I recommend storing the vacuum cleaner in a horizontal or strictly vertical position and avoid bending during storage. Has pros: We have been using it for more than a year and a half, there are no complaints about the work. Great vacuum cleaner for the money. Ideal for cleaning carpet from wool and hair, it feels better than a conventional vacuum cleaner. Got cons: Not suitable for cleaning up large pieces of debris (cat litter, large crumbs), but apparently this is a common problem with upright vacuums.
