Reverse-first cleaning keeps the side brush away from wet spills and lets the mop attack liquid before a forward pass. The strategy improves targeted spill cleanup.
Pros: Mopping performance, Overall opinion
Cons: Edge and Baseboard Cleaning (Hard Floors), Price and Value
Reverse cleaning was praised when the robot mopped backwards and forwards on wet messes.
Pros: Obstacle Avoidance (Robot), Maintenance requirements
One reviewer reports strong pickup in both forward and backward passes, adding useful cleaning efficiency.
Pros: Overall opinion, AI, Smart, App and Automation
Cons: Comparative performance, Crevice / Groove Pickup (Hard Floors)
Reverse-pass cleaning was strong in Project Farm’s plastic-ball test, where the Kenmore picked up remaining debris on the return pass.
Pros: Overall opinion, Weight
Cons: Hair‑Wrap / Tangle Resistance, Crevice / Groove Pickup (Hard Floors)
The blower and reverse function drew repeated praise for keyboards, car debris, inflatables, and dusting, though one review showed it as assistance rather than a complete substitute.
Pros: Overall opinion, Reverse cleaning performance
Cons: Controls and UI, Suitability for heavy-duty use
Full-power pickup works in both forward and reverse passes, reducing the need to repeat the same path.
Pros: AI, Smart, App and Automation, Emptying and Mess Control
Cons: Dock noise, Battery and Charging
Reverse-pass performance was positive, with rice and debris pickup working well in forward and backward sweeps.
Pros: Suction and Airflow, Overall opinion
Cons: Weight, Noise level
Reverse cleaning was praised where tested, with Direction Detect helping backward pulls and reverse oat pickup.
Pros: Hard Floor — Fine Dust Pickup, Overall opinion
Cons: Weight, Noise level
Reverse-pass carpet performance was good but not perfect, with one test noting the Stratos missed more sand than Dyson on the return pass.
Pros: Convertible handheld design, Overall opinion
Cons: Odor control, Weight
Reverse cleaning was mixed: one lab review found slight reverse struggles, while another linked straight-line effort to the swivel floorhead.
Pros: Under-Furniture Pickup, Versatility
Cons: Tool-change simplicity, Onboard tool storage
Reverse cleaning had limited but negative evidence, with one test saying the head plowed debris when pulled backward.
Pros: Suction and Airflow, Debris illumination
Cons: Price and Value, Weight
Reverse cleaning was a weak spot in one hard-floor test because debris pooled and pinged around.
Pros: Emptying and Mess Control, Suction and Airflow
Cons: Price and Value, Hair‑Wrap / Tangle Resistance
Reverse pickup is the clearest weak spot: one reviewer called it the biggest drawback, and another saw leaking or poor residue behavior after a heavy mess.
Pros: Self-cleaning cycle, Overall opinion
One direct test found that pickup seemed to happen mainly on the forward pass, making reverse cleaning noticeably weaker.
Pros: Overall opinion, Suction and Airflow
Cons: Bin and Bag
Reverse passes can be weaker than forward cleaning on hard floors. One test left tea and oats caught behind the wheels when pulling the vacuum backward.
Pros: Ease of use, Overall opinion
Cons: Weight, Bin and Bag
Reverse remote movement is a weak spot in one test because the roller's forward pull makes backing up slow.
Pros: Overall opinion, Steam Cleaning
Cons: Price and Value, Weight
Reverse cleaning evidence was limited and negative, with one review saying cleaning was only really effective when moving forward.
Pros: Overall opinion, Self-cleaning cycle
Cons: Suitability for heavy-duty use
