I am not yet 70 (68), but for those who still do your own housework and mention vacuuming and swiffers to keep up with dog hair, I’d like to suggest a robo-vac. I have a natural long-haired Shih Tzu and I have the RoboRock vac (which vacs and mops) programmed to run at 10:15AM and 2:15PM weekdays and keeps the floors perfectly clean! Mine’s been running this schedule for the past 4 to 5 years. I’ve suggested the same to several friends and now they love theirs also. Priceless!
Best regards.
