Makita LXT Vacuum, great if you have Makita LXT batteries from their other gear. Apparently much more power than rechargeable similar Vax etc (18V vs 10.8). And it charges in 20 minutes rather than hours.
Seems a good price for a brand new unit, over £50 on Amazon. I bought one.
Note: You will need to buy a charger and battery if you do not own Makita LXT range.
