock occupies minimal floor space.

Vacuuming and mopping performance

At 3,000 Pa of suction, the Proscenic 850T sits comfortably above the average for mid-range robot vacuums. Several cleaning modes are on offer — Quiet, Standard, Strong and Max — letting you tailor power to the floor type and soil level. Automatic carpet detection is a genuine standout feature: the moment the robot senses a textile surface, it ramps up suction to dislodge embedded dirt from the pile, then drops back to normal on hard floors. This cleaning intelligence ensures thorough results without manual intervention. The mopping system is passive in nature: a dampened cloth fed by the 300 ml tank is dragged behind the robot as it vacuums. It is not an active-scrubbing mechanism, but the damp pass is effective at picking up residual fine dust and freshening hard floors between manual cleans. Noise sits at a contained 65 dB in standard mode, making it easy to schedule sessions without disturbing anyone at home.

Battery life and charging

The Proscenic 850T delivers 120 minutes of runtime in standard mode, enough to cover between 150 and 200 m² on a single charge. For larger homes the robot offers automatic recharge-and-resume: when battery drops to a critical level, it returns to the dock on its own, tops up, then picks up cleaning exactly where it left off. A full charge takes approximately 4 to 5 hours. This runtime-plus-resume logic ensures every corner is reached even in the most spacious properties.

Navigation and mapping

It is the LDS/LiDAR navigation that fundamentally sets the Proscenic 850T apart from entry-level robots relying on gyroscopic steering. The rotating laser sensor takes 2,160 measurements per second across a full 360 degrees, building an accurate map of your home. The robot then follows methodical parallel-line paths rather than bouncing around randomly, which translates into faster, more thorough cleaning with fewer missed spots. Multi-floor mapping lets you save layouts for several storeys and switch between them in the Proscenic Home app. Through the app you can also draw no-go zones and virtual walls to keep the robot away from specific areas — pet bowls, speaker cables or children's play corners. Scheduling rounds out the feature set: programme recurring cleaning sessions for every day of the week. The Proscenic 850T is also compatible with Alexa, Google Home and Siri, so you can kick off a clean with a quick voice command.

Maintenance and accessories

Looking after the Proscenic 850T is straightforward. The 500 ml dustbin empties easily and the filter is washable under running water for extended reuse. The main brush should be cleared of accumulated hair and fibres on a regular basis. The mopping pad detaches and is machine-washable. Proscenic supplies replacement side brushes and filters as accessories. The robot is covered by a 2-year manufacturer warranty with European after-sales support.

Our verdict

The Proscenic 850T is the smartest pick for anyone keen to experience LiDAR navigation without stretching the budget. It delivers features usually reserved for far pricier robot vacuums — multi-floor mapping, no-go zones, carpet detection, voice control — all at a mid-range price. If you do not need a self-emptying base, the 850T is hard to beat at this price point. For those who want the convenience of automatic emptying, the Q8 Max remains our recommendation.
