It just keeps blowing me away how every time the vacuum cleaner question comes up all you so called professional carpet cleaners recommend the cheapest of residential grade junky vacuum cleaners. If all you want to do is make it look like you are vacuuming why don't you just take one of these broken down old junkers and install a loud speaker and tape recorder in were the bag would usually be. This may prove to be more economical from your perspective and you would still be able to provide your client with the wow factor.
Mardie, I'm a long time lurker, seldom poster, but I gotta say...
Several years ago, the "what vacuum do you guys have on your truck?" question came up (as it frequently does), and Mikey took a sound beating over his recommendation of the Bissel Momentum. I went out and bought this vacuum, and was *completely* blown away by how well it cleaned. Yes, it was a total POS vacuum, and Mikey warned everyone that it was. My first one lasted about a year. I bought another one, but unfortunately it's on it's last legs, and I can't seem to find the same model anymore (think it has been discontinued).
It's too bad Bissel couldn't have made that vacuum a bit higher quality... it had some serious cleaning ability.
Who cares about the image of the product used, as long as the results are there? Aren't the results what really matters? Don't dismiss a product out of hand just because you don't see it as a "professional grade" tool.
After having such great results with the Momentum, you can bet I'll be heading to Costco to grab the Shark Navigator Pro that Mikey is recommending. At that price, I don't care if i have to replace it every year. I only care that it does a great job of vacuuming.
