After having worked for a year. Excellent tool that performs its function admirably. Following the children's recommendation, I made the purchase, and now both of my children have a set. Under the current circumstances, purchasing a filter will be challenging; but, it is possible to clean it, etc., etc.; however, sooner or later, you will be need to purchase a new one. At the very least, pick some up while you're away. It is primarily used by my wife, while I rather like iRobot. Has some pros Lightweight, has a brush that illuminates surfaces with a laser, has enough battery capacity to clean an area of 76 m2, and has powerful dust-sucking capabilities. Its drawbacks include the absence of a maintenance description and the fact that shaking the dust collector is not an adequate method for cleaning it.
