dense fabric furniture is difficult to vacuum without swearing, because with strong traction, the vacuum cleaner automatically turns off and then turns off again, which is not very useful for it. thus, dense upholstery and bedspreads are difficult to clean with this nozzle (although, if compared with the original motorized furniture brush, during cleaning, if a certain traction force is exceeded, the vacuum cleaner turns off and does not start again + tends to chew the bedspreads). less dense fabrics that are well breathable (both in upholstery format and in the format of bedspreads, curtains, etc.) can be cleaned without the above problem.
