I Have the Power Max Supra now about 1 year and am thrilled! I bought these. To replace a battery hand vacuum cleaner, which is no longer suitable for larger areas from 1 sq.m. Since I have the electric sweepers, it is getting a slight after cooking quickly the kitchen floor crumbs free. This takes less than 20 seconds for as little machine is ready to hand tucked behind the door. So far, I always had to get the big vacuum cleaner or a broom and shovel. Also on the living room rug, he looks good and some days I will spare me even the big vacuum cleaner! Other benefits include: 1. Lightweight and portable 2. very articulated - to get anywhere 3. the stooping can be avoided to sweep up. Important for back problems 4. Battery life relatively long 5. Reasonable price - usually cheaper than a reasonable cordless vacuum cleaners 6. Easy to clean (except have long hair caught) They have one disadvantage, however. It is the inclusion of long hair. This lies in the sweep of the property. Long hair can not sweep up with a role you. Since the large vacuum cleaner is clearly forward, but I did not actually already clear before buying! Anyone who thinks he can be this little battery operated sweeper set to replace, for example, his big Vorwerk vacuum cleaner, is certainly not happy! As "dust" suckers also works at all because dust one can not eliminate with shovel and broom! It is just a "sweepers" and nothing else! From me definitely a strong buy recommendation for the fast sweeping in between! Would also long hair swept up, I would have awarded full marks!
