Consider investing in a robotic vacuum, which could run at night and pick up most surface dirt. Robotic vacuum cleaners are programmable, and some of the newer designs do a good job of getting into corners. Another option is a stick vacuum. Lightweight and portable, a stick vacuum cleaner is easier to use and control than a full-size upright vacuum cleaner. If you need something for deep cleaning, consider a Miele canister vacuum cleaner. Canister vacs weigh less than uprights and don’t require as much shoulder strength.
