I was looking for a handheld vaccum cleaner to for my car and shortlisted the Dirt Devil and Electrolux Z61A. After reading reviews on Argos and Amazon, decided to go for Dirt Devil. Its definitely powerful than those 12V battery operated vacs.
I was keeping an eye on prices since about three months and got it today from local store of T J Huges in Bradford.
Argos price is £49.99 while Amazon is selling it at £43.97.
TJ Huges is selling both online and instore. If you're buying online, don't miss 4% cashback from Quidco.
