This is a very powerful DustBuster. We primarily use it to vacuum up all the cat litter on the floor by the litter box. It has great power. I also own another Black & Decker DustBuster, but a 20 volt model. These two machines are both excellent and there is virtually no difference with their degrees of power. This 14.4 volt costs $50 less than the 20 volt model. in addition, this is the absolute cheapest website to buy this DustBuster at. On other websites, this is going for $42 on the low end to $80 on the high end. This cost me $33. Plus, free shipping! No minimum order required for free shipping! Tyler Tool got a new customer: me.
