Input:
I'm very pleased with this vacuum for a number of reasons, including its affordable price, portability, and adaptability. Prospective purchasers should be aware, however, that this is not a heavy-duty cleaner. I have a studio apartment with less than 500 square feet of carpeting, and a very small kitchen and bathroom. This vacuum works well on the standard cheap apartment carpet, my area rugs, and the linoleum, but would be far too much work for larger areas. The floor head is small and does not have a rotating beater brush and the ring which controls the air flow can be tricky as it doesn't lock into position. For small spaces, however, especially for one person without furry pets, this is just fine. The cord is a good length, the vacuum is light, it reaches pretty much anywhere, and the bag is easily replaced.
