Stains on the sofa, spilled drinks on the carpet or dirt in your car’s interior can be treated effectively with a suitable upholstery cleaner. However, not every appliance with a high wattage is automatically right for your home. The Deerma BY700 S carpet cleaner combines spraying, brushing and suction with hot-water and steam functions. The key question is whether its features, material compatibility and cleaning requirements suit the way you intend to use it.
As a Joybuy Product Recommendation Officer, I provide an objective assessment of the key product details and explain which choice may be suitable for different usage profiles.
The stated 1700 W for the Deerma BY700 S primarily describes its electrical power consumption. On its own, it does not indicate how much moisture the appliance removes from fabric. For practical assessment, the separately stated 13 kPa suction power is more relevant. You should also consider the design of the nozzle, the hose and whether you can move slowly over the treated area.
According to the product description, the Deerma BY700 S offers three modes: steam, hot water and room-temperature water. The specifications state up to 100 °C high-temperature steam and a 60 °C thermal rinse. This does not mean that every fabric can withstand these temperatures. Before use, check the care label and operating instructions, and test colourfastness and material compatibility on an inconspicuous area.
For delicate textiles, velvet, silk, coated surfaces or materials that are not suitable for wet cleaning, a suitable stain remover without a hot-water function may be the lower-risk option.
A self-cleaning function can flush residue from the hose and cleaning system. However, it does not replace emptying and rinsing both water tanks. If the dirty-water tank, brushes and filters are stored wet for prolonged periods, unpleasant odours may develop. After every use, removable parts should be cleaned and dried completely.
A carpet washer or wet vacuum cleaner should have separate clean- and dirty-water tanks. On the Deerma BY700 S, the clean-water tank holds 1.7 litres, while the dirty-water tank holds 1.4 litres. This prevents collected water from being returned to the clean-water supply. This capacity can be practical for families, pet owners and cleaning multiple upholstered surfaces.
Before buying, check whether both tanks are easy to remove and whether the maximum fill level is clearly marked. Cleaning products should only be used if they are approved for the appliance in question and produce as little foam as possible.
The stated 13 kPa suction power of the Deerma BY700 S is a technical comparison value within the product description. In practice, the amount of moisture left behind also depends on the nozzle, fabric structure, volume of water and working speed. After spraying, move the nozzle slowly over the area several times without dispensing additional water.
This is particularly important for mattresses, car seats and densely woven carpets. Too much liquid can extend drying times and cause problems with sensitive materials.
A good carpet washer should be suitable for more than just large carpeted areas. The Deerma BY700 S comes with a 5-in-1 brush set. Depending on the attachment, the appliance can be used on carpets, sofas, stairs, mattresses and car seats. Even so, check whether the nozzle is narrow enough for slim stair treads or confined areas inside a vehicle.
A steam cleaner for textiles works with heat, while a fabric cleaner with spray and suction functions collects liquid together with loosened dirt. These appliance categories are not equally effective for every application.
Why this product suits this profile: This compact, portable appliance is designed for individual stains, stairs, upholstery and car interiors. It is suitable for households looking for a space-saving appliance for occasional use.
The product description highlights its compact dimensions and low weight rather than making an unsupported claim about area coverage. No hot-water function is specified.
Spray, brushing and suction functions; suitable for stairs, upholstery and vehicle interiors.
Why this product suits this profile: The combination of 1700 W, 13 kPa suction power, separate tanks and three water modes is suitable for households dealing with recurring stains on various water-resistant textiles.
The technical specifications distinguish between power consumption and suction power. Fresh and dirty water are also kept separate, with capacities of 1.7 and 1.4 litres respectively.
Three cleaning modes; 5-in-1 brush set; self-cleaning function; IPX4 water-resistance rating.
Why this product suits this profile: This appliance is designed for carpets, sofas, stairs and car seats, and offers two cleaning modes. That makes it appealing to users who regularly clean different textile surfaces.
The description specifies separate tanks with capacities of 1.6 and 0.95 litres, as well as a 40 °C heating function. This gives the temperature specification a clearer context than a generalised steam claim.
Two cleaning modes; 1.8 m hose; hose-cleaning attachment; separate water tanks.
We have put together a complete, regularly updated list of products that fully meet these strict selection criteria and the safety regulations applicable in the EU.
Appliances with steam or hot water must not be directed at people, animals, electrical appliances or delicate surfaces. An IPX4 rating does not indicate protection against submersion. Always follow the manufacturer’s instructions and the textile’s care label.
According to the product description, the appliance is designed for several textile surfaces and is therefore also intended for car interiors. Before use, check whether the seat fabric can be wet-cleaned. Electrical seat components, controls and delicate leather surfaces must not be treated with water or steam.
The dirty-water tank should be emptied and rinsed after every use. Brushes, filters and the hose should also be cleared of residue and dried completely. The self-cleaning function can support this process, but it does not replace manual inspection.
The stated power of 1700 W corresponds to 1.7 kW during operation. Actual consumption depends on how long the appliance is used and which mode is selected. With 30 minutes of operation, the calculated consumption is approximately 0.85 kWh. To calculate the running cost, multiply this figure by your current electricity price.
