After a few days of use I delivered a very positive opinion (check in time) ... The power is with go, the suction also perfect with my sled. Autonomy is entirely appropriate that my little apartment 43m². How fortunate not to have to leave his sled handle his pipe its cable etc ... We always grab the vacuum cleaner and broom ready hop home is always spot on! From time to time for further cleaning is apparent the sled. Weight? Indeed those who expect to handle a broom must abstain. Although 1 kilo lighter than the identical products with NiMh batteries, it remains a dead weight of 2.5 kg. But the ergonomic handle, casters and flexibility make it very handy. By cons, if you must pick up stairs you'll probably just your biceps muscle. The sound? Compared to my sled I find it a bit quieter at minimum speed and an equivalent noise at top speed. But frankly the maximum speed is rarely useful. It really sucks great. To see in the time now but for the right time purchase especially as enjoying probably a promo I have paid 171! More than 200 I'm not sure I would have bought. The battery life is 3 years and a replacement battery is about 70. So if you put in a little pig 2 coin each month, in time, the battery will already paid! QED! Regarding the Li-Ion batteries, unlike NiMH, they have little or no "memory effect". This means you can charge your Li-Ion batteries as soon as you like and preferably as much as possible to prevent wear. Unlike Ni-MH batteries that it is better to recharge when they are almost empty to maintain their original capacity.
