Black & Decker DustBuster DV9610N £29.96 Costco in store

£42.39 on Amazon. Gets reasonable reviews. Seems to be in store only. This is the 9.6v model - there was also an 18v but didn't check the price.

This Dustbuster has 9.6V of power which can be used for many tasks around the home. With cyclonic action, dirt and debris is spun around the outside of the bowl helping keep the filter clean at all times. The double filtration system allows the unit to provide higher performance for longer.

Designed to be light and space saving, by moving the motor inside the filter this unit has a lightweight form while providing excellent performance clearing up spills. With the translucent bowl, it can clearly be seen if the Dustbuster needs emptying. Once it is full, emptying the bowl is an easy task; the quick release nozzle allows access to all the dirt and debris that the powerful cyclonic action has collected.
