Russell Hobbs RHC940 Steam Iron Specs, Use & Buying Advice

The Russell Hobbs RHC940 is a 2400-watt steam iron with a 300-milliliter water tank, a ceramic soleplate, and a variable steam output of up to 40 grams per minute. You enter your fabric type and desired steam level, and the iron delivers consistent heat and steam for wrinkle-free results on most garments. This article covers its full specifications, how to use it effectively, what to look for when buying, and answers to common questions.

Formula

The calculator estimates water consumption and steam burst count based on ironing time and steam setting. The formula assumes an average steam rate of 10 ml per minute on low, 20 ml on medium, and 30 ml on high. Water used (ml) = time (min) × steam rate (ml/min). Steam bursts (count) = time (min) × burst rate (bursts/min), where burst rate is 2 bursts per minute on low, 4 on medium, and 6 on high.

Worked Example

Using the default values: time = 30 minutes, steam setting = medium (2). Steam rate = 20 ml/min. Water used = 30 × 20 = 600 ml. Burst rate = 4 bursts/min. Steam bursts = 30 × 4 = 120 bursts. The calculator shows 600 ml and 120 bursts.

Full Specifications of the RHC940

The Russell Hobbs RHC940 is a mid-range steam iron designed for home use. Key specifications include:

• Power: 2400 watts
• Water tank capacity: 300 ml
• Soleplate: Ceramic (non-stick, glides smoothly)
• Steam output: Up to 40 g/min (variable)
• Steam burst: 150 g/min (for vertical steaming)
• Spray function: Yes, fine mist
• Anti-drip: Yes, prevents water spots
• Self-cleaning: Yes, with anti-scale function
• Cord length: Approximately 2.5 meters
• Weight: About 1.2 kg

These specs are typical for a 2400W iron; actual performance may vary slightly by region (e.g., 220-240V). The ceramic soleplate distributes heat evenly and resists scratches better than stainless steel.

How to Use the RHC940 Effectively

Using the RHC940 is straightforward, but following these steps ensures best results:

1. Fill the water tank with clean tap water (or distilled if you have hard water). Do not exceed the MAX line.
2. Plug in and set the temperature dial according to fabric type: low for synthetics, medium for wool, high for cotton/linen.
3. Wait for the soleplate to heat up (the indicator light turns off when ready).
4. Select steam level: low for delicate fabrics, high for thick cotton. Use the steam burst button for stubborn wrinkles or vertical steaming.
5. Iron in straight strokes, applying even pressure. For delicate fabrics, use a pressing cloth.
6. After use, empty the water tank and let the iron cool before storing.

Always check the garment care label first. Some fabrics (silk, velvet) require dry ironing or a low temperature.

Buying Advice: What to Look For

When considering the RHC940 or any steam iron, evaluate these factors:

• Wattage: Higher wattage (2400W) heats up faster and maintains temperature better. For occasional use, 1800W is sufficient.
• Soleplate material: Ceramic and titanium glide best; stainless steel is durable but can stick. Non-stick coatings wear over time.
• Steam output: For heavy wrinkles, look for at least 30 g/min continuous steam and 150 g/min burst.
• Water tank capacity: 300 ml is average; larger tanks (350-400 ml) reduce refill frequency but add weight.
• Anti-drip and anti-scale: Essential for preventing water spots and prolonging iron life, especially in hard-water areas.
• Cord length and swivel: A 2.5m cord with a 360° swivel base improves maneuverability.
• Weight: Heavier irons (1.2-1.5 kg) press better but tire your hand. Consider your ironing volume.

If you iron frequently or have large laundry loads, a higher-end iron with more steam power may be worth the extra cost. For occasional use, the RHC940 is a solid mid-range choice.

Common Problems and Troubleshooting

Users may encounter these issues with the RHC940:

• Water leaking from soleplate: Usually because the iron isn’t hot enough or the tank is overfilled. Wait for the temperature to stabilize and reduce water level.
• White spots on clothes: Mineral deposits from hard water. Use distilled water or run the self-clean function.
• Iron not heating: Check the power cord, outlet, and thermostat. If the indicator light doesn’t come on, the heating element may be faulty.
• Steam not coming out: The steam vents may be clogged. Use the self-clean function or a cotton swab to clear them.
• Soleplate scratches: Avoid ironing over zippers or buttons. Use a protective soleplate cover when storing.

If the iron still malfunctions, contact Russell Hobbs customer support or a qualified technician. Do not attempt to disassemble the iron yourself.

Comparison: RHC940 vs. Other Irons

Compared to budget irons (1500-1800W, aluminum soleplate), the RHC940 offers:

• Faster heat-up and more consistent temperature
• Better glide due to ceramic soleplate
• Higher steam output for tougher wrinkles
• Anti-drip and self-clean features

Compared to premium irons (3000W, steam stations), the RHC940 is:

• More affordable and portable
• Easier to store and handle
• Less continuous steam (40 vs. 120 g/min)
• Smaller water tank (300 ml vs. 1.5 L)

For most households, the RHC940 strikes a good balance between performance and price. If you iron in bulk or have heavy fabrics, a steam generator might be better.

Safety Tips and Maintenance

To ensure safe and long-lasting use:

• Always unplug the iron when filling or emptying the water tank.
• Never leave a hot iron unattended, especially near children or pets.
• Keep the cord away from the hot soleplate.
• Use the self-clean function every 10-15 fills to remove scale.
• Empty the water tank after each use to prevent leaks and mineral buildup.
• Store the iron upright on its heel, with the cord loosely coiled.

If you have hard water, consider using distilled water to reduce scale. Do not use chemical descalers unless specified by the manufacturer.

Frequently Asked Questions

Can I use tap water in the RHC940?

Yes, tap water is fine in most areas. If you have very hard water, mix 50% distilled with 50% tap water to reduce mineral buildup. Avoid using 100% distilled water as it can cause spitting in some irons.

How do I clean the soleplate?

Unplug the iron and let it cool. Wipe the soleplate with a damp cloth and mild soap. For stubborn residue, use a paste of baking soda and water. Do not use abrasive scrubbers.

What does the anti-drip system do?

It prevents water from leaking out of the soleplate when the temperature is too low. This is especially useful when ironing delicate fabrics at low heat.

Can I use the steam burst for vertical steaming?

Yes, the steam burst button can be used to steam hanging garments or curtains. Hold the iron close to the fabric and press the burst button. Be careful not to touch the hot soleplate.

How often should I use the self-clean function?

Every 10-15 tank refills, or once a month if you iron frequently. Fill the tank to MAX, set the iron to high, and press the self-clean button. The iron will flush out scale and debris.

Is the RHC940 suitable for heavy fabrics like denim?

Yes, the high temperature and steam output handle denim well. Use the highest heat setting and a bit of steam. For thick seams, use the steam burst to relax the fibers.
