Cylinder vacuum ROWENTA Compact Power RO3731 — 750 W, Dry, Bagless 1.5 L, Foam + HEPA filtration

ROWENTA Compact Power RO3731 is a compact cylinder vacuum cleaner designed for home use. With a maximum input power of 750 W, dry cleaning mode, and a 1.5 L bagless dust container using cyclonic separation, it provides straightforward cleaning for bare floors, hard floors and carpets. Filtration combines a foam pre-filter and a HEPA filter to reduce airborne dust and particles during operation. The unit is available in black and blue and weighs approximately 6.38 kg.

Advantages

The vacuum’s cyclonic system maintains suction performance by separating larger debris from fine dust before it reaches the filters. The bagless 1.5 L dust container is easy to empty and reduces ongoing consumable costs. Combined foam pre-filter and HEPA filtration improves particle capture for cleaner exhaust air compared with basic filter setups. At 750 W maximum input power the cleaner offers an effective balance of suction and energy consumption for everyday home cleaning.

Suitable for

When it may not be suitable

This model is intended for dry cleaning only and is not suitable for wet spills or liquid pickup. Its 1.5 L dust container is appropriate for typical household use but will require more frequent emptying in larger homes or in environments with heavy shedding pets. The unit’s maximum input power and single-motor design may not match the deep-cleaning performance of larger, professional-grade machines on heavily soiled carpets.

Key specifications

How to use

Assemble the recommended nozzle and extension tube for the surface to be cleaned. Start the vacuum on the appropriate power setting and guide the nozzle slowly across the floor or carpet to allow the cyclonic system to separate debris effectively. Empty the 1.5 L dust container into a bin when the fill level approaches the marked maximum, and check or clean the foam pre-filter periodically to maintain airflow. Replace or clean the HEPA filter according to the manufacturer’s maintenance recommendations to preserve filtration performance.

What to consider before purchase

Recommendations

For best results on mixed surfaces, use the appropriate floor head for hard floors or carpets, empty the dust container regularly, and keep the pre-filter and HEPA filter clean according to the maintenance schedule to sustain suction and air quality.
