I bought the battery vacuum cleaner because the old (from other manufacturers) had given up the ghost. Cordless vacuum cleaner - Since I already have a cordless hedge trimmer from Ryobi, the Ryobi was purchased. Very good workmanship. The Ryobi is very powerful for a cordless vacuum cleaner. For me, no comparison with the conventional cordless vacuum cleaner. Easy to clean. Robust and solid Cordless vacuum cleaner. However, the battery needs to be purchased separately. My wife is very excited about this cordless vacuum cleaner.
