Query: dustbuster is busted

I have always kept a dustbuster in my kitchen for quick clean ups. They are always charged. Not with this new 18 volt model. Not only does is not have much suction power, you can't keep the battery plugged in so it is always charged and ready to go. If you don't use it for 4-5 days, the charge depletes! So then you have to recharge it for 14-16 hours. Not convenient at all. So I returned the dustbuster. I then ordered a Eureka that works great and can be left plugged in, permanently. The model number is H96. It is not as large as it looks in the photos and is a great buy; not to mention it costs less than the inefficient new dustbusters. The new dustbuster models are now just cheap knock offs of the original great machines. Black and Decker in their attempt to make a higher profit by cheapening a previously great product, destroyed a really good thing.I strongly recommend the Eureka below:Eureka Quick Up Cordless 2 in 1, 96Hproduct.
