Best carpet cleaners: tested and reviewed by Which? experts

The article evaluates various carpet cleaners to help consumers make informed purchasing decisions, emphasizing that a quality carpet cleaner can rejuvenate carpets. It advises considering factors beyond cleaning performance, such as size, portability, and specific features, as these machines can be substantial investments. The piece notes that some models are large and difficult to store or move upstairs, while others offer specialized features for routine cleaning or tough spills. Given the potential cost, understanding useful features is crucial. Which? experts conduct independent laboratory tests focusing on key performance indicators. The primary assessment involves how effectively cleaners refresh tired and grimy carpets. This is measured by cleaning and drying three soiled carpets, then using a spectrometer to quantify dirt removal and brightness improvement. The tests also examine how closely each cleaner works to carpet edges for uniform results. A visual comparison illustrates the difference between uncleaned carpets and those treated by one-star and five-star rated cleaners. Another critical test evaluates the cleaners' ability to remove dried-on stains. Carpet samples are stained with red wine, coffee, and mud, left to dry for 24 hours, and then cleaned according to manufacturer instructions. The effectiveness of stain removal is subsequently assessed. The findings indicate that most carpet cleaners are not highly effective against dried-on stains, suggesting that dedicated carpet stain remover sprays are generally more suitable for such tasks. Water retention is also a significant factor. The article explains that some carpet cleaners leave carpets excessively wet due to inefficient dirty water extraction. To measure this, carpet samples are weighed before cleaning and then at one, five, and 24 hours post-cleaning to determine the amount of residual water. A higher rating indicates a drier carpet after cleaning. Ease of use and noise levels are evaluated by a panel of three experts. They assess how noisy the cleaner is and whether the sound is intrusive. Usability factors include cord and nozzle length, water tank capacity and leak resistance, machine weight, ease of assembly and maneuverability, and clarity of instructions. Which? regularly updates its testing to include popular new models. The article clarifies the distinction between standard carpet cleaners and spot cleaners. Standard carpet cleaners are typically bulky machines designed for extensive areas, while spot cleaners are smaller, compact devices intended for localized stains and spills. Despite their purpose, recent tests on spot cleaners from brands like Karcher, Shark, and Vax yielded underwhelming results, particularly for coffee stains, leading to a general recommendation against them. The article also addresses the use of steam cleaners on carpets, advising caution due to the risk of shrinking or damaging carpet fibers if used improperly or for too long, concluding that dedicated carpet cleaners are preferable. For those seeking to deep clean carpets without specialized machines, the article offers DIY tips. It recommends starting with thorough vacuuming, then addressing visible stains with either a dedicated remover or a homemade solution. Important advice for stain removal includes acting quickly, removing excess spill, working from the stain's outer edges inward, testing cleaning products on an inconspicuous area, and avoiding excessive or hot water, which can worsen stains. After stain treatment, sprinkling baking soda, a natural deodorizer, can absorb odors; it should be left for at least 15 minutes before vacuuming. The article reinforces its editorial independence, stating that its evaluations are not influenced by product manufacturers or retailers. #CarpetCleaners #HomeCleaning #ProductReviews #StainRemoval #WhichTests #DeepCleaning #HomeMaintenance #ApplianceReviews #CarpetCleaners #HomeCleaning #ProductReviews #StainRemoval #WhichTests #DeepCleaning #HomeMaintenance #ApplianceReviews
