I would go with the Aerus/Lux Shampooer's. Easy to use, splash guard is wonderful for keeping suds off of woodwork and furniture that you are not moving. Tray to set it in, this tray also keeps the brushs up so the brushes won't get smashed down. I was disappointed when they did away with the cord winder, but you get a much longer cord in the trade off. I used mine a few months ago, mine has the cord winder and I used a heavy duty extention cord due to the short cord. Ease of cleanup is a breeze. In the past I have used hoovers, rug doctor, blue lustre and none compare. On top of that they have a dry suds Turbo Shampoo that is absolutely wonderful. The tank has water marks and you add a capfull per line and by capfull I mean the tank cap itself, how much easier than that......
One more thing, the shape is unique and allows you to get into tight corners and around things more easily. As we get older, there are some items that cannot be moved easily and as long as you are careful and keep a micro fibre cloth with you and wipe the legs if any shampoo happens to get on them, problem solved. I have jewel tone carpets and shampoo once or twice a year. The shampoo also brings back the brightness to those jewel tones.
PS, almost forgot, cleanup is a breeze, after shampooing.
Procare knows way more than I do about this and as he said, you may want to pm him.
Sincerely,
Bud
