Household cleaning tools are often designed to be multifunctional and able to cope with different cleaning tasks. For example, a cleaning brush may be able to scrub surfaces as well as scrape away dirt, providing a more comprehensive cleaning solution. Modern household cleaning tools are ergonomically designed to be more comfortable and easier for the user to manoeuvre. The design of the grip, weight distribution and ease of operation are all examples of ergonomic design. Durability is one of the most important features of cleaning tools as they are often exposed to a variety of dirt and usage scenarios. High-quality materials and sturdy construction allow these tools to withstand frequent use and cleaning, maintaining a long service life. Since the cleaning tools themselves need to be kept clean and hygienic, they are usually designed with an easy-to-clean construction. Some tools have removable parts that can be easily cleaned to prevent residual dirt from affecting the next use.
