Adequately functions....very quiet and yet enough suction....lightweight and easy to change hose and/or attachments. Irritating design problem........manufacturer should have the vacumn exhaust blowing away from the user. The user gets the vacumn air exhaust whenever they face the machine. This is particularly irritating to me ...... a simple design change would make this a much better product. Overall good desigh features with enclosed wires along the wand, movement and ease of movement in the wheel base, simple switches and adjustment control.....just the problem with exhaust air.Takes ones' breath away----and makes you not want to look at the vacumn tank when your moving ..... too bad....it's a very nice product otherwise.
