A carpet cleaner should remove stains, collect dirty water and make textiles usable again as quickly as possible. The Deerma BY700 S carpet cleaner offers features such as hot water, steam, separate water tanks and a stated suction power of 13 kPa. However, technical figures alone do not determine whether a device is practical for your home.
Families with children, pet owners and car owners should pay particular attention to three common pitfalls before buying:
A suitable carpet washer combines three stages: cleaning solution or water is applied, the fabric is worked with a brush and the loosened liquid is then vacuumed up. This combination is useful for spot-treating carpets, sofas, chairs and car seats.
Look for:
A spot cleaner with only a small nozzle is mainly suitable for individual areas. If you regularly want to clean a sofa, treat several carpets or clean car seats, you will benefit from multiple attachments and sufficient hose reach.
The specification 13 kPa suction power describes the negative pressure a device can generate under certain conditions. It is a technical comparison value, but not proof of quality on its own. Actual moisture collection also depends on the nozzle, air path, filter condition and the speed at which the nozzle is moved across the fabric.
According to the product information, the Deerma BY700 S is specified with 13 kPa suction power, a motor suction power of 400 W and a rated power of 1700 W. In practical terms, this means making several slow suction passes after washing, while avoiding prolonged water application to delicate textiles.
Separate fresh- and dirty-water tanks prevent water that has already been collected from being returned to the surface. The Deerma BY700 S has a 1700 ml fresh-water tank and a 1400 ml dirty-water tank. Before each use, check the textile’s care label and test the device on an inconspicuous area.
It is also important to:
A steam carpet cleaner is therefore not automatically suitable for every surface. For delicate textiles, a room-temperature or hot-water function may be the more appropriate choice.
The following recommendations classify the devices according to specific requirements. Technical details are taken from the respective product information.
Why this product suits this profile: This compact upholstery cleaner is designed for occasional stains on carpets, sofas, mattresses and car seats.
The 3-in-1 system combines spraying, brushing and suction. The 1.5-litre fresh-water tank and 0.8-litre dirty-water tank keep the two water circuits separate.
The stated specifications include 15 kPa suction power, a 4.26-foot hose and a 9.84-foot power cable.
Why this product suits this profile: For households looking for a corded carpet washer with several water and cleaning modes.
The separate tanks and three modes for steam, hot water and room-temperature water allow you to choose the most suitable option for the task. Material compatibility must still be checked beforehand.
The stated specifications include 1700 W rated power, 13 kPa suction power, a 1.7-litre fresh-water tank and a 1.4-litre dirty-water tank.
Why this product suits this profile: This device is aimed at users who want to repeatedly clean carpets, upholstery and vehicle interiors with a specialised attachment.
The XL brush and 15 cm cleaning head are designed for different surfaces. However, this does not replace checking the care instructions for the material in question.
According to the product information, the model has 750 W motor power, a 1.5 m hose and a tank system with a total capacity of 2.8 litres.
Why this product suits this profile: As a dry mattress cleaner, this device is suitable for beds, sofas and textile surfaces when wet cleaning is not wanted.
The device works without fresh- and dirty-water tanks. This removes the risk of over-wetting mattresses through wet cleaning.
The stated specifications include 300 W, 12 kPa suction power, a 300 ml dust container, UV-C light, 65 °C warm air and a 5 m cable.
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.
A carpet or upholstery cleaner uses electricity, water and, where applicable, cleaning products. With a corded 1700 W carpet cleaner, electricity consumption depends on the operating time: one hour of continuous operation corresponds to 1.7 kWh in theory, although the actual figure may vary depending on the operating mode. For individual stains, a short treatment is usually more resource-efficient than a full wet clean.
After each use, clean the tanks, brushes and hoses. If you skip this maintenance, you risk build-up, odours and declining suction performance. With normal household use, the number of months is less important than proper handling, dry storage and the availability of replacement filters or accessories.
According to the product description, the device is intended for various textile surfaces and comes with several brush attachments. Before use, check the care label, colour fastness and moisture resistance on an inconspicuous area. For car seats, adequate ventilation is also necessary so that the upholstery can dry completely.
No. The steam function should only be used if the manufacturer of the material being cleaned permits it. Delicate fabrics, leather, coated surfaces and bonded materials may react to high temperatures. If in doubt, the water function with a lower temperature is the safer option.
A fixed service life cannot be inferred from wattage or suction power. Regular rinsing, thorough drying, emptying the tanks and observing the maximum fill levels all support trouble-free operation. Before buying, it is worth checking the warranty, spare parts and the manufacturer’s cleaning instructions.
