I bought this vacuum cleaner to use around the house to remove cat litter, cat food and other debris. I have had Shark vacuums before and their suction power is always excellent, but the suction power on this little vacuum is not what I expected from a Shark product. It doesn't have enough suction power to suck individual small bits of cat food into the container, rather the cat food stays inside the stick and falls back to the floor once the vacuum is turned off. I completely disassembled it…
