Rotovac 360XL High Performance Carpet Cleaning Machine

I've used the rx-20 for 22 years. it's great for large open areas. i gave up on it. The rotovac 360 xl has better air flow, is more ergonomic and leaves the carpet dryer. With the 3/4 hp motor on the 360 xl it never bogs down even when cleaning concrete with 1/8 in thickness of old forklift tires, worked great. I've now cleaned carpets for 37 years. I clean 3 to 4 jobs of carpet cleaning 5 days a week. I've used the rx-20, too heavy on the my right shoulder and too aggressive on weak seams. I've owned the rotovac swinger with the use of a small portable, too small, too slow, but worked. I've wned and used the rdm.. tooo slow and not enough. rinse. waste of time! i 've used the T-rex too awkward and too much open area of suction slots. i've owned the rotovac powerwand, too aggressive and to slow for my truckmount. i've owned the 360 i , too small for my truck mount. i've used the power glide. too heavy and slow. I own 2 rotovac 360 xl and am total happy about the performance of cleaning, speed ergonomic and selection of cleaning heads. In a large room i can run the 360 with one hand using the right handle and a hairband (cruise control) on the left handle, love it. I even use the hard surface head to strip wax with. my truck mount is custom, has 800,000 Btu of heat available and a 11 gpm pump and 480 cfm at 13 " of hg. i use 8 spray jets under it and it strips wax great. the air flow is superb on the 360 xl. i've made 3 modification on the 360 unique to my needs. Can't do that on the rx-20. I very much like the rotovac xl. Yes, i am very wordy and have my own opinion. i've earned it after 37 years of cleaning carpets. I believe the rotary power head should match the truck mount or portable that you are using.
