This vacuum was recommend to me by our housekeeper.  I bought 2 of these vacuums 5 months ago and am so happy with them. I have a 6 bedroom inn and 10 cottages. The suction is fantastic - better than Dyson- and unlike the Dyson that cost 2x as much it does not lose suction. It is super easy to clean. The cost to operate is good because you can take the cannister, innards and filter out easily to wash. I bought an extra filter as it takes 24 hours to dry. We do this weekly and it keeps the vacuum running like new. We take dogs in some rooms and this vacuum it the best one I have had in 13 years. We have both carpet and wood floors and the vacuum works well on both. I highly recommend this vacuum for its awesome unwavering suction!
