TL; DR: Get them. I recommend purchasing these extra brush heads for almost any vacuum cleaner. I hate cleaning and these brushes can help me be more thorough and efficient. The results are better with these brushes than the ones that came with my vacuum. THE BRUSHES INCLUDED WITH THE VACUUM CLEANER ARE NOT GOOD The brushes that came with my vacuum cleaners (Shark and Dyson) are very hard and seem good for cleaning soft materials like upholstery. They don't clean hard surfaces like baseboards very well. For that I would use something like a crevice tool, which isn't really up to the job. THESE BRUSHES ARE AFFORDABLE AND DO THE JOB These brushes are soft and flexible so they scrub/wipe hard surfaces very well. This really eliminates the need for dusting or wiping with a rag. I vacuumed all of our trim (baseboards and crown molding), doors, windows and blinds. I used the second brush to clean the bathroom and toilet. Removing all of this dust reduces the time and energy it takes to clean these surfaces. These brushes were recommended by Go Clean Co which is definitely a great recommendation. Got a good deal at a very reasonable price.
