Quick question to all you T-Rex owners... I recently purchased a T-Rex Jr and when I it I noticed that the larger T-Rex was shipped to me instead of the Jr. My issue is that I don't know if I will want to deal with the extra weight of the original. It is 69 lbs vs 50 lbs for the Jr. I understand that the larger one will clean faster in open areas but it may be too big for furnished homes (95% of my work are furnished homes). My other concern is dealing with the issues of returning the big one and having to wait for the new one. Not sure if I really want to wait or deal with that. So, what are your thoughts? Should I keep the one that was shipped to me or get it replaced for the Jr. which is what I ordered in the first place... and please don't accuse me of trying to take advantage of a wrongly shipped unit. It would probably cost the company more in the extra shipping to have it replaced than what was lost by shipping me the incorrect unit.
