[Sorry for the long comment, but I wanted to ensure that you knew all of the positives and negatives of this cleaner to help you decide if this is appropriate for your needs. If you check my name, you'll know that I'm in no way connected to the manufacturer or Amazon.]
I bought a Eureka a few months ago during a Lightening Sale. I just placed an order for another Eureka vacuum. A battery replacement is nearly the same cost as the entire machine -- $21 for the Eureka 60776 Vacuum Battery Pack.
I absolutely love this micro-vacuum cleaner. I now rarely use the full-sized vacuum cleaners. I hate dragging out the heavy machines (one for the wood floors and one for the throw carpets) and dealing with the electric cord.
The reason why I bought the Eureka was because I was going through a ton of Swiffer dry clothes. The dry mop heads are nearly useless when they get small particles (size of beach sand) on them. By first doing a quick vacuum, the particles are removed then the Swiffer pads last much longer. Yes, it's a two step process but trust me, it's quick.
This Eureka vacuum is more suited for *minor* clean ups. Since I don't have pets that shed, I'm only picking up small particles. Don't expect the Eureka to be a substitute for a full-size machine under normal family conditions.
Due to the Eureka's light-weight and lack of an electric cord, the Eureka vacuum cleaner is absolutely ideal for people who are disabled or elderly or anyone else who wants to get the job over with as quickly as possible.
Because the head of the cleaner is only 10" wide, the head can fit into way more smaller spaces than a full sized vacuum cleaner can. This is a major positive attribute.
After I use the Eureka, I use
Sweeper Dry Sweeping Cloths Mop and Broom Unscented Floor Cleaner 48 Count to remove the fine dust that vacuum cleaners can't remove.
Seriously, my house has never been cleaner. I use the Eureka vacuum daily. The Eureka is lightweight and portable. I walk around barefoot and I can't stand feeling little particles on the soles of my feet.
After the Ni-Cad battery has been cycled a few times, the battery lasts long enough to clean my entire (small) 2 story house -- about 20 minutes. Initially, the battery will only last, maybe, 10 minutes/charge.
Tip: Don't recharge the Ni-Cad battery each time. Let the battery run low (but don't fully discharge the battery) before recharging. The battery will last longer.
Noise: The Eureka is fairly noisy. I have a specialized full-sized vacuum cleaner that makes less noise than the Eureka. I can't use the Eureka when people are sleeping.
You have to clean the filter outdoors. It's fairly messy. Don't open the canister with the filter indoors. I don't go bonkers trying to remove all of the dust from the filter since a little caking makes for a better filter.
