ECOVACS DEEBOT 661 Cordless Robot Vacuum

Battery life runs 90-120 minutes on a single charge, which covers most average-sized homes in one session.

It works well on hard floors like tile, hardwood, and laminate, plus low-pile carpets. High-pile rugs and shag carpeting are more challenging for this model.

The noise level is moderate. Most owners find it acceptable to run while at home.

For pet hair, look for vacuums with strong suction (minimum 20,000 Pa for robot vacuums, 150+ AW for cordless), specialized pet hair attachments, and HEPA filtration that captures 99.97% of particles. Top-rated options include the Dyson V15 Detect ($749), Shark Navigator Lift-Away ($199), and Bissell Pet Hair Eraser ($329). According to our price tracking data, these vacuums maintain consistent 4.5+ star ratings across thousands of reviews.

Most vacuum filters should be replaced every 3-6 months, depending on usage frequency and household conditions. HEPA filters typically last 12-18 months with regular cleaning. For bagless vacuums, clean washable filters every 1-2 weeks. Replacement filters cost between $15-$50 depending on the brand. Failing to replace filters can reduce suction power by up to 50%.
