Robotic Vacuum Cleaner S3 PRO Blue - 4,000Pa LiDAR Navigation

In this review the TECBOT S3 PRO Robotic Vacuum Cleaner and mop is assessed for busy households that need reliable daily floor care; the bottom line is that it is best for homes with hard floors and pets because its strong suction and tangle-resistant brushes remove hair and debris with minimal intervention. The review finds the S3 PRO delivers consistent results thanks to its 4,000 Pa suction, long battery life, and intelligent navigation, making it a practical choice for people who want one device to sweep, vacuum and mop while they focus on other tasks.

Key Features

• Powerful Suction: Up to 4,000 Pa suction lifts dust, crumbs and pet hair from hardwood and low-pile carpets for noticeably cleaner floors.
• 5200mAh Battery: A large battery provides up to 150 mins runtime so the robot can clean most homes without repeated charging.
• 360 LiDAR Navigation: LiDAR mapping creates accurate floor plans and supports No-Go zones so fragile areas are avoided during cleaning.
• Obstacle Avoidance: Front triangular sensors and anti-fall protection let the robot detect and steer clear of obstacles and stairs for safer operation.
• Dual Rubber Brushes: Multi-surface rubber brushes adapt to floor transitions and resist tangles from pet hair for lower maintenance.
• App and Voice Control: Tuya Smart App, Alexa and Google Assistant support lets users schedule, change modes and control the robot remotely.

Who It's For

The S3 PRO is ideal for pet owners and families with mostly hard floors or low-pile rugs who want automated cleaning that handles hair and everyday debris without constant supervision. Its strong suction and tangle-resistant brushes make it a good fit where pet hair is a recurring issue.

It is less well suited for homes with high-pile carpets or very cluttered rooms where manual pre-tidying would still be required; users who need deep carpet cleaning or specialized high-pile performance should consider a different model designed specifically for thick rugs.

Pros & Cons

Pros

• Strong 4,000 Pa suction cleans dust and pet hair effectively across hard floors and low-pile carpets.
• Long 5200mAh battery enables longer continuous cleaning sessions, often covering an entire floor in one run.
• Accurate 360 LiDAR mapping and No-Go zones let the robot avoid fragile areas and follow an efficient path.
• Dual rubber brushes reduce tangles from pet hair and work across multiple surfaces.

Cons

• Interchangeable mop and 240ml water tank are practical but may require refilling for larger mop jobs.
• Performance on high-pile carpets is limited compared with upright vacuums designed for thick rugs.

Specifications

Our Verdict

The TECBOT S3 PRO is a strong choice for households that need automated, low-maintenance cleaning on hard floors and low-pile carpets; its combination of 4,000 Pa suction, reliable LiDAR mapping and long battery life makes it good value for pet owners and busy homes.
