Kärcher SG 4/4 Industrial Steam Cleaner
£962.00(£1,154.40 inc VAT)
Delivery Information
Price Match
The Kärcher SG 4/4 is a professional-grade steam cleaner designed for continuous use in commercial environments. It produces high-temperature steam to break down grease, carbonised residue, and general soiling across a wide range of kitchen surfaces — without relying on chemical cleaning agents. That makes it a practical choice for operators working in food-safe environments where chemical residue is a concern or where cleaning product usage needs to be minimised.
The twin-tank design is the key feature that sets this unit apart from simpler steam cleaners. One tank heats while the other feeds steam, meaning the unit can be topped up during operation rather than having to be shut down and allowed to cool. In a commercial kitchen environment, that translates to uninterrupted cleaning sessions — useful during daily deep cleans or end-of-service routines where downtime needs to be kept short.
In day-to-day kitchen use, the SG 4/4 is commonly applied to oven interiors, griddle surfaces, extraction canopies, tile grout, drain channels, and equipment frames — areas where conventional cleaning is time-consuming or where chemical use is restricted. Key operational advantages include:
- Chemical-free cleaning suitable for food contact surfaces and food preparation areas
- Continuous operation with no enforced cool-down period between refills
- Effective on heavy grease deposits, baked-on residue, and general kitchen soiling
- Reduces reliance on chemical cleaning agents, lowering consumable costs over time
- Broad surface compatibility across stainless steel, tile, grout, and sealed flooring
This is a mains-powered unit intended for fixed or semi-fixed use. A trolley accessory is available separately, which improves mobility across larger kitchen floors and provides a practical storage solution for the hose and accessories between uses. It is worth confirming that your site has a suitable power supply and accessible water fill point before purchasing.
The SG 4/4 is well suited to medium-sized commercial kitchens, restaurant operations, and contract catering sites where regular deep cleaning is part of the maintenance routine. It is particularly appropriate where there is a preference for reducing chemical use. For very high-frequency use across large multi-kitchen sites, a heavier-duty model in the Kärcher range may be worth considering.
If you are unsure whether this model is the right fit for your cleaning regime or kitchen size, our team is happy to talk it through with you before you place an order.
Frequently asked questions
Can the SG 4/4 be used on food contact surfaces without chemical concerns?
Yes — because the unit cleans using steam rather than chemical agents, it is generally well suited to food contact surfaces, cooking equipment interiors, and preparation areas where chemical residue is a hygiene concern. As with any cleaning process, surfaces should be checked against your kitchen's hygiene protocols and the equipment manufacturer's guidance.
Does the unit need to cool down before it can be refilled with water?
No. The twin-tank design means one tank is always in reserve, allowing the unit to be topped up during use without needing to stop and cool down first. This is particularly useful in busy kitchens where cleaning windows are limited.
Is the SG 4/4 suitable for large multi-kitchen or contract catering sites?
It is a capable unit for regular commercial kitchen deep cleaning, but for very high-frequency use across large or multi-site operations, it would be worth speaking to us about whether a heavier-duty model in the Kärcher range would provide better durability and throughput for your specific workload.
