STI Comby 3500 Dry Steam & Vac

The STI Comby 3500 Dry Steam & Vac is a high-performance, dual-function dry steam cleaner and vacuum system designed for demanding commercial and industrial cleaning tasks. As a more powerful upgrade to the Comby 3000, the Comby 3500 delivers increased steam pressure, higher temperature output, and larger tank capacities — making it ideal for commercial kitchens, food production sites, healthcare facilities, automotive detailing, engineering workshops, and contract cleaning teams.

Operating at 8 bar pressure and 180°C dry steam temperature, the Comby 3500 provides exceptional cleaning and sanitising performance. The high-temperature steam cuts through grease, oils, limescale, carbon deposits, bacteria, and embedded dirt with ease. Meanwhile, the integrated vacuum extraction system removes loosened residues, debris, and moisture instantly, leaving surfaces cleaner and drier with no need for manual wipe-down after steaming.

Designed for continuous operation, the machine features a large 5-litre water refill tank, allowing users to top up the system without shutting it down. The additional 5-litre detergent tank enables detergent injection directly into the steam line for enhanced cleaning power during heavy-duty applications.

Powered by a robust 3000 W heating system, the Comby 3500 ensures fast heat-up times and consistent steam output, even during prolonged use. Supplied with a complete professional Comby tool kit, operators are equipped with everything required for floors, upholstery, kitchens, washrooms, machinery, vehicles, and precision detail cleaning.
